Star Wars: Knights of the Old Republic/Combat

Attack

Attacks with weapons cannot normally hit and subsequently damage an opponent unless an attack roll is equal to or greater than that opponent's Defense. An attack roll is the sum of the roll of a twenty-sided die (d20) and all attack bonuses and penalties. According to Feedback, a minimum d20 roll (1) is an automatic miss while a maximum d20 roll (20) is an automatic hit (and Critical Threat), so chance to hit has a minimum of 5% and a maximum of 95% regardless of whether or not the total attack roll would equal or exceed defense.

Maximum 95% chance to hit is achieved when the sum of 2 (the lowest d20 roll that isn't an automatic miss) and attack bonuses and penalties is equal to or greater than the target's defense.

Base

All characters have a base attack bonus which increases as level increases. Progression varies according to class:

Soldier	Scout	Scoundrel	Jedi			Droid
			Guardian	Sentinel	Consular	Combat	Expert
Fast	Slow	Slow	Fast	Slow	Slow	Fast	Slow

Progression		Level
		1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16	17	18	19	20
Fast	Level	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16	17	18	19	20
Slow	Level × 3/4	0	1	2	3	3	4	5	6	6	7	8	9	9	10	11	12	12	13	14	15

Dual Wield Penalty

Using two weapons or a double-bladed weapon normally incurs an attack penalty, which depends on whether or not the attacker has any Two-Weapon Fighting feat and a balanced weapon (which adds Small Offhand Bonus 2 to the attack(s) of the main hand):

Feat	Unbalanced		Balanced
	Main hand	Off hand	Main hand	Off hand
None	−6	−10	−4	−10
Two-Weapon Fighting	−6	−6	−4	−6
Improved	−4	−4	−2	−4
Master	−2	−2	0	−2

All blaster pistols, Double-Bladed Lightsabers and double-handed melee weapons are balanced, as are a Short Lightsaber, Short Sword and all vibroblades in the off hand.

Feats

Some feats add a bonus to, or inflict a penalty on, the attack roll:

Feat	Base	Improved	Master
Power Blast	−3
Rapid Shot	−4	−2	−1
Power Attack	−3
Flurry	−4	−2	−1

Feat	Base	Improved	Master
Force Jump		+2	+4
Dueling	+1	+2	+3
Weapon Focus	+1

Ranged

According to Feedback, Close Proximity Ranged Bonus 10 is added to the attack roll whenever a ranged attacker attacks any opponent in close proximity. Conversely, melee on ranged 10 is added to the attack roll whenever a melee attacker attacks a ranged opponent. In either case, this can increase chance to hit by up to 50%.

Attribute modifier

Strength mod(ifier) is added to the attack roll when using melee weapons, or lightsabers when equal to or greater than Dexterity mod(ifier).

Dexterity mod is added to the attack roll when using ranged weapons, or lightsabers when greater than Strength mod.

Effect bonus

Some weapons add an effect bonus to the attack roll, as do battle stimulants:

Stimulant	Bonus	Stimulant	Bonus	Stimulant	Bonus
Battle Stimulant	+1	Hyper-battle Stimulant	+2	Echani Battle Stimulant	+3

The dark side power Slow can also inflict a penalty (−2).

Critical Threat

As well as resulting in an automatic hit, an attack roll with a maximum d20 roll (20) results in an automatic Critical Threat. This threat roll is effectively a second attack roll which can result in a Critical Hit, multiplying damage rolls and bonuses when equal to or greater than an opponent's Defense. However, unlike an attack roll, a threat roll cannot automatically miss (roll 1) or hit (roll 20) so conversion of critical threats to critical hits can be 0% (roll 20 + Attack < Defense) and 100% (roll 1 + Attack ≥ Defense).

Unarmed attacks have Critical Threat: 20–20,x2 but don't work with any gloves on: subsequent rolls for Threat Breakdown don't appear even in a case of 20 - Automatic Hit! throw; some weapons have a higher Critical Threat range, increasing the chance of a roll within that range:

Threat	20–20 (5%)		19–20 (10%)
Keen	19–20 (10%)		17–20 (20%)
Ranged weapons	Blaster pistols Heavy blasters Disruptor pistols Ion blasters Sonic pistols	Disruptor rifles Ion rifles Sonic rifles Repeating blasters Heavy repeating blasters	Hold out blasters Blaster carbines Blaster rifles Bowcasters
Melee weapons	Stun batons Gamorrean Battleaxe Short Sword Long swords	Double-Bladed Lightsaber Quarterstaff and Gaffi sticks Wookiee Warblade Double-bladed swords Vibro double-blades	Lightsaber Short Lightsaber Vibroblades Vibroswords

The Keen bonus can increase base Critical Threat range, as can the Critical Strike and Sniper Shot feats. According to Feedback, any Keen bonus is additive with feat bonuses, resulting in the following:

Feat		Critical Threat		Keen
Melee	Ranged	20–20 (5%)	19–20 (10%)	19–20 (10%)	17–20 (20%)
Critical Strike	Sniper Shot	19–20 (10%)	17–20 (20%)	18–20 (15%)	15–20 (30%)
Improved		18–20 (15%)	15–20 (30%)	17–20 (20%)	13–20 (40%)
Master		17–20 (20%)	13–20 (40%)	16–20 (25%)	11–20 (50%)

Defense

Characters can only be hit and subsequently damaged by attacks with weapons when an attack roll is equal to or greater than defense. An attack roll is the sum of the roll of a twenty-sided die (d20) and all attack bonuses and penalties. According to the Feedback, a minimum d20 roll (1) is an automatic miss while a maximum d20 roll (20) is an automatic hit (and Critical Threat), so chance to hit has a minimum of 5% and a maximum of 95% regardless of whether or not the total attack roll would equal or exceed defense.

Minimum 5% chance to hit is achieved when the sum of 19 (the highest d20 roll that isn't an automatic hit) and the attacker's attack bonuses and penalties is less than defense.

All characters start with base 10 defense.

Armor

Body armor adds to defense, but it can also restrict how much of a character's dex(terity) mod(ifier) is added as well: for example, an armor displaying Max Dexterity Bonus: +5 restricts defense added by dex mod to +5, even when it's greater than +5.

Defense Bonus	Light armor		Medium armor		Heavy armor
Armor	4	5	6	7	8	9
Max Dexterity Bonus	5	4	3	2	1	0

The sum of armor and Max Dexterity Bonus is always 9: any additional Defense Bonus is added to feats and effects mod, which is restricted to maximum 10, so maximum defense bonus while armored is 19 (15, if a Jedi doesn't use Force powers restricted by armor before equipping it).

Otherwise, dex mod is unrestricted when unarmored (unclothed, or wearing clothing, disguises or robes). Although the descriptions for disguises and robes display Max Dexterity Bonus: +8, according to Feedback this restriction doesn't actually apply. Maximum 42 Dexterity results in dex mod 16, so maximum defense bonus for an unarmored Jedi is 26.

Class

Some classes are granted a defense bonus which can increase on level up:

Bonus	Level	Class and feat
		Scoundrel	Jedi	Droid
+2	1	Scoundrel's Luck	Jedi Sense	Combat Logic Upgrade
+4	6	Improved Scoundrel's Luck	Knight Sense	Tactician Logic Upgrade
+6	12	Master Scoundrel's Luck	Master Sense	Battle Droid Logic Upgrade

Although this bonus is attributed to a feat, it's entirely dependent on class.

Class bonuses are unrestricted, but since your main character can only gain maximum level 20 this means a maximum class bonus of 10: this can only be achieved at level 18 with any Jedi class (+6) who was a level 6 Scoundrel (+4), since even a level 12 Scoundrel (+6) could only become a level 8 Jedi at most (+4).

Some characters, like unarmored creatures, are also granted a natural bonus.

Feats and effects

Feedback sums defense bonuses and penalties from the following under feats and effects mod:

Feats	Base	Improved	Master
Rapid Shot	−4	−2	−1
Sniper Shot	−5
Flurry	−4	−2	−1
Critical Strike	−5
On Hit: Slowed	-4

Force powers	Base	Improved	Master
Burst of Speed	Burst +2	Knight +4	Master +4
Force Aura	Aura +2	Shield +4	Armor +6
Slow	−2
Force power	Stun	Stasis	Field
Saved	-4

Armor and robes can also have defense bonuses added to feats and effects:

Robes	Light armor	Medium armor	Heavy armor
+(1–5)	+(0–4)	+(0–6)	+(0–5)

Feats and effects from all of the above are restricted to maximum 10: for example, a light Jedi wearing Qel-Droma Robes (+5) and using Master Speed (+4) and Force Armor (+6) only receives a defense bonus of 10, not 15.

However, this also means that penalties can be incurred without reducing defense, since they can be offset by any excess: for example, in this case it makes no difference if Critical Strike (−5) is used since the defense bonus is 10 in either case (15 is restricted to 10, or 15 − 5 = 10).

Any Dueling bonus is listed separately as feat:

Feat	Bonus	Improved	Master
Dueling	+1	+2	+3

Debilitated penalty

Debilitated penalty results in −4 defense whenever a target is debilitated by any of the following:

Feats	Force powers	Equipment
Critical Strikes Sniper Shots	Stun and Stasis (Field) Stun, Disable and Destroy Droid Force Push, Whirlwind and Wave Fear, Horror and Insanity Wound, Choke and Kill	Plasma, Concussion and CryoBan Grenades Flash mines On Hit: Horror, Stun and Paralyze

If a level < 5 character is debilitated then any melee attack in a subsequent combat round is a Death Blow, an automatic hit resulting in instant death, even if no damage is inflicted. Otherwise, being debilitated also means Dexterity modifier isn't added to Defense or Reflex save, and debilitated droids have saves reduced by 2. Characters may avoid being debilitated with a successful save, Immunity: Mind-Affecting, Force Resistance, or Force Immunity feats.

Damage

A successful attack can inflict damage, reducing Vitality. Melee weapons and disruptors inflict physical damage of different types:

Bludgeoning		Piercing		Slashing
Weapon	Damage	Weapon	Damage	Weapon	Damage	Weapon	Damage
Unarmed	1	Short Sword	1–6	Gamorrean Battleaxe	1–12	Wookiee Warblade	1–10
Stun batons	1	Gaffi sticks	1–8	Long swords	1–12	Double-bladed swords	2–12
Quarterstaff	1–6	Vibroblades	1–10	Vibroswords	2–12	Vibro double-blades	2–16
Disruptor pistols							1–4
Disruptor rifles							1–6

Creatures armed with claws also inflict slashing damage. Lightsabers and most ranged weapons inflict energy damage:

Lightsabers	Damage	Blaster pistols	Damage	Blaster rifles	Damage	Heavy weapons	Damage
Short Lightsaber	2–12	Hold out blasters	1–4	Blaster carbines	1–8	Repeating blasters	1–8
Lightsaber	2–16	Blaster pistols	1–6	Blaster rifles	1–8	Heavy repeating blasters	1–10
Double-Bladed	2–20	Heavy blasters	1–8	Bowcasters	1–10

However, disruptors aren't the only ranged weapons that don't:

Sonic		Ion
Weapon	Damage	Weapon	Damage	vs. Droid
Sonic pistols	1–4	Ion pistols	1–4	+1–10
Sonic rifles	1–6	Ion rifles	1–6	+2–12

How much damage is inflicted is normally determined by the roll of a virtual numbered die or dice, which can be expressed with the notation XdY, where X is the number of dice with Y sides rolled:

Damage	1–4	1–6	1–8	1–10	1–12	2–12	2–16	2–20
Notation	1d4	1d6	1d8	1d10	1d12	2d6	2d8	2d10

Minimum total roll is X, while the maximum is X × Y. The more dice are rolled, the more likely the total will approach the average.

+	1	2	3	4	5	6
1	2	3	4	5	6	7
2	3	4	5	6	7	8
3	4	5	6	7	8	9
4	5	6	7	8	9	10
5	6	7	8	9	10	11
6	7	8	9	10	11	12

For example, although a Long Sword inflicts slightly less damage (1–12 or 1d12) than a Vibrosword (2–12 or 2d6), it is equally likely to roll 1, 7 or 12 (1/12 chance each), whereas the Vibrosword is far less likely to roll 2 or 12 (1/36 chance each) but far more likely to roll 7 (1/6 chance).

More advanced weapons of the same type can have additional bonuses, both set or dice rolls, of the same or different damage type(s), like acid, light side and universal. Some damage types may seem to be associated with specific secondary effects:

• Cold damage and On Hit: Paralyze can both be inflicted by carbonite projectors and CryoBan Grenades.
• Fire damage and On Hit: Horror can both be inflicted by flame throwers and Plasma Grenades.
• Ion blasters and rifles have additional ion damage rolls versus droids, and Ion Grenades inflict triple damage on them.
• Sonic damage and On Hit: Attribute Damage Dexterity can both be inflicted by sonic pistols and rifles, and Sonic Grenades.

However, this is not actually the case. For example:

• An Echani Vibroblade (Damage Bonus: +2 Cold) does not paralyze.
• Ajunta Pall's Blade (Damage Bonus: +2 Fire) does not inflict Horror.
• Shield disruptors inflict the same ion damage on organics as droids.
• A Sith Tremor Sword (Damage Bonus: +2 Sonic) inflicts no Attribute Damage Dexterity.

Ion damage is doubled against Shields, but otherwise the only difference damage type makes is which Damage Immunity, shields and Damage Resistance take effect.

Although the following damage bonuses are listed separately in the Damage Breakdown, they're always added to weapon damage and are thus the same type:

• Strength mod(ifier) (melee weapons and lightsabers only)
• Weapon Specialization
• Bonus damage
• Sneak Attack damage

Strength mod and Weapon Specialization are multiplied by a Critical Hit. Bonus damage is normally added by feats:

Feat	Base	Improved	Master
Power Blast	5	8	10
Power Attack	5	8	10

Feat	Base	Improved	Master
Force Jump		2	4

This bonus damage is multiplied by a Critical Hit, then any Massive Criticals bonuses are added.

Battle stimulants are supposed to grant a damage bonus but, according to Feedback and contrary to their descriptions and what's displayed on the Equip screen, they don't actually do so.

Critical Hit

A Critical Hit is triggered when the d20 roll of a successful attack roll is within the weapon's Critical Threat range, and then a second attack or threat roll is also successful. This results in a multiplication of weapon damage rolls, bonuses and penalties. Critical Multiplier is x2.

However, the following are not multiplied by a Critical Hit:

• Set item bonuses (like Crystal, Sapith's Damage Bonus: 3, Energy)
• Sneak Attack damage

Any Massive Criticals bonus is only added to bonus damage on a Critical Hit, and not multiplied by it:

Weapon	Description	Bonus	Weapon	Description	Bonus
Melee weapon	Bacca's Ceremonial Blade	+2–12	Upgrade item	Crystal, Opila	+2–12

For example:

Damage Breakdown	Source	Damage roll	Critical Hit
			Roll 2	Total
Energy	Lightsaber	2–16	+2–16	4–32
	Crystal, Opila (Damage Bonus: 3, Energy)	3		3
	Crystal, Sigil (Damage Bonus: 1–6, Energy)	1–6	+1–6	2–12
Physical (slashing)	Jedi Guardian dark mastery	1–8	+1–8	2–16
Strength mod	32 Strength	11	+11	22
Weapon specialization	Weapon Specialization: Lightsaber	2	+2	4
Bonus damage	Master Force Jump (level 12 Jedi Guardian)	4	+4	8
	Crystal, Opila (Massive Criticals: +2–12)		+2–12	2–12
Sneak attack damage	Sneak Attack IV (level 7 Scoundrel)	4–24		4–24
Total		28–74	+13–59	51–133

Taking chance to hit (attack roll success), Critical Threat and critical conversion (threat roll success) into account, the chance of any hit becoming a Critical Hit is as follows:

Roll success		Critical Threat
Attack	Threat	20 (5%)	19 (10%)	18 (15%)	17 (20%)	16 (25%)	15 (30%)	13 (40%)	11 (50%)
95%	100%	5%	10%	15%	20%	25%	30%	40%	50%
95%		4.75%	9.5%	14.25%	19%	23.75%	28.5%	38%	47.5%
90%		4.5%	9%	13.5%	18%	22.5%	27%	36%	45%
85%		4.25%	8.5%	12.75%	17%	21.25%	25.5%	34%	42.5%
80%		4%	8%	12%	16%	20%	24%	32%	40%
75%		3.75%	7.5%	11.25%	15%	18.75%	22.5%	30%	37.5%
70%		3.5%	7%	10.5%	14%	17.5%	21%	28%	35%
65%		3.25%	6.5%	9.75%	13%	16.25%	19.5%	26%	32.5%
60%		3%	6%	9%	12%	15%	18%	24%	30%
55%		2.75%	5.5%	8.25%	11%	13.75%	16.5%	22%	27.5%
50%		2.5%	5%	7.5%	10%	12.5%	15%	20%	25%
45%		2.25%	4.5%	6.75%	9%	11.25%	13.5%	18%	20.25%
40%		2%	4%	6%	8%	10%	12%	16%
35%		1.75%	3.5%	5.25%	7%	8.75%	10.5%	12.25%
30%		1.5%	3%	4.5%	6%	7.5%	9%
25%		1.25%	2.5%	3.75%	5%	6.25%
20%		1%	2%	3%	4%
15%		0.75%	1.5%	2.25%
10%		0.5%	1%
5%		0.25%
5%	0%	0%

Since an attack roll must succeed before any threat roll can be made, if chance to hit < Critical Threat then Critical Threat is restricted to chance to hit. For example, 10% chance to hit (roll 19–20 + Attack ≥ Defense) means that a Lightsaber inflicts no more damage with Master Critical Strike (Critical Threat: 13–20,x2) than a standard Attack (Critical Threat: 19–20,x2) since roll 13–18 + Attack < Defense, resulting in a miss on an attack roll, and failure to convert on a threat roll. Consequently, the chance of any hit becoming a Critical Hit is only 1% (0.1 × 0.1 × 100) in both cases.

Average damage multiplier per attack = Attack success + (Threat success × min(Critical Threat, Attack success))

For example:

Action	Critical Threat	Attack and Threat success
		75%	50%	25%
Attack	19–20 (10%)	0.825 (0.75 + (0.75 × 0.1))	0.55 (0.5 + (0.5 × 0.1))	0.275 (0.25 + (0.25 × 0.1))
MCS	13–20 (40%)	1.05 (0.75 + (0.75 × 0.4))	0.7 (0.5 + (0.5 × 0.4))	0.3125 (0.25 + (0.25 × 0.25))

If the Lightsaber normally averages 30 (17–43) damage per hit (excluding set item bonuses, Massive Criticals and Sneak Attack), then average damage per attack is as follows:

Action	Critical Threat	Attack and Threat success
		75%	50%	25%
Attack	19–20 (10%)	24.75 (30 × 0.825)	16.5 (30 × 0.55)	8.25 (30 × 0.275)
MCS	13–20 (40%)	31.5 (30 × 1.05)	21 (30 × 0.7)	9.375 (30 × 0.3125)

Damage Immunity

Damage Immunity versus a specified damage type is an item bonus that first reduces damage of that type by 100% to 0, even before Shields.

Source	Description	Cold	Fire	Sonic	Electrical
Medium armor	Environmental Bastion Armor	100%	100%	100%
Belts	Electrical Capacitance Shield				100%
	Thermal Shield Generator		100%

Damage Immunity is normally excessive since a combination of high saves, (Improved) Energy Resistance or Damage Resistance can normally significantly reduce these damage types, or even negate them entirely.

Damage Immunity: 100% vs. Electrical doesn't affect the Force point damage of Force Storm. Overloading computer terminals you're currently using can inflict up to 1000 electrical damage to all in the area of effect, but you can just... not do that.

Shields

A shield can absorb any damage of the specified type(s) remaining after Damage Immunity. Organic characters can equip a shield on each arm, although only one shield can be active at a time: using a shield replaces any already active. Each shield charge has a duration of 200 seconds, or until maximum damage has been taken. Any damage absorbed, and points remaining, are recorded in Feedback.

Shield	Damage Deflection
	Points	Energy	Sonic	Cold	Heat
Energy Shield	20	Yes	No	No	No
Echani Dueling Shield	60	Yes	No	No	No
Yusanis' Dueling Shield	100	Yes	No	No	No
Sith Energy Shield	30	Yes	Yes	No	No
Echani Shield	50	Yes	Yes	No	No
Arkanian Energy Shield	40	Yes	Yes	Yes	Yes
Verpine Prototype Shield	120	Yes	Yes	Yes	Yes

Shields effectively add Vitality versus the specified damage type(s). Organic characters can equip a Mandalorian shield to absorb physical damage instead:

Shield	Damage Deflection
	Points	Energy	Bludgeoning	Piercing	Slashing
Mandalorian Melee Shield	20	No	Yes	Yes	Yes
Mandalorian Power Shield	30	Yes	Yes	Yes	Yes

However, you can only get three Melee Shields and one Power Shield. Droids can also equip a shield:

Shield	Droid Upgrade	Damage Deflection
		Points	Energy	Sonic	Cold	Heat
Energy Shield Level 1	Class 1	20	Yes	No	No	No
Baragwin Droid Shield	Class 1	20	Yes	No	No	No
Energy Shield Level 2	Class 2	30	Yes	No	No	No
Energy Shield Level 3	Class 3	50	Yes	No	No	No
Environment Shield Level 1	Class 1	20	Yes	Yes	Yes	Yes
Environment Shield Level 2	Class 2	30	Yes	Yes	Yes	Yes
Environment Shield Level 3	Class 3	50	Yes	Yes	Yes	Yes

Contrary to their descriptions, shields do not deflect electrical damage. Ion damage is doubled against any active shield.

Toughness

The feats Improved or Master Toughness, and Wookiee Toughness, reduce any damage remaining after shields by 2. Toughness can be surprisingly effective since it affects each of the following separately:

• Sum of weapon damage
• Sum of bonus damage rolls of each type
• Sum of set item bonuses of each type

For example, Improved, Master or Wookiee Toughness would have the following effect:

Source	Damage			Toughness
	Type	Minimum	Maximum	Minimum	Maximum
Lightsaber	Energy	2	16	0	14
Crystal, Sapith	Energy	4	4	2	2
Crystal, Solari	Energy	1	8	0	6
	Light Side vs Dark Side	2	12	0	10
Jedi Guardian dark mastery	Physical (slashing)	1	8	0	6
Total		10	48	2	38

Damage is affected five times in this case, but Feedback's Damage Breakdown only lists Toughness once. However, these multiple effects can be detected by comparing listed damage to expected damage: this is clearest with rolls and set bonuses of different types (for example, light side or physical not being listed on roll 1–2), but can also be seen when the total is less than the expected minimum.

Damage Resistance

Damage Resistance versus a specified damage type reduces any damage of that type remaining after Toughness, by a set amount. However, bonuses do not sum: only the highest ever has any effect. Any damage resisted is recorded in Feedback.

Resistance	Source	Maximum
Bludgeoning	Brejik's Belt	5/−
Slashing	Brejik's Armband	5/−
Electrical	Mandalorian Battle Armor	25/−
Energy	Improved Energy Resistance	15/−
Cold	Mandalorian Assault Armor	25/−
	Verpine Zal Alloy Mesh

Resistance	Source	Maximum
Fire	Darth Bandon's Fiber Armor	25/−
	Mandalorian Assault Armor
	Verpine Zal Alloy Mesh
Sonic	Powered Light Battle Armor	25/−
	Verpine Zal Alloy Mesh

/− simply means that the value is subtracted from that damage type.

Damage Resistance: Resist 15/− vs Electrical, Energy, Cold, Fire and Sonic can be granted to the entire party by Improved Energy Resistance from level 9, for 120 seconds (2 minutes): while this isn't the maximum against all those damage types, it is normally sufficient protection, particularly since successful saves normally halve the damage of Force powers, grenades and droid special weapons beforehand.

Like Toughness, Damage Resistance affects each of the following separately:

• Sum of weapon damage
• Sum of bonus damage rolls of specified type
• Sum of set item bonuses of specified type

This makes Damage Resistance more effective against advanced weapons with these bonuses. For example, an enemy using two special Vibroswords normally inflicts 14–24 (9–19,+5) slashing damage with each, but Brejik's Armband's Damage Resistance: Resist 5/− vs Slashing affects this twice, reducing it to 4–14 (4–14,+0): this is no better than a basic Vibrosword, which would only be affected once.

Source	Description	Bludge	Slash
Arms	Brejik's Armband		5
Belts	Brejik's Belt	5

Source	Description	Electrical
Powers	(Improved) Energy Resistance	15
Heavy	Mandalorian Battle Armor	25

Brejik's Armband and Belt are unique, so only one of your party can equip each of them. Slashing damage is more common and normally higher than bludgeoning damage, so the armband is more useful than the belt.

Combat Difficulty

Adjusting Combat Difficulty in Gameplay Options at any time has the following effect on damage from enemy attacks:

Difficulty	Enemy Damage	Final Damage
		1	2	3	4	5	6	7	8	9	10
Easy	50%	0	1	1	2	2	3	3	4	4	5
Normal	100%	1	2	3	4	5	6	7	8	9	10
Difficult	150%	1	3	4	6	7	9	10	12	13	15

Final enemy damage is reduced by 50% on Easy and increased by 50% on Difficult, rounding down in both cases. This includes 'friendly' fire from grenades, and returned blaster bolts.

Vitality

The red bar represents a character's health, measured in vitality points. Vitality points (VP) decrease when a character takes damage from an attack or other effect. If the total reaches zero, the character falls unconscious and is unable to move or fight until healed. If the entire party falls unconscious, the game will end. To continue, load a previously saved game or begin from the last AUTO SAVE point. As long as one character in the party remains conscious to guard the others, the game will continue.

Characters are granted the following Vitality per class level:

Vitality per class level	6	8	10	12
Classes	Scoundrel Jedi Consular	Scout Jedi Sentinel Expert Droid	Soldier Jedi Guardian Minion	Combat Droid

Feat	Base	Improved	Master
Toughness	+1		+2

Feat	Base	Improved	Master

Vitality bonuses are also granted by battle stimulants:

Stimulant	Vitality	Stimulant	Vitality	Stimulant	Vitality

Regeneration

NOTE: Unlike Force points, vitality points do not regenerate and must be healed through the use of Force powers, medpacs and other items.

While this is normally true, the Regeneration bonus allows it to do so. However, any lost Vitality only regenerates once every 6 seconds (every two combat rounds):

Source	Description	Bonus
Implants (Level 3)	Sith Regenerator	2
	Navardan Regenerator
Robes	Darth Revan's Robes	1

Source	Description	Bonus
Canderous	Unique ability	4
HK-47	Third repair	1
	Fourth repair	1

Maximum Regeneration: 6 for Canderous, or averaging just 1 per second. HK-47's Regeneration bonuses sum, so after his fourth repair he has Regeneration: 2.

Cleave

When any character kills with a ranged or melee attack (or a droid special weapon), then that character can perform an extra action in that combat round: if the action queue is empty or cleared then this is an automatic Attack if a target is in range (which may include taking a step or two in melee range), otherwise it's the next action queued against another target in range, whether that's a combat feat, Force power (including buffs targeting you or your party), grenade or item use. If no action is queued against a target in range, and no target is in range, then there's no extra action.

If you attack and kill from Stealth then the extra action doesn't count as a Sneak Attack. If the extra action kills the next target as well then this doesn't trigger another extra action, so two is the maximum that can be killed by a character's attacks (or a droid special weapon) in a single combat round. Thus inflicting enough damage to kill targets in a single round can significantly increase kill speed:

Rounds to kill	Cumulative maximum kills
	Round 1	Round 2	Round 3	Round 4	Round 5
1	2	4	6	8	10
2		1	2	3	4
3			1	1	2
