Star Wars Knights of the Old Republic II: The Sith Lords/Combat: Difference between revisions

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 the Combat log, 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.

All characters have a base attack bonus equal to their character or class level(s). Although enemies normally only have class level 1 and thus base 1, they receive a bonus to this based on your main character level:

Set 1 and Set 2	Set 3	Set 4	Set 5
roundup(main level * 0.9) - 1	roundup(main level * 0.95) - 1	main level	rounddown(main level * 1.1)

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
Feat	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 all Short Lightsabers, short swords and vibroblades in the off hand.

Once Two-Weapon Fighting has been mastered, the Jedi Weapon Master and Sith Marauder Prestige classes can then select Superior Two-Weapon Fighting to reduce this attack penalty even further:

Two-Weapon Fighting	Unbalanced		Balanced
Two-Weapon Fighting	Main hand	Off hand	Main hand	Off hand
Superior I	-1	-2	+1	-2
Superior II	0	-2	+2	-2
Superior III	0	-1	+2	-1

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	0

Feat	Base	Improved	Master
Force Jump		+2	+4
Dueling	+1	+2	+3
Dual Strike	+2	+4	+6
Weapon Focus	+1

All Prestige classes are granted Weapon Focus: Lightsaber and can select Weapon Specialization: Lightsaber, but only a Jedi Weapon Master or Sith Marauder can then select Superior Weapon Focus: Lightsaber.

Superior Weapon Focus	Lightsaber I	Lightsaber II	Lightsaber III
Weapon Focus Bonus	+1	+2	+3

Ranged

Bonuses can be added to the attack roll for close proximity ranged attacks, and melee attacks on ranged attackers, depending on whether or not the attacker, or defender, has any Close Combat feat:

Feat	None	Close Combat	Improved
Close Proximity Ranged Bonus		+1	+2
melee on ranged	+6	+4	+2

Close Combat is granted to level 4 Scouts, but these feats can be selected by all classes except Prestige classes.

Scouts are also granted Targeting feats, which add an attack bonus when using blaster pistols and rifles:

Targeting	I	II	III	IV	V	VI	VII	VIII
Scout level	1	5	9	13	17	21	25	29
Ranged attack	+1	+2	+3	+4	+5	+6	+7	+8

Lightsaber form

Some lightsaber forms add a bonus to the attack roll:

Determination (Shii-Cho)	Contention (Makashi)	Perseverance (Shien)	Moderation (Niman)
+1	+3 (vs lightsaber)	+2	+1

Attribute modifier

Strength mod(ifier) is normally added to the attack roll when using melee weapons and lightsabers.

Dexterity mod(ifier) is added to the attack roll when using ranged weapons. If greater than strength mod, then it can be added to melee attack rolls instead of Strength modifier after selecting the Finesse: Melee Weapons feat, and to lightsaber attack rolls after selecting either of the Finesse: Melee Weapons or Lightsaber feats.

Player Charisma Modifier is also added to your party's attack rolls, but not your own.

Effect Bonus

Some weapons and items add an effect bonus or penalty to the attack roll, as do the following Force powers and stimulants:

Force power	Effect Bonus
Force power	User	Party	Enemy
Battle Meditation	+2	+2
Improved Battle Meditation	+2	+2	-2
Master Battle Meditation	+4	+4	-4
Inspire Followers I-V	+(1-5)	+(1-5)
Crush Opposition I-V			-(1-5)
Slow			-2

Stimulant	Effect Bonus
Stimulant	User	Party	Enemy
Battle Stimulant	+1
Hyper-battle Stimulant	+2
Echani Battle Stimulant	+3

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).

Ferocity (Juyo) lightsaber form adds 4 to the threat roll, although the only indication of this in the Combat log's Threat Breakdown is if there's threat success with Attack < Defense (for example, threat success with Attack 40 vs Defense 44; without this form, success would require at least Attack = Defense, or 44).

Unarmed attacks have Critical Threat: 20-20,x2 but some weapons have a higher Critical Threat range, increasing the chance of a roll within that range:

Threat	20-20 (5%)		19-20 (10%)	18-20 (15%)
Keen	19-20 (10%)		17-20 (20%)	15-20 (30%)
Ranged weapons	Blaster pistols Heavy blasters Ion blasters (x3) Sonic pistols	Ion rifles (x3) Blaster carbines Sonic rifles (Heavy) repeaters	Hold out blasters Bowcasters (x3) Blaster rifles	Disruptor pistols Disruptor rifles
Melee weapons	Stun batons Short swords Gamorrean battleaxes Long swords	Double-Bladed Lightsaber Quarterstaffs and Force pikes Double-Bladed Sword Vibro double-blades Freyyr's Warblade	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 the Combat log, any Keen bonus is additive with feat bonuses, resulting in the following:

Feat	Critical Threat			Keen
Feat	20-20 (5%)	19-20 (10%)	18-20 (15%)	19-20 (10%)	17-20 (20%)	15-20 (30%)
Critical Strike / Sniper Shot	19-20 (10%)	17-20 (20%)	15-20 (30%)	18-20 (15%)	15-20 (30%)	12-20 (45%)
Improved	18-20 (15%)	15-20 (30%)	12-20 (45%)	17-20 (20%)	13-20 (40%)	9-20 (60%)
Master	17-20 (20%)	13-20 (40%)	9-20 (60%)	16-20 (25%)	11-20 (50%)	6-20 (75%)

Resilience (Soresu) lightsaber form can then decrease weapon Threat range by 1 (5%) to minimum 20-20 (5%), while Aggression (Ataru) lightsaber form increases it by 1 (5%) to maximum 10-20 (55%) using a Keen (Short) Lightsaber with Master Critical Strike.

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 Combat log, 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	Jedi armor	Light armor		Medium armor		Heavy armor
Armor	3	4	5	6	7	8	9
Max Dexterity Bonus	4	5	4	3	2	1	0

The Minor Uniform has armor 1, but no Max Dexterity Bonus.

Any remaining Defense Bonus is added to feats and effects mod. Some armors have higher Max Dexterity Bonus, and underlays can increase it for any heavy armor:

Light armor	Bonus
Electromesh Suit	+7 (5 + 2)

Medium armor	Bonus
Sith Battle Suit	+7 (3 + 4)
Electromesh Armor	+6 (2 + 4)

Heavy armor	Bonus
Flex Heavy Armor	+3 (0 + 3)
Felanar Armor	+4 (0 + 4)

Flexible Underlay Mark
I	II	III	IV	V
+1		+2		+3

Otherwise, dex mod is unrestricted when unarmored (unclothed, or wearing clothing or robes with no Max Dexterity Bonus specified).

Class

All classes except the Scout and Tech Specialist are granted a defense bonus which can increase on level up:

Classes	Feat	Level 1	Bonus
Soldier and Minion	Mandalorian Courage	0	2 * [ (Level + 1) / 6]
Scoundrel and Droid	Scoundrel's Luck or Logic Upgrade	2	2 * [ (Level + 1) / 6]
Jedi	Jedi Sense	2	2 * [Level / 6]
Jedi Master and Sith Lord	Prestige Sense	2	2 * [Level / 8]
Other Prestige classes	Greater Prestige Sense	2	2 * [Level / 5]

Although this bonus is normally attributed to a feat, it's entirely dependent on class: for example, Disciple, Handmaiden and Mandalore are all granted the same bonus as all are Soldiers, even though only Mandalore has the Mandalorian Courage feat.

Classes are granted this bonus at the following levels:

Class bonus	2	4	6	8	10	12	14	16	18
Soldier and Minion	5	11	17	23	29	35	41	47
Scoundrel and Droid	1	5	11	17	23	29	35	41	47
Jedi	1	6	12	18	24	30	36	42	48
Jedi Master and Sith Lord	1	8	16	24	32
Other Prestige classes	1	5	10	15	20	25	30	35

Although enemies normally only have class level 1, a defense bonus is added to any class bonus based on your main character level:

Set 1	Set 2	Set 3	Set 4	Set 5
rounddown(main * 0.6)	roundup(main * 0.7) - 1	rounddown(main * 0.8)	roundup(main * 0.9) - 1	main level

Some characters, like HK-47, are also granted a natural bonus.

Feats and effects

The Combat log 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	0
Critical Strike	-5

Force powers	Base	Improved	Master
Burst of Speed	Burst +2	Knight +4	Master +4
Force Aura	Aura +2	Shield +4	Armor +6
Slow	-2

Armor and other items can also have defense bonuses and penalties added to feats and effects:

Items		Value
Body	Robes	0 - +4
	Light armor	-1 - +3
	Medium armor	0 - +4
	Heavy armor	0 - +4
	Handmaiden's Robe	+3
	Atton's Ribbed Jacket	+4

	Bonded Plates Mark I-II	+(1-2)
	Bonded Plates Mark III-IV	+3
	Heavy Bonded Plates Mark I-III	+(2-4)
Ranged	Mandalorian Chamber Mark II	-2
Ranged	Mandalorian Chamber Mark I / III	-1
Melee	Advanced Zabrak Grip	-2
	(Superior) Zabrak Grip	-1
	Basket Hilt	+1
	Advanced / Superior Nagai Grip	+1
	Advanced / Superior Basket Hilt	+2
Lightsaber	Phobium Emitters	-3
	Refined Phobium Emitter	-1
	Disrupting Emitters	-1
	Improved / Expert Deflection Emitter	+1
	Fencing Emitter	+1
	Improved / Expert Fencing Emitter	+2
	Vibration Lenses	-1
	Lorrdian Gemstone	+2

Feats and effects from all of the above are restricted to maximum 10: for example, a Jedi using Master Speed (+4) and Force Armor (+6) with Ossus Keeper Robe (+1) and two Lightsabers with Expert Fencing Emitters (+2 each) 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, for that same Jedi 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).

The following are also added to feats and effects, but they are not restricted to maximum 10:

Feats	Rage	Fury	Frenzy
Wookiee Rage	-2	-4	-6

Force power	Base	Improved	Master
Fury	-2	-4	-6

Lightsaber forms

Lightsaber form	Defense	vs Current Target
Determination (Shii-Cho)	+3	-3
Resilience (Soresu)		+2
Aggression (Ataru)	-2	+5

Lightsaber form	Defense	vs Current Target
Perseverance (Shien)		-5
Moderation (Niman)	+1
Ferocity (Juyo)	-4	+2

Defense and Defense vs Current Target bonuses and penalties are cumulative:

Lightsaber Form	Determination (Shii-Cho)	Aggression (Ataru)	Ferocity (Juyo)
Defense vs Current Target	0 (+3 - 3)	+3 (-2 + 5)	-2 (-4 + 2)

Defense bonuses restricted by enemy damage type or alignment are added to feats and effects unrestricted:

Item		Restriction	Defense
Underlays	Durasteel Underlay Mark I-V	vs Bludgeoning, Piercing, Slashing	+(1-5)
Armband	Nomi's Armband	vs Dark Side	+1

Wisdom modifier is also added to feats and effects unrestricted for a male character with Battle Precognition, as long as he's not wearing anything with an armor value.

So feats and effects can exceed maximum 10 in these cases: for example, a Jedi using Master Speed (+4) and Force Armor (+6) with Ossus Keeper Robe (+1) and two Lightsabers with Expert Fencing Emitters (+2 each) and Moderation (Niman) lightsaber form (+1) receives a defense bonus of 11 (min(15, 10) + 1).

However, this also means that any subsequent penalties cannot be offset by any excess: for example, if that same Jedi uses Master Fury (-6) as well, the defense bonus is 5 (min(15, 10) + 1 - 6).

Any Dueling bonus is listed separately as feat:

Feat	Base	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

Being debilitated also means Dexterity modifier isn't added to defense or Reflex save (although Wisdom modifier can still be added to defense by Battle Precognition), 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.
