Reason: "Mechanics specific to Pillars of Eternity II: Deadfire should be moved to Combat (Deadfire)"
The article covers all combat related mechanics. Pillars of Eternity uses a tactical real-time with pause system and a slow combat toggle that can be used with or in lieu of the pause feature. The player selects and commands one or more of his or her party members to issue orders, ranging from continuous activities, like making standard attacks, to the activation of limited-use tactical abilities, such as spells. Positioning your party and coordinating attacks and abilities is one of the keys to success.
All characters who are not moving and have melee weapons equipped project a small Melee Engagement radius around them. If an opponent enters that radius, they are instantly Engaged and stop moving, attempting to move any significant distance away from the attacker will provoke a Disengagement Attack.
- Disengagement Attack is a "free" action with no recovery time, has an inherent Accuracy bonus, does significantly more damage than a standard attack, and will call a hit reaction animation while momentarily stopping the retreating character's movement.
- Engagement radius is only a little more than a character width (barring special circumstances).
- Engagement limit is the number of opponents a combatant can engage simultaneously, and is usually one. If they don't have a target, it's the first enemy who enters the radius.
Actions take place in a real-time environment, which include repeated actions such as standard attacks, reloading/firing and one-off/special use actions, such as spell casting and item use. Selecting an action to perform will result in the character performing that action as soon as they are in range. Each action takes time to perform, as the relevant animation plays out and can be "interrupted". It is followed by a recovery time until the next action can be performed (movement simply pauses recovery time).
Certain Spells and abilities can speed up attacks/actions. Heavier armor hampers recovery time between actions, thus decreasing attack/action speed. Weapons have different attack speeds (and reload speeds, for crossbows and firearms), overall bringing to bear a Two-handed weapon takes more time than a fast one-handed one or using a magical implement. Additionally a character wielding two weapons is making more frequent attacks than one wielding one weapon (whether single-handed, two-handed, or with a shield).
When characters do something offensively (melee, ranged, spell etc.), you are always trying to hit and that always depends on your Accuracy vs. the target's defense(s), how effective your strike is determined by an attack roll. Successful attack may Interrupt the target Action and will result in an impact animation.
- Attack roll represents a character's attempts to strike an opponent. Each attack can result in Critical Hit, Hit, Graze or Miss, which will affect the attack damage or duration. The likelihood of each outcome is based on the difference between the attacker's accuracy vs target's defense values and can be further modified by various class abilities.
- Accuracy represents the measure of a character's chance to hit with any attack melee/ranged weapons, spells etc. It can be further modified by various class abilities and items.
- Defense represents how hard it is for opponents to land damaging blow on the character. There are four Defenses: Deflection, Fortitude, Reflex and Will. The higher a character's Defense, the more likely the opponent is to miss or only graze you. Defenses are determined by character attributes and class and are further modified by level, equipment, spells, abilities and talents.
Many activated abilities and talents indicate that they use either a full attack or a primary attack. The difference is only applicable when a character is dual-wielding two weapons, and determines how the activated skill performs its effect:
- Primary Attack: Skills using primary attack will only use the weapon in your main hand to perform their attack.
- Full Attack: Skills with full attack will always use both weapons (if two weapons are equipped). This effectively means that they will apply their effect twice.
Therefore, in general, primary attacks favor two-handed weapons, whereas full attacks favor dual-wielding, because full attacking with dual-wielding still benefits from a faster recovery than with a two-handed weapon, as well as two separate chances to hit (while it does mean you have to hit twice to achieve a similar damage as a two-handed weapon, it also means you have two chances to hit if all you care about is triggering some on-hit effect).
When a character lands a damaging blow, he or she deals damage according damage type vs Damage Threshold and affect the target's current Health and Endurance. Health loss occurs at the same time as Endurance loss and at the same rate. In previous builds health was reduced by a fraction of the endurance value (typically at a 1:4 ratio) and has since been changed.
- Damage Type: All damage dealt has a certain Damage type, affecting the efficiency of the target damage threshold.
- Damage Reduction (DR): The amount of damage that armor directly subtracts from each attack taken (after Damage Type calculations).
- Minimum Damage: No matter how high the DR a minimum amount (20%) of damage will get through armor.
The sequel changes the way damage is calculated and how protection works. The changes are as follows:
- Armor Rating: Replaces damage reduction and determines the damage done in conjunction with penetration.
- Penetration: Penetration mechanics affect the amount of damage done.
All relevant percentile (e.g. +XX%) damage bonuses that a character receives in Pillars of Eternity, whether from items, abilities or passive talents or any other source, are applied to the base damage of the attack being used. Here is a practical example using a character attacking an enemy with 10 DR with a two handed weapon:
- Damage Bonus: +30% (20 Might) + 45% (Superb Weapon) + 20% (Savage Attack) = +95%
- Base Damage: 14 to 20 damage (Two Handed Weapon)
- Modified Damage before DR: 14 to 20, *1.95 = 27.3 to 39 damage
- Modified Damage after DR: 27.3 to 39 damage, -10 = 17.3 to 29 damage
Flat Damage Modifiers
Abilities or items that add a flat number (e.g. +2 damage to unarmed attacks from the Sandals of the Forgotten Friar) will be added to modified damage before DR. However, in the case of +X flat damage to unarmed in Pillars of Eternity, the only percentile damage bonus that will apply to this portion of extra damage is the one received from Might e.g. if a Character has 20 Might (+30% Damage) and has a combined +10 damage to unarmed attacks this will become 13 damage (10*1.3 = 13). All ordinary damage modifiers will still apply to the base damage of the fists however â€“ extra +unarmed damage as affected by Might will be added on to this.
A lash that is applied to a weapon attack in Pillars of Eternity gives a multiplicative bonus to damage based on modified damage before DR. Lash damage is then calculated vs 1/4 of the enemy's damage reduction, regardless of the strength of the lash. For example, the Paladin's ability Flames of Devotion gives the Paladin an attack that does 50% Fire Lash damage. If we use the same example of a 2H weapon as described above in "Damage Resolution", except that it's a Paladin using Flames of Devotion, the Paladin rolls 30 Modified Damage before DR, the Weapon has a 25% Fire Lash, the Paladin has the Intense Flames Talent and the opponent has 10 DR we would end up with the following Damage:
- Modified Damage before DR: 30
- Modified Damage after DR: 30 - 10 = 20 damage
- Flames of Devotion (50% Lash): 30*0.5 vs 0.25 DR = 15 - 2.5 = 12.5 damage
- Weapon Lash (25% Lash): 30*0.25 vs 0.25 DR = 7.5 - 2.5 = 5 damage
- Intense Flames Talent (25% Lash): 30*0.25 vs 0.25 DR = 7.5 - 2.5 = 5 damage
- Total Damage: 20 + 12.5 + 5 + 5 = 42.5 damage
Lashes are completely unaffected by any damage penetration mechanics. For example, if the attack described above was carried out with the Vulnerable Attack Modal on (-5 DR), it would do 47.5 damage.
Lashes of an Elemental Nature (Fire, Ice, Lighting, Corrode) benefit from Elemental Talents under the Utility Talents section (Scion of Flame, Secrets of Rime, Heart of the Storm, Spirit of Decay respectively). The % of the lash will be increased by 1.2, such that a 25% lash becomes a 30% lash (25*1.2 = 30) and a 50% Lash becomes a 60% Lash (50*1.2 = 60). In the example used above, having the Talent Scion of Flame would have added an extra 6 damage.
As is evident from above, lashes work best with High Modified Damage before DR against opponents with low damage reduction. High modified damage before DR is achievable with high base damage attacks and a lot of %XX damage modifiers.
If a character is hit while performing an action such as casting a spell, attacking an enemy, reloading a weapon, or consuming a potion, a Concentration roll will occur and, if that roll fails, the action will be Interrupted. When an action is Interrupted, it is completely canceled and the character can take no other action for a specific period of time. This period is determined by the "Interrupt" stat of the item that caused the interruption (e.g., a weapon, a spell, etc.). If the interrupted action is one that can be performed only a limited number of times (e.g., a spell), the action is not permanently lost, but it must be manually restarted after the Interrupt period has elapsed. Conversely, unlimited actions (e.g., standard melee attacks) will automatically resume after the period has elapsed. Interrupting breaks engagement.
In Pillars of Eternity, all attacks have the chance to interrupt the target (with few exceptions), and can be directly countered with Concentration. Whenever a character is hit, the attacker's Interrupt stat is rolled against the defender's Concentration stat. If that roll fails (in the attacker's favor), the action will be Interrupted (see below for more info).
In Pillars of Eternity II: Deadfire, only some attacks (abilities or weapons) are capable of interrupting, usually given a particular hit event (i.e. Graze, Hit, or Crit). Unlike Pillars of Eternity, whether an attack interrupts or not is not based on chance or a stat comparison, and instead always occur on every attack unless countered with Concentration. When a character is hit with an Interrupt, their current action is lost, along with any resources (including Quick Items) they were using. If a character with Concentration is hit by an interrupt, they lose their Concentration, but are not interrupted.
Instead of being a direct stat comparison with a random factor (where the more concentration you have, the more likely you are to resist being interrupted on hit), Concentration is treated as a stacking status effect with a limited duration per stack. If a character has one or more concentration effects, they will negate an incoming interrupt entirely, removing the earliest added concentration.
Concentration helps you resist against interrupting attacks. If you cannot maintain Concentration, you will play a hit reaction and your current action (e.g., attack/reload/spell) will be Interrupted (as above).
In Pillars of Eternity, Concentration is primarily influenced by Resolve, but can be gained through talents and equipment. It is treated as a character stat, and has a direct influence on the likelyhood that you will be interrupted (more concentration means less interrupts). All characters have a base concentration of 75.
In Pillars of Eternity II: Deadfire, Concentration can be gained through Spells, Abilities, Talents, or Items to protect a character from being Interrupted. Each point of Concentration that a character possesses will prevent a single Interrupt effect from being applied to them, after which that Concentration point is removed. Concentration persists even if an ability's effect has run out, for example from a Fighter's Disciplined Barrage.
- Note: Pillars of Eternity only
If your Interrupt is high, your attacks have a greater chance of stopping an enemy's actions.
In Pillars of Eternity, a character's Interrupt score is primarily influenced by Perception, but can be gained through talents (e.g. Interrupting Blows) and equipment. Whether an attack actually interrupts or not comes down to a D100 roll, plus the attacker's Interrupt stat. If the attack is a critical hit, the roll is increased by 25. If the attack was a graze, the roll is decreased by 25. If the result is greater than the defender's Concentration, the attack successfully interrupts.
In Pillars of Eternity II: Deadfire, characters do not have an interrupt rating. Interrupts are instead always made for specific weapons and abilities depending on the outcome of a hit (Graze/Hit/Crit).
- Note: Pillars of Eternity only
Each weapon/attack has a time value that determines how long the interrupt (if successful) will last, during which the character may not take any actions. Attacks that have high rates of fire (like wands and spell missiles, or area of effect abilities) typically have low base interrupt times and vice versa. However, there are exceptions: Firearms have relatively low interrupt time (and high damage) and Thrust of Tattered Veils has a high base interrupt time (but does very little damage).
Each weapon or attack has a base interrupt time in one of the following categories:
These values can further be modified by magical weapons, items or the talent. Magical weapons can have a special property (called Superior Interruption) that bumps their set/listed Base Interrupt rating up by one category - e.g., a Stiletto would be set to Weak but be bumped to Average.
In Pillars of Eternity II: Deadfire, all interrupts last for 2 seconds, regardless of the weapon or ability used. This two seconds is added to the end of the current recovery time. Some interrupts will also knock the character prone for 1 second.
On "Story Time" difficulty, interrupts on enemies are increased by +50% in duration.
Endurance will be the tactical resource, expended and recovered quickly. If a character loses all Endurance during a fight, they are knocked out for the duration. Health is the long term strategic resource. Heal effects or spells are rare or non-existent, generally recoverable only by resting, so health has to be carefully managed over many fights.
Abnormal states that may affects a character's attributes or actions during combat. There is fairly big list of defined "afflictions" and the penalties they apply. The status effect and the damage of an attack will be checked separately. Some attacks simply have two separate components that succeed or fail independently of each other, but others will be “2-stage”. If the main attack at least scores a graze, the second attack will occur separately (and often against a separate defense).
