DAMAGE STATS
Armor Penetration
This stat allows the attacker to ignore a portion of the target’s armor when dealing damage. AP can be either a flat amount or a percentage. Neither type of AP can reduce a target’s armor below zero. Reduction is made on a one-to-one basis, with flat amounts being calculated before percentage.
Attack Speed
Attack speed is how fast you attack with your primary weapon. Attack speed can be increased by talents, artifacts and tactical items. Attack speed does not affect abilities (those are affected by cooldown reduction). Attack speed cannot reduce a weapon below 25% of its original speed.
Critical Hit Chance
Critical hits allow your weapon attacks to do more damage than normal. Critical hit chance is the percentage change for you to land a critical hit. All immortals begin with zero chance of this happening. Critical hit chance can be increased via talents, artifacts and tactical items. Your critical hit damage stat determines how much extra damage you do when you manage to land a critical hit. Critical hit chance caps at 80%.
Critical Hit Damage
Once you land a critical hit, this stat determines how much extra damage you do. The default value for all immortals is 100% (i.e. double normal weapon damage). The stat pane in the game does not show this since it is standard; the pane shows any additional percentage you have above this amount. So if your critical hit damage shows 25%, it means your weapon will do 125% additional damage (or 2.5 times damage) when you crit.
Damage Types
The type of damage dealt to the enemy; the damage type determines which mitigation type to use to defend against it. Each Immortal uses two of these damage types (one weapon type, one ability type). There are five damage types…
Magical Weapon Damage
Only found on base weapon attacks; it can be modified by items, talents and artifacts. The mitigation stat is Magic Resistance.
Magical Ability Damage
A form of magic damage inflicted only by abilities. This stat can usually only be modified by talents or artifacts. The mitigation stat is Magic Resistance.
Physical Weapon Damage
Only found on base weapon attacks; it can be modified by items, talents and artifacts. The mitigation stat is Armor.
Physical Ability Damage
A form of physical damage inflicted only by abilities. This stat can usually only be modified by talents or artifacts. The mitigation stat is Armor.
True Damage
This damage type is only used by certain abilities, non-player creeps and neutrals, or bosses in PvE battles. True Damage cannot be modified or mitigated by any means.
Dodge Penetration
This stat allows the attacker to reduce the target’s chance to dodge a weapon attack. Each 1% of DP reduces the dodge chance by an equal 1%. DP is always a percentage. Though DP is not capped, Dodge is capped at 30% so it is not generally practical to raise DP any higher than that.
Magic Resistance Penetration
This stat allows the attacker to ignore a portion of the target’s magic resistance when dealing damage. MRP can be either a flat amount or a percentage. Neither type of MRP can reduce a target’s magic resistance below zero. Reduction is made on a one-to-one basis, with flat amounts being calculated before percentage.
