Action speed describes how fast skill is used and is calculated as uses per second. Next use of skill can be performed after cast time end. Action speed describes the overall speed at which an actor (a character or monster) performs actions, such as moving, attacking, casting, placing totems, throwing traps, or using mines. In passive tree actions speed are defined as movement speed, attack speed, cast speed, placement speed, throwing speed (mine throwing speed and trap throwing speed) and etc. Action speed can be considered a multiplier for stats that affect the speed of individual actions, though it does not directly modify those stats. Modifiers to action speed can be found under the Defense tab on the character's stat sheet, but it is only visible when it is modified in some way.
Calculating enemy Action Speed Math
- All modifiers that say Enemies have % reduced Action Speed are calculated as Enemies have % less Action Speed instead..
- Some monsters have a minimum action speed %. This prevents them from ever reaching zero action speed.
