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[1][2]. 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), 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.
