Rotations and damage per second
The game has no damage-per-second formula, and no code in it adds up a rotation. So this wiki gives no damage-per-second number for a spell or a build.
A number like that would depend on things the files do not fix: how fast you press keys, how many enemies stand in an area, how long a target stays in range, and how often your hits land.
The files do fix the rule for one hit, the cooldowns and the stacks. Those pages are to the right.
