wait i don't seem to understand, he is asking for crit-trigger of effect that triggers when crit procs?
sry you may be right but i dont understand . . my english is bad and i dont know very much about world editor . .The event of the trigger depends on what you want to crit for. Then use a Random Integer with a large range, and check it against a smaller range of values for the chance.
how do i trigger it? because usually if i want to trigger spells i just make "a unit starts casting an abillity " but crit is a passive do i have to use "a unit starts the effect of an abillity" ?If you want to do extra stuff when a crit procs, you still need to trigger it. There's no way to simply detect when it will proc.
