This not bug but more to false description

See there "Unable to use after Round 2"

and the skill scroll taht i use is the one taht active on round 4th.

enable mean man something possible to do or active something.

and i think unable is the opposite. So this description mean i cannot use this skill after round 2 when the truth is i c*e it on round 4 or after round 3 end.

So this one false in a number of rounds and the unable word.
