No you don't need a script (and if you did, it wouldn't go into the "questions that don't deserve their own thread" thread).
If your final boss is evented, you can do a Continue When Loser, and get the If Win / If Lose options. Choose a variable to count how many times the skill is used, and set it to 0 right before the battle processing call.
On the skill's damage formula, add 1 to the variable if the enemy has the appropriate state.
