FALLEN ONE SKILL PROBLEM

Okay, I got the skill working pretty flawlessly except for one thing...it repeats itself twice when an enemy uses it and I HAVE NO IDEA WHY. I'm going to paste the code below and its a LONG image graphic, so scroll through to see it all. As for the nature of the problem, it usually goes like this: The enemy casts it, a switch is turned on to activate a battle event page, you get a wait on each character as the animation of the skill 'attacks' them, then you get the damage done and if Sasha is in the party, a chance to increase the skill viewings to potentially learn the skill. It all works...except the final part, the switch turning the damn skill off! On ANY character's NEXT turn, the skill REPEATS itself, does damage a SECOND TIME and THEN it finally decides to want to turn off the switch which activated the battle event in the first place. It occurs the same way every single time. Why? What's the fix?
