Value wont subtract by 200 when the player dies?

I recently made a transformation skill for one of my projects that I'm working on, when activated it plays sounds, inserts cool particle emitters into the player, and has some dialogue, as well as change walkspeed, health, and damage. The only problem is that when the damage is modified, it is suppose to be changed back to its original value when the transformation is turned off. It does go back to its original value when the transformation runs out of time, however the player can simply reset after they activate the skill and the damage will not return to its original value. I was wondering if I could counter this with an OnDied function, or maybe do something like

if Transform == true then plr.dmg.value = plr.dmg.value + number

You know? I'm not sure though. Here is the script, please tell me if there's anyway around this, and thanks for reading. This site has been really helpful lately, seriously, thank you ^^
