**TESTED**
Do not waste your time with this mod, as much as I appreciate the thought & the work put into it, unfortunately it is purely client sided.
If your character is not strong enough to beat a boss, and you beat the boss/player with the x100 damage or immunity, it will simply give you an error and you would of lost the fight.
This mod gives you absolutely no advantage whatsoever, everything is purely client sided, and as such you won't be able to one shot anything or have immunity because the server recognises you got killed / you can't kill that boss/player with your current stats and as such it fails the fight for you regardless what you see on your screen.
All this mod is going to do is get you banned, with 0 advantages, nothing works at all, everything client sided.
