I tried this with Tumble and it works.
Easy way to find difference in address is: right click>change fade timer> 5000 (red change will stay for 5 second). After that, highlight the stuff that changes, get the offset address and freeze it.
CD hack doesn't work for buff effects but you can spam the skill.
Only problem is finding CE bypass so the game doesn't close after 5 minutes. Can you help me with that?
