You do realize that its not just about the defender? Node input would help
Thing should work for that fight since he is nullify immune. Depending on your hacks angela and herc will just feed his regen. I've never fought one till last reset and I had to quit out of room 16. @BringPopcorn there are no nodes other than the global which is probably just increased health or attack. No orange extra nodes in the pic above.
If thing didn't work then quit out and avoid mystic deadploids in the future lol
I use ageon or herc...what I did was chip away his health...once he starts regen, I quit the fight and start the same process again until he is dead...
He has a chance to copy it aint a nullify so if thing gets buffs of the list he can copy then he can regen think of it like rogue
