Boss spawned with 100% hp when it should be when the spell was cast
Had this too. laughed my ass off because everyone was like whoa what and I was just sittin there like oops sorry guise
I hope it’s not intentional HAHA…
Yea it seems bugged - shouldn’t work on bosses at all 
it should spawn with the amount of hp the spell was cast on not 100% hp and its suppose to work on bosses with a low chance
