Was doing Ant Raids at one point where I encounter enemies with 1mil HP at wave 27 because I chose Strong Modifier III after that wave enemies HP reverts back 100k-400k+ ish HP(wave 30). There was also a time where I chose Strong V at Wave 30 and it Gave me Ant Boss with 88mil HP with enemies HP of 5mil. Another thing I think Harvest does not work I got One of it with 5 Negative debuffs ranging from III to V it only gave me 148 coins.
Anyways here's some photos and a 5min clip.
