Mamu is one of the best but only with his Icefang and Tusk Gore, Enemies can't really buff themselves anymore thanks to him. Then there's Nessa which seems pretty good, i always choose Thermals and Collapse, it's an instant proc, and eventually it just keeps healing and losing hp so it never goes into egg form, i gotta try the other abilities for Nessa ig
(realizes thermals can be good) Thaaaaaaats why it becomes so much stronger when I radiate it, I usually pick susceptibility and nova, but collapse and thermals is actually a lot stronger, gonna try that on my calamity run, I have beaten the other four on standard using nessa, and I think egg will be helpful with the you lose=you die
Yeah Radiating Nessa is great cause now her Nova heals a lot more, and technically speaking 2 other monsters, and with susceptible stack the rejuvinating flames damage might be extended, but i'm not too sure about that. I also personally radiate Slaag, tuskal, Gora, Skimander, Gheist Tizik and Parra, aside from Nessa now. Woad only when it's supposed to be the main gimmick monster on my team.
