I can understand enemy bosses getting altered and having unique abilities/traits over the original and that’s not what confuses me but rather why a boss has a far weaker 3rd trait compared to it’s regular form.
This one in particular is Elemaugrim. Regular Elemaugrim’s 3rd trait reduces every enemies attack by 4 for each 4 or 5 match which is annoying but Eternal Elemaugrim’s 3rd trait is a single burn on 4 or 5 matches… why? Dungeon Elemaugrim’s ability burns everyone already so why add a pretty pointless 3rd trait?
If you want to argue with saying “It would make it too op” then what about Eternal Gard’s Avatar? He gets +4 armor per yellow match, far easier than needing to use abilities and his ability does true damage which makes it more threatening to the original Gard’s Avatar.
So yeah… I don’t see why Elemaugrim gets completely screwed over but Gard’s Avatar and other Eternal bosses gets a nice boost.
