Been a while sense I've been there but yeah now that I think of it, in funhouse the mages and/or hammers produce effects ("hahaha" or sumth), and possibly chests and/or falling anvils.
Anvils in maps are triggered by the 1st person @ a set location, or fall in pattern with gustav.
Both are avoidable.
When it was first released nuris was way op with mobs having a couple ways to one shot well geared ppl, and bosses who could reset/full heal randomly often. They still have all the same attacks but they're nerfed, just numerously noticeable.
Only comparison now is the way mobs in the caverns maps, or yetis in humania can kill you b4 you say

"What happe..."
