Arelith

I am not sure if this is a bug or an intended design, but I fought what seemed to be a stone-golem-shaped person [a druid?] at PGGC and could not damage him. He had more than 800 HP, was immune to sneak and critical attacks and absorbed 30-40+ damage each hit, while hitting stronger than barbarians do and knocking people down with ease. He also seemed to be unaffected by most negative effects, clearly invincible to most builds. What was concerning is that his form could neither be dispelled nor affected by the anti-magic field at all, which looked very unintended to me.

They can be beaten...but they are a very good pvp build! I don't think this is a bug. We've tested the potency of this kind of build IC by sparring in arenas. It eventually lost to a certain bard, and a fighter/wm/lm build (not simultaneously but two separate 1v1s), but was definitely a close match.

Hard counter is that you just run a damage shield. They're literally incapable of breaching you.
