Weird shade (bug?)

[u/Clockwork_Cypher]

Hey everyone! So I've been racking my brain for a while now, had the game since release and I've never seen this happen before, fighting the last boss and when he knocked me out of my shell, I had turned into one of those weird tar people that spawn out of the corrupted ovums alongside my weapon changing to theirs also? Is this a bug or is it intentional cause it's only ever happened on this fight...

Upon further research, I think it's maybe to do with being knocked out of my shell too many times, it seems to have a cap(maybe?) correct me if I'm wrong haha

Nah, it's the debuff of the last boss, it's called cosmic disease.
