What is this attack???

[TastyBunny]

Been trying to hunt in kitchicor forest and died twice by this

I think it is some kind of spell??? Becuase it happend after skeleton cast something on me. Then I just start walking in the same place and can't do anything. there was no Spell icon on the buff/debuff tray.

what is this and how can I prevent it??? Im necro btw

Thanks in advance!
