Ai electric zap

Whats with the electric zap ai mages use? It seems completely unblockable and goes through some objects. It stuns you for a few seconds, and when you’re surrounded by multiple melee guys its devastating. I find it more frustrating than difficult. It loads fast and shoots fast and seems unblockable and any weapon in the way just gets imbued.

Genuinely lost my cool when i got stunned by it and got stabbed like fucking caesar by 4 dudes whilst stun locked. Wtf do u do against this just pray??
