Priest weapon sometimes does 0-1 damage

[Lmno_]

So when i'm using my priest character (Support) i sometimes get this bug where when i'm fighting i start doing 0 damage and i have to run away and drop my weapon, move it to another slot, do alot of random things until it starts working again. can i please get some help with this as it's been getting really annoying over the last few days. thanks.

Try to relog.

This occasionally happens to lower leveled characters, from personal experience, I believe that it is caused by you taking damage from a mob, when this happens, the only way I found to resolve this ingame was to deal magic damage to a mob, instead of the normal basic attacks.
