Hello can anyone please help me, when i use frost nova on my mages frostbolt stops working on on the enemy target on all the mages apart from the leader.

Welcome to the forum & community.

First: Are you using ISBoxer or any other tool, like Hotkeynet?

Second: Can you show us how you did setup Frostnova?
Is it just on the normal quickbar and activated via 1 through ` or is it a separate mapped key?
