Mercenaries Kadgar bug

I’m playing mercenaries and I have a mission with kadgar to do 250 arcane damage, I’m using a team of only arcane but my number doesn’t go up (kadgar is in the team). I completed 2 missions from blink fox and 2 for Millhouse, but my Kadgar mission doesn’t progress

Hello!
Multiple Khadgar tasks are bugged. The short answer is to use only UN-UPGRADED abilities, and have Khadgar do all the damage (or whatever progresses the task).
Here are some links to other posts about these task bugs.
