Working On Completion for Hearthstone. and while starting and doing mercenaries now that it wont have additional things added. I have found that some characters have issues with reading task completions ((Khadgar being my Primary issue)) Task 8: Deal 250 Arcane Damage. I did a millhouse + cookie set up too get too 80 Arcane Damage per hit, filled opponent board with swordfish and then did arcane explosion ((which was 80dmg x 6 enemies which would be 320 damage)) and it didnt complete. I also tried triple golden monkey from elise, too empower khadgars arcane shot too deal 374 dmg ((4 monkey setup)) and it STILL didn’t complete even when khadgar did the 250 arcane damage so I came here. I know its not getting extra things but I hope theres still bug and technical support for the game mode.
Hello! The abilities must be un-upgraded in order to count for the task completion. Yes, this is a bug. You may find these other posts helpful, as the same thing happens for other tasks as well.
