I'm in a side node fighting Maggia. I have Dr Strange who's Flames of the Faltine say they do 18k damage when an enemy power fires. I also have 10 AP in Scarlett Witch's Chaos Magic power, which should add 50% damage. Instead, when the Maggia fires a power, I deal 6k damage.
If the Heroic nodes have a damage nerf, you should say that in the event rules. Otherwise, this is just a bug.
