Wildfire
An Exceptional Aura of itinerant ignition
Conjure Wildfire atop a single site nearby. At the end of each turn, each unit here takes 3 damage, then move Wildfire to an adjacent location it hasn't visited before. If none remain, dispel Wildfire.

FAQs
Q: Does “visited before” apply to other Wildfires I cast in the same game?
Once it leaves play, a Wildfire forgets all the places it visited. If you have multiple Wildfires in play, track them each separately.
