Anyone have any idea how much damage a fire should do?

The brightmage in our group is very keen to use Pyrokinesis to move a bonfire onto the enemy and roast them alive!

Opposed agility check probably. Then initial damage for a bonfire would be 5 and a torch would be 1 with ongoing Condition: ON FIRE!

Condition: ON FIRE! (3) recharge tokens (Brief) - 5.
