Summon Wildfire Spirit

Action: you can expend one use of your Wild Shape feature to summon your wildfire spirit.
It appears in an unoccupied space of your choice
that you can see within 30 feet of you. Each creature within 10 feet of the spirit (other than you) when it appears must succeed on a Dexterity saving throw
against your spell save DC or take 2d6 fire damage.
