Create Bonfire

Duration: Concentration, up to 1 minute.
You create a 5-foot cube bonfire on ground you
can see within range. Any creature within the
bonfire when cast, or any creature that enters or
ends its turn in the bonfire makes a Dex save,
taking 1d8 fire damage on a failed save.
--- At Higher Levels: {dash}{dash}{dash}
This spell's damage increases by 1d8
when you reach levels 5, 11, and 17.
The bonfire ignites flammable objects,
provided they aren't being worn or carried.
