Create Bonfire

Casting Time: 1 action
Range: 60 ft.
Duration: Concentration, up to 1 minute.
You create a bonfire on ground that you can see
within range. Until the spell ends, the bonfire
fills a 5-ft. cube. Any creatures in the bonfire's
space when you cast the spell must succeed on a Dexterity saving throw or take 1d8 fire damage.
A creature must also make a saving throw when
it enters the bonfire's space for the first time
on a turn or ends its turn there.
