Create Bonfire

Duration: 1 minute, Concentration
You create a bonfire on ground that you can see
within range. The magic bonfire fills a 5 ft cube.
Any creature in the bonfire’s space when you
cast the spell makes a Dex save or takes 1d8 fire
damage. A creature must also make the save
when it moves into the bonfire’s space for the
first time on a turn or ends its turn there.
The spell’s damage increases by 1d8 when you
reach 5th level (2d8), 11th level (3d8), and 17th
level (4d8).
