Mordenkainen's Lost Notebook
4-level Evocation
You cause a small hovering fist made of fire to appear
at a point you can see within range, which lasts for the
duration or until you cast this spell again. When you cast
this spell, you can make a melee spell attack against a
creature or object within 5 feet of the fist. On a hit, the
target takes fire damage equal to 2d8 + your spellcasting
ability modifier. If the fist hits an unattended flammable
object, the target catches on fire, taking 1d8 fire damage
at the start of each of your turns for the duration.
As a bonus action on each of your turns, you can move
the fist up to 20 feet and repeat the attack as described
above.
At higher levels: When you cast this spell using a spell
slot of 6th level or higher, the fire damage from the fist’s
attack increases by 1d8 for every two slot levels above
4th.
