Daltim's Flaming Fist

You create a fiery fist that appears within range and can be directed by your will. The fist is the size of a human hand and lasts for the duration. It can be controlled to move up to 60 feet away from you, but always remains within range.

Once per round, you can use your action to direct the flaming fist to strike an enemy. Make a ranged spell attack against a target within range. On a hit, the target takes 2d6 fire damage and is engulfed in flames, suffering an additional 1d4 fire damage at the start of its next turn. If the attack misses, the damage is stored and added to the next successful hit. The fist can store up to 3 missed attack rolls worth of damage, which is released on the next successful strike. The fist can also interact with flammable objects, setting them alight unless the target succeeds on a Dexterity saving throw against your spell save DC.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the fire damage increases by 1d6 for each slot level above 4th.
