Earth-Fire

 You raise three Motes of Earth up from a 5ft square of ground within a 10ft radius of yourself, the motes turn to burning molten Lava as you shoot them at targets within range. You can shoot them at one target or several. Make a Ranged Spell Attack for each Mote of Earth-Fire. On a hit, the target takes (2d6)+SM Fire damage and (1d6) Bludgeoning damage and the target becomes Scorched.

Scorched: A creature with a Stack of Scorched takes (1d6)+SM Fire damage at the start of their turn for every stack they have. At the end of their turn the number of stacks is reduced by 1 until none remain, unless more stacks of Scorched are applied. If a target ever gains 5xStacks of Scorched, they trigger an Ignition: the target explodes and deals (5d10)+SM of Fire damage to themselves and other enemies within a 10ft Radius on a failed DEX Save. DC equal to your Spell Save DC.

*SM=Spellcasting Modifier. 

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you create one additional mote of Earth-Fire for each slot level above 2nd.
