Ember

You hurl a ball of flame at a target within range. Make a ranged attack, doing 1d6 + Move fire damage on a successful hit. If the natural attack roll is 19 or 20, the target is burnt.

At Higher Levels: The damage dice roll for this move changes to 1d12 at level 5, 2d8 at level 10, and 4d6 at level 17.

Optional Rules:

Instead of a roll of 19 or higher, target makes a DEX save against your MOVE DC. On failure, the target is burnt.
