Lava Leap

You wreath yourself in molten stone and hurtle toward your enemy. Leap up to your Speed. At the end of your Leap, a wave of lava crashes onto all creatures in a 10-foot emanation. Each creature in the area takes (((your level − 4) ÷ 3, rounded down) + 1)d6 bludgeoning plus (((your level − 4) ÷ 3, rounded down) + 2)d6 fire damage, with a basic Reflex save against your class DC.

The cooling remains of the lava form a temporary protective shell around you, granting you a +2 circumstance bonus to AC until the start of your next turn.

Level (+3) Each type of damage increases by 1d6.
