Vulcan Bladework

You generate molten rocks to shape several searing-hot blades.
While the blades have the build of greatswords, they will impale the targets like spikes.

You can choose between 1-3 enemies to throw them at.
You roll 6d6 (1 target), 3d6 (2 targets) or 2d6 (3 targets) of fire-piercing damage.
If the target.s fail their Dex Save, they will be restrained and lose 1d4 of HP every turn.
