Level: Lantern 9
Spell Resistance: No
Summoning you from your weapon and Leaping into the air, you pull out your lantern and drop it on your enemy as the two of you slash through it. The ground ignites in the shape of a massive X and explodes in a nuclear explosion. Make a single attack against an enemy within reach. If this attack hits you deal double damage, and apply any critical hit feats to the attack that you can. The creature must make a fortitude saving throw DC: 19+Strength modifier or take an additional 1d8 damage per level (Max 20d8). Creatures who fail this saving throw are knocked prone and gain a vulnerability to fire until the end of your next round. Creatures that succeed take 1/2 of the additional damage.
