Arcane Edge

Arcane Edge: Beginning at 2nd level, you know how to make your strikes as explosive as a fireball. Once per round, you can use a 1st level spell slot deal an extra 3d6 damage to one creature you hit with an attack. The attack must use a finesse or a ranged weapon. The damage increases by an additional 2d6 for each additional slot level above 1st . This damage can be any damage type the Spellshadow is capable of casting.
