Bone Sword (Immortal Magic)

Basic Discipline: Hells

You form energy from the Lower Planes into a powerful weapon. This weapon can take the form of any blade, but it must be a sword, and its properties don't change. Only you and anyone else you choose can wield this weapon.

The weapon is melee with a reach of 5 feet. It does 1d10 + your spellcasting ability modifier slashing damage on a hit, and uses your spellcasting ability modifier for to hit rolls.

The weapon lasts until the spell ends, upon which it disappears in a flash of orange light.
