Ghostly Resonance

Your runes don't just draw power from the world of the spirits—they can let even the most mundane objects harm spirits as well. When you etch or trace a divine or occult rune on a weapon or creature, you can grant it the Ghost Touch weapon property rune. For a weapon, this doesn't count toward the weapon's limit on property runes. For a creature, the rune applies to all unarmed Strikes the creature makes. This benefit lasts as long as the rune remains.
