Ethereal Blade (Weavecraft)
Level: Mage 2
Mana: 20. Persistant. Base Success: 100%.
  By casting this spell, a wizard weaves the materiality of a specific object -- traditionally a dagger or sword -- into the tapestry of reality on a more fundamental level, making it capable of striking true against incorporeal creatures that dwell on the ethereal, astral or negative energy planes. The weapon effectively gains the Ghost Touch quality while the spell is active.
