Spirit Form - Witch

This spell confers upon the creature the ability to shift its body into a non-corporeal spirit form. In this form, the creature is of translucent and ghostly appearance, and can pass easily through walls, doors, or even solid ground at its normal movement rate.

The creature can walk right through hillsides or castle walls; however, it is deaf and blind while inside solid objects, so any lengthy journeys through solid matter are a matter of hit-and-miss. While the creature does not gain the power of flight, it can scale or descend any cliff at its normal movement rate, or will itself to ascend or descend up to 10 feet per round inside solid matter.

In spirit form, the creature ignores normal weapon or missile attacks, including physical hazards such as falling blocks of stone or pit traps. Magical weapons inflict half damage on the non-corporeal creature, and offensive spells are 30% effective (half this if a saving throw is made). The creature becomes vulnerable to spells that affect enchanted and non-corporeal beings. The non-corporeal creature inflicts no damage on corporeal creatures-unless armed with a magical weapon, in which cast it inflicts half normal damage with no Strength bonus. A spell-using creature can cast only 1st- and 2nd-level spells against corporeal foes.

The spirit form allows the creature to engage other non-corporeal creatures as if both were completely real and tangible to each other, so is useful in battling shadows, specters, wraiths, ghosts, or phasing monsters.

The creature can shift back and forth from corporeal to non-corporeal state for the entire spell duration, but it takes one full round to accomplish each transition.

The material component is a pinch of dirt from a ghost's grave.
