This next one should be fairly simple, since it would appear to fit nicely between the lich and demilich templates.
Semi-Lich
This is a demi-lich that hasn't made it yet. Its appearance is similar to a demilich, a gem encrusted skull and a few scattered bones. Although its body has rotted away, its original lifeforce is still strong, and the creature does not need to accumulate energy as does a demilich. When approached to within 10 feet, the skull rises into the air, supported by a column of dust. The creature can use any spell it could use as a lich, but has no physical attacks (except touch-delivered spells). The creature cannot be turned. Even if reduced to 0 hit points or less, a semi-lich is not destroyed until holy water is poured on the site and a ceremony spell is cast to consecrate the ground. If these steps are not taken, the creature will reform in 1d6 months.
This particular specimen is a 13th level cleric with a wisdom of 12.
