Bone Leech

When cast upon a creature, bone leech causes the very minerals which make up bone to dissipate. Essentially, the caster is making the victim's bones brittle and much more susceptible to bludgeoning attacks.

The victim of the spell suffers an additional 1D6+1 per level points of damage from any bludgeoning attack (including hand to hand combat). Wrestling becomes quite hazardous with a 25% chance per round that a bone will be broken causing 1D8 points of damage. Also, he will suffer double damage from any fall greater than 15 feet. The unfortunate may make a saving throw to negate the effects completely.
