Components:  V, S, M
Duration:  1 round per level
Casting Time:  6
Area of Effect:  Weapon touched
Saving Throw:  None

This spell imbues one weapon with a shimmering black radiance that makes it function as a weapon of vampiric regeneration for the spell duration. That is, one half of any damage inflicted by the weapon (including bonuses for Strength, magic, backstab multipliers, etc.) is gained by the wielder, rounded down.
The spell enchants the weapon, not a person, so the weapon may be used by the caster or another person, or even by several people in succession within the spell duration. For the purposes of this spell, a weapon is defined as any non-living object through which damage is inflicted. Common weapons like swords and staves are obviously included, but the spell could theoretically be used to enchant a pair of gloves to regenerate punching damage. In a case like this, only the permanent damage is counted for determining how many points are regenerated.
Hit points may be gained by the wielder above the normal maximum, and excess points are treated as in a vampiric touch (fades after one hour). The material component of this spell is a pinch of dust from a level draining undead (wraith, wight, spectre, vampire), which is sprinkled over the weapon to be affected.
