Dagger of Draining

This dagger can hold up to 3 changes. The charges replenish at a rate of 1 per monster kill. The CR level of the monster must be at least 1. The dagger must get the killing blow on the monster for it to regain a charge. Once attuned each charge can be used to regain 1d4 + the CR level of the monster killed in hit points. Only the one attuned to the dagger can benefit from the use of charges. The hit points are considered temporary hit point if the wielder of the weapon is at max hit points. The dagger is a triblade design with a blood channel along the spine of each blade that runs through the handle. On the pommel of the handle is a pale green gem that is being held in place by the legs of a spider. The blade itself is black with the handle being wrapped in a thick black scaled hide.
