Upon an unsuccessful save undead enemies will take the above as damage and the user will be healed for that amount.

1. Steal Life: Immediately drain the target's life force. The target takes 1d4 necrotic damage, and the caster gains half that amount in hit points rounded down. If the target dies or is dead, gain (1d4 + constitution modifier) additional hit points.  any HP over the casters maximum is added as temporary hit points to a maximum of half your total hit points rounded down.

2. Grant Life: Immediately supply the target with lifeforce. The caster takes 1d4 necrotic damage, and the target gains half that amount in hit points rounded down.

3. Combine Life: Combining the above two features, the caster stores the stolen lifeforce instead of absorbing it. The caster must use a bonus action to pass the stolen lifeforce on to another target creature within the next minute or absorb it yourself. If not, the life force dissipates. Attacks made against the caster requires you to pass a concentration check (WIS), or the effect ends. The caster does not take extra damage when transferring lifeforce this way.

necrotic damage increases by 2d4 every 5 levels
