The Life Leech is a magic weapon found in Blood and Blood II: The Chosen. It is a staff with a skull tied to the end that fires an ongoing stream of yellow fire and energy, causing explosions and spirit damage to the target.
The Life Leech occupies slot 9 and uses Trapped Souls (blue orbs with screaming faces) as energy. If the Life Leech hits a living target, it will add life to the player's, like a vampire. However, if the ammo runs out, the Life Leech will drain the player's own health for ammunition. Despite that, it's a useful and damaging weapon, especially using it's alt-fire as a secondary attacker. Victims who die from the Life Leech melt into a puddle of flesh.

The Life Leech returns, but instead of using Trapped Souls as ammo, it uses Focus, which is rechargeable. If the ammo runs out, the Life Leech will stop firing, without draining the player's health. Despite that it's a useful and damaging weapon.
