Hit life leech

From UOGuide

Hit Life Leech is a weapon property that was introduced with Ultima Online: Age of Shadows.

It gives an attacker the ability to leech Hit Points from his opponent every time he successfully delivers a hit.

Hit Life Leech intensities on weapons

The maximum possible life leech percentage you can get on a weapon is determined by the following formula:

For archery weapons divide those values by 2.

The formula is based on this post by MrTact on UO Stratics.

Amount of Hit Points leeched

On every successful hit you will leech 0 to X percent mana of (Damage done * 0.4) - X being the Hit Life Leech value on your weapon
