Is a way to lifesteal?

Is there a class, feat, spell or item that lets you increase your life by hitting stuff is what Im basically asking.

[SoulDecay]

There are items with Vamprism (dunno how it works, I'm not that high level, but I've seen some screenshots.) and the Bodyfeeder prefix (On crit, gain 15 temp HP for 1 minute.)

[Thanimal]

There's a weapon attribute called Bodyfeeder.

In some cases it can be excellent -- especially in an off-hand on a high crit range weapon (e.g. Kukri) when soloing with a TWF melee.

There is the Demon Queen khopesh which has lesser vampirism on it. Otherwise you're going with the nearest equivalent such as a bodyfeeder weapon. Bodyfeeder kukris, rapiers and scimitars work very well. Or you roll a monk with fists of light and use that all the time, or make sure there is one in your party.

Monk Fist of Light attack puts a Curse of Healing on enemies that heals people for 1 to 2 points as they melee the target.

A few select items, such as the Chaosblade from DQ and the new Kama from Mindsunderer have a mod called lesser vampirism, which lets you leech a couple hit points per hit.

Also, the monk path of light has fists of healing, that lets the entire party regain a couple points of HP per hit they land on whatever you use the finisher on.
