Life Steal

Life Steal

Your attacks have a x% chance to heal you for 1HP per hit. Each time you life steal 1 HP, you cannot life steal again for 0.1 second. Meaning the maximum possible life gained per second is 10. This means that high percentages of life steal have diminishing returns, as the chances of multiple instances of life stealing happening within the same 0.1 second drastically increases.

It also means that weapons that deliver multiple hits or pierces in an instant, such as shotguns, won't be healing more than 1 HP per shot, despite hitting many enemies.

If this is negative it acts like the stat is 0.

Extra projectiles, pellets, pierces and bounces trigger lifesteal.

Explosions do not trigger life steal.

Weapons in the Medical class have innate Life Steal, and some weapon classes have Life Steal bonuses (see Weapon Classes below).

Strategy

Life Steal is heavily dependant on your Attack Speed and a Weapon's cooldown. Weapons that attack quickly (such as SMG) will proc far more often than a slower weapon.

Vs. HP Regeneration

Compared to HP Regeneration:

• Life Steal can potentially offer much faster healing for less overall materials spent, by using weapons with fast cooldowns, Medical weapons, and a decent investment into Attack Speed.
• However, HP Regeneration is more reliable than Life Steal. It doesn't depend on your weapon speed, always procs, and it doesn't require you to hit anything. Especially melee users can get in trouble if they are put on low HP, and are forced to leave the melee range to flee. In this case, life steal stops healing you.
• Life Steal's cap of 10 HP/second means it has a hard limit on its healing capabilities, even at 100%. However, HP Regeneration takes over 100 to heal past 10HP/sec (see here), so this difference isn't noteworthy unless you're investing heavily into the stat.
