Lifesteal enchantment - unitx/lifesteal GitHub Wiki

An extra feature in this add-on is the lifesteal enchantment, which has 8.3% to spawn in an ancient city chest and a 22.5% chance of dropping from an ominous vault. To apply the enchantment, drop it on top of an axe, and it will be applied.

Then whenever you deal damage with an item with this enchantment you will have a small chance of regenerating health, as always it is fully customizable in the settings.
