Lifesteal Enchant
A balanced modification that allows you to absorb health from enemies and restore your own! All this with just one enchantment.
Oh no! I'm low on health!

Never mind

How is life steal calculated?
y+=0.15 * (x+z)
Where:
y = player health
x = enchantment level
z = weapon damage
This formula allows scaling the amount of health returned not only depending on the level of the life steal enchantment, but also on any damage increase effects the player may have, or weapon damage enhancers.
