Describe the bug

While using ice crystal and Soulforged Steel armor, you can really utilize the leeching function with ice crystal.
Especially after applying unbreaking 3 to it with the true enchantment table.
Any time ice crystal damages an enemy, it triggers leech, which gives 1/2 a heart back.
This happens every time an enemy is damaged with it, and it can trigger multiple times with more enemies, meaning enemy hordes bunched up can become free hp.

To Reproduce

Equip soulforged steel armor.
Get damaged.
Use ice crystal on mobs.
Get stonks.

Expected behavior

Seems working as intended to me, but it's prolly way too strong.
Unsure how you'd change that without modifying leech itself, or the ice crystal itself.

Additional context

This seems to be an underlying issue with leech itself. As any damage dealt by the player will trigger it.
Ice crystal is usually pretty underpowered until unbreaking 3 is applied to it, after which it becomes a much more handy tool.
However I wouldn't say that ice crystal is overpowered with that by itself, as many things are immune, and it's an epic weapon boss drop as well.
