Minecraft Dungeons:Regeneration

"If you avoid taking damage for 10 seconds, you will start regenerating health."

- In-game description

Regeneration is an enchantment that can be found exclusively on mobs and not available to heroes and consumable food within the various missions of Minecraft Dungeons. It is currently used only as the default effect of consumables.

Usage
Regeneration heals the health of mobs over time if they do not take damage for at least ten seconds.

Trivia

 * Despite being a mob-exclusive enchantment, it has an icon, an in-game description, and tiers, implying that it was originally going to be obtainable by heroes, but this idea was scrapped in favor of making it a mob-exclusive enchantment.
