From Alter Aeon Wiki
Regeneration (often abbreviated regen) is a numeric stat that defines how quickly a character regains lost hit points, mana, and movement. The figure given is the amount a player will naturally recover over one tick.

Things that affect regeneration speed
- Young characters regenerate HP and movement more quickly
- Older characters regenerate mana more quickly
- HP Regen (Item Affect)
- Mana Regen (Item Affect)
- Move Regen (Item Affect)
- Resting in a room with a campfire, either placed by a builder or built with Firestarting, can provide a noticeable boost to increase mana and movement regen for lower level players without a dedicated regen set
- Even for players with a manaregen set a campfire can make up for the difference between resting and sleeping if you are in an area with aggressive enemies
- Sickness / Poison
- These reduce regeneration rates
- Room properties
- Certain rooms have healing or damaging properties; for example, a room filled with lava might have a large HP regeneration penalty applied to everything in it.
- Sitting down improves regeneration more than simple standing, and sleeping is even better.
- While in combat, your natural regeneration is much lower than outside of combat.
- Green demon familiar
- ebony-scaled demon familiar
- Certain minions may steal vital stats for you, such as draining mana.
- Regeneration spell
- Many players will create an equipment set designed specifically for regeneration.
- Summoning a green demon familiar will boost mana and movement regeneration; a ebony-scaled demon will increase health regeneration.
