Faerie

The Faerie is a passive entity added by Dissolution. She appears in forest type biomes. If the player is living, interacting with one by approaching her will result in it giving the player the Regeneration status effect. If the player is undead, this will trigger the Purification effect, a buff that gradually converts the player into a living being. After interacting with players, Faeries will become weak—in this state, they are unable to do anything, and will take the time to regain their abilities.
