Faerie

The Faerie is a passive entity added by Dissolution. They appear in forest type biomes. If you are in a fully healthy human body, collecting one (by approaching her like an experience orb) will result in her offering you a regeneration effect. If you are an undead, this will trigger the Purification effect, a buff that gradually converts back your undead body to a normal alive body. After operating, Faeries will become weak. In this state, they are unable to do anything, and will take the time to regain their abilities.
