Healing
Healing is a subelement of waterbending that allows the user to heal themselves or others, so long as they have access to liquid water.
While the server rule is that each user may only have one subelement, water is balanced such that Healing can coexist with Plant and Ice but not Blood. I.e., a Plantbender can Heal, an Icebender can Heal, but a Bloodbender cannot.
Abilities
HealingWaters
To use healing, the user must stand in water or hold water bottles with the HealingWaters slot bound. To heal themselves, they hold crouch. To heal another, they hold crouch and then right click the target.
Corrupt/Purify
These two moves have identical function and concern Spirits. All Spirits are categorised as either Light or Dark and are unable to switch between the two by themselves. Corrupt enables a waterbender to change a Light Spirit to Dark, and Purify enables one to change a Dark Spirit to Light.
Both moves have the same usage: the user holds crouch at a spirit target, who will be paralyzed while a blue double helix forms around them. When the move has sufficiently charged up, the waterbender will receive a message saying READY. If the user clicks now, then the spirit will change. Trying to use Purify on a Light Spirit or Corrupt on a Dark Spirit will paralyze them, but not change their status.
