Heal Other transfers up to 75% of the caster's current life points, to the targeted player. The targeted player must have Accept Aid turned on to be healed by this spell. As with all Lunar spells, the quest Lunar Diplomacy must be completed to cast this spell. There is a glitch that occurs allowing you to transfer LP to an opponent who is dead. This will not stop them dying, but the casting player will still lose 75% of their life points. Additionally, a player needs at least 11% of his or her life points to cast this spell. Some players may choose to use this spell as a method of training magic in tandem with another player. One player would cast the spell on another, who would then cast it on them, resulting in a constant transfer of lifepoints and rapid gain of magic experience. The downside to this sort of the training is the great expense required for the runes. It is also very useful in PVP, but can only be cast in multi-combat areas. The icon of the spell was originally red.

Smiddi Ryak can cast this spell in Temple Trekking, provided she is progressed to at least level 92.

Heal Other costs 1103 coins for each cast. Wielding a law staff reduces the average cost to 1050.5 coins.
