Heal Group transfers up to 75% of the caster's current hitpoints and distributes them among injured players that are standing within 1 square from the casting player (including players standing on the same spot as the caster). Players must have Accept Aid turned on to receive healing from this spell. As with all Lunar spells, the quest Lunar Diplomacy must be completed to cast this spell.
It is not possible to die from using this spell, as it will not work if the player has less than 11% health. This spell is able to heal other players in PvM single-way combat. It does not work, however, in single-way PvP. If affected injured players are missing a combined number of hitpoints greater than 75% of the caster's current hitpoints, it will heal evenly among them.
