Boost Potion Share can be cast on almost any non-barbaric potion in the caster's inventory. When cast, it causes the caster to use 1 dose of the potion for each person, up to four, in a 3x3 square area, including the middle square, if they have Accept Aid turned on. The player casting the spell will also be affected by the potion, although no additional dosage will be used. As with all Lunar spells, the quest Lunar Diplomacy must be completed to cast this spell.

The spell cannot be used in Castle Wars with the given reason that "You don't want to help your enemies". In addition, it cannot be used on any of the following potions:

Like its lower-level counterpart, Stat Restore Pot Share, this spell uses doses of potion only consumed by other players, not the caster. This means that if the caster has only 1 dose of potion, they will get the benefit as well as their target, effectively doubling the effectiveness of the potion, making potions such as Super strength potions more useful.
