Boost Potion Share can be cast on almost any non-barbaric potion in the caster's inventory. When cast, it causes the caster to administer 1 dose of the potion to up to four (if using a vial) or six players (if using a flask) 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".

The spell cannot be cast on Zamorak brew as this potion has the potential to kill a player and could presumably be used to make people lose their items.

The spell also cannot be used on a Saradomin brew presumably because it lowers players' offensive stats. That could be used to force players to leave a monster area due to significantly reduced offensive stats.

The spell cannot be used on a Combat potion.

Extreme potions cannot be shared with this spell, like all untradeable 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.
