Stat Restore Pot Share is a Lunar spell. When it is cast on any non-barbaric potion that restores (not boosts) stats which is in the caster's inventory, (doesn't work with Prayer renewal potion) it causes the caster to administer 1 dose of the potion to each player (up to 4 if used on a full vial; 6 if used on a full flask) in a 3x3 square area (including standing on the player's square) if they have Accept Aid turned on.
As with all Lunar spells, the quest Lunar Diplomacy must be completed to cast this spell. A hidden effect is that doses of potion are only used up on 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 it an invaluable spell for 2 person teams using Prayer or Super Restore potions. Players casting Stat Restore Pot Share purely to gain experience should cast the spell with only one other person so as to maximise the experience.
