Biscuits

Biscuits are a stackable food item released with the 4 August 2010 Treasure Trails update. They are available from any level Treasure Trail. They will heal 10-30 lifepoints, and will restore 1 Prayer Point. These are not tradeable, and are only obtainable through Treasure Trails.

Biscuits are an upgraded version of the Purple sweets which also heal 10-30 life points and are stackable. However, they do not restore prayer points and are not tradable.

This item would be very useful in places such as the fight caves; however, they are untradeable and can only be received from clues. A lot of these would be needed to replace a single prayer potion: they restore 1 prayer point each. For example, at 80 prayer, 108 biscuits would be needed to replace a Prayer potion (4) or a Super restore (4).

In the Items Kept on Death menu, biscuits are shown to be worth 3000 coins each.

Trivia

 * Biscuits usually come in stacks of 2-30.
 * Biscuits and Jangerberries are the only food in Runescape that restore Prayer.
 * Biscuits and Purple Sweets are the only two foods that are stackable.
 * Since the biscuits can stack, they heal the most life points per inventory slot, together with Purple sweets, limited only by the amount the player has and the 2,147,483,647 limit of items you can have. 2,147,483,647 Biscuits means you can heal: 21,474,836,470 to 64,424,509,410 life points.
 * Biscuits are also known as rune rusks.
 * Biscuits have little symbols of Saradomin, Guthix and Zamorak on them. This explains why they are able to restore prayer points.
