Peach

Peaches are made by players through the use of the Bones to Peaches spell, which may be purchased at the Mage Training Arena. When cast, the spell converts each set of bones in a player's inventory into a Peach. Each Peach heals 8 Hitpoints when eaten, which makes the spell Bones to Peaches a very useful resource whilst training combat in remote areas. It is much more effective than the level 21 spell Bones to Bananas, which produces Bananas which heal 2 Hitpoints. Jagex has made it so that peaches are non tradable to stop scammers. There is also a rumor that Andrew Gower's favourite fruit is a peach, which was why he introuduced it in the game.

Peaches are the cheapest food in the game:

$$two-natures = 2 * 270 = 540$$ $$1-spell-produces-27-peaches = 27 * 8 = 216hitpoints$$ $$540(coins) / 216(hitpoints) = 2.5(coins-per-hitpoint)$$

Being cheap and lightweight, the Peach is considered by many to be a very effective option when training for extended periods of time on Non-player characters which drop bones. Players willing to spend more money may also consider investing in Guthan's armour for more versatility.

Peaches are handy in many locations, for example Dust devils or Bloodveld that are far away from a bank and are not suitable for the use of Guthan's armour - and which drop bones 100% of the time.

If you alchemy it you will not get any coins.
