Alchemy is the process of turning one object into another, and in RuneScape, is used for turning base items into coins, metal bars, food, and other resources.

Normal Spells

All alchemy spells from the Standard spells use nature runes to convert an item into a different item.

High Level Alchemy

High Level Alchemy is by far the most well-known and used alchemy spell. It is commonly used to fill "dead time" between or before activities, in addition to the more focused uses described below.

Alchemist's Playground

The Alchemist's Playground is a magic based activity based around the concept of alchemy spells, situated in the Mage Training Arena north of the Duel Arena. Players have to use High Level Alchemy or Low Level Alchemy spells to convert items in eight cupboards to gold coins in an attempt to earn pizazz points which can be traded for certain rewards.

Use for Profit

Although alchemy spells can convert items into gold, it is very difficult, if not impossible, to turn a profit by buying and alching items. The market price of most commonly alchemized items is usually slightly lower than the respective high alchemy values, but not low enough to offset the cost of the nature rune required to cast the spell. Regardless, high level alchemy remains one of the most common methods of training magic, because it can be cast on noted items without interfering with training or having to bank.

Players often bring runes for high alchemy when killing monsters, in order to alch some of the items dropped and free up inventory space for valuable items with low alchemy values (such as herbs and uncut gems).

Lunar Spells

All Alchemy spells in the Lunar Spellbook use Astral runes to convert an item into a different item.
