High Level Alchemy (also known as high alch, hi alch or alching) is a non-combat spell used to convert items into coins at the best price a player could get from a specialty store. The amount of coins generated is normally 60% of the speciality shop price or 150% Low Level Alchemy prices.

High Level Alchemy is a popular way for mid and high level players to train their magic level, by buying or making valuable items and nature runes, then casting the spell on the items.

High (and Low) Alchemy can be cast on noted items, saving much withdrawal time from the bank, and simplifying the "click pattern".

Casting alchemy spells on stackable items will only alchemize one at a time.

It is possible to alch around 1,200 items per hour for a total of 78,000 magic experience.

Special cases

Some specialty shops may offer a higher price for certain items than the amount High Level Alchemy gives. For example, High Level Alchemy converts a gold necklace into 270 coins, but Grum's Gold Exchange in Port Sarim offers 315 if there are no gold necklace in the shop's stock. The price decreases 9 coins for each additional necklace in the shop inventory until it reaches a low limit of 45 coins when there are 30 or more necklaces. Some players sell up to about 11 items and then world switch to find another shop which has a low inventory.

On the other hand, the Armoury in the Warriors' Guild offers the same price as High Level Alchemy gives, and the buying price in the shop does not decrease as the inventory increases. Using High Level Alchemy on items tradeable at this shop is therefore only beneficial for gaining experience.

There are also three general stores which do buy at High Alchemy prices:
