High Level Alchemy

High Level Alchemy (high alch, hi alch or alching) is a non-combat spell used to convert items into coins at the best price player could get from a specialty store. The amount of coins generated is normally 50% more than the general store or Low Level Alchemy gives.

High Level Alchemy is a popular way for mid and high level mages 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; on RuneScape Classic, it alchemizes the entire stack at once.

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 tradable at this shop is therefore only beneficial for gaining experience.

There are also three general stores which do buy at High Alchemy prices:
 * Bandit Camp, free-to-play, mid Wilderness
 * West Ardougne, members only, need to have started Plague City
 * Rogue's Den, members only, level 50 Thieving and Agility required
 * All stores on Karamja while wearing Karamja gloves 3
