High Level Alchemy


 * For a lower level version of this spell, see Low 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 a player could get from a speciality store. The amount of coins generated is normally 50% more than the general store or Low 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. For example, a player might buy or make, yew longbows and cast High Level Alchemy on it. In this case, the player may consume approximately 290 coins per bow, or if they made them, make a profit. For Free Players, it is suggested that they High Alchemise Rune Square shields or  adamant platebodies, as the total loss in coins for runes and Shield combined is only around 30 coins for the adamant platebody, and 75 coins for the Rune Square shields.

High Alchemy takes 5 game ticks, or about 3.0 seconds, to cast. It can be cast up to about 1185 times in one hour, although in practice many people only cast it 900-1100 times per hour. Players should note that the time it takes to cast High Alchemy is slightly faster than the time it takes for a Gnome Guard with a halberd to attack. This and the fact that they rarely ever hit more than 2, makes this a great method for the players who cannot seem to get the timing correct. There are many more monsters you could use as a timing tool, however a Gnome Guard wielding a halberd seems to be the best. People who are members may like to high alch their items in the minigame Castle Wars because the 20 minute time limit provides a reasonable amount of measurement. It can also be enjoyable for the players to watch others fight.

Another reasonable measurement is the time in between in which the buzzing sound effect finishes but the graphics does not. In this time, you can seem to get the fastest repetition of the spell.

High (and Low) Alchemy can be cast on noted items, saving much withdrawal time from the bank, and simplifying the "click pattern". Also, it should be noted that High Alchemy only grants 65 experience, regardless of the rarity or expensiveness of the item you are alchemising. For example, high alch-ing a Bronze pickaxe grants no less experience than high-alching a Dragon dagger!

In practice, a player might prefer training High Level Alchemy by buying items from other players, which usually results in more coins being created than paid for the converted item. This is widely regarded as a major cause of inflation in the game.

Some items, such as rares, are worth far more on the street than in the store. As such, players are advised not to carry any rare items in their inventory, as accidental alchemising would cause a major loss for the player.

Casting alchemy spells on stackable items will only alchemise one at a time; on RuneScape Classic, it alchemises the entire stack at once.

Note that it is generally not profitable to buy both the object and nature runes. The player should make either the nature runes (from pure essence) or the item in order to make a profit (making both will obviously give a larger profit). However, there are some instances in which about 40 coins can be made from this process: alching worn out Dharok's platebody or worn out Torag's platebody will yield 280 coins more than the buying price, covering the cost of runes and leaving a bit more. However, this does take some time if the player does not have large quantities of money with them; as such, there are various other items which have this small profit attached (the most Jagex will allow).

During the week of 4 April 2008, Jagex altered the way High Level Alchemy and Low Level Alchemy function so as to render them inoperable while standing inside the Barrows crypt areas.

MouseKeys
One option to reduce the effort when using High Alchemy on hundreds or thousands of items in a session is to enable an accessibility feature of Microsoft Windows called MouseKeys. This allows the '5' key on the number pad to be used as a substitute for clicking the left mouse button. To enable the feature on Windows XP (also works on Vista) hold down the Left Shift, Left Alt and Numlock keys simultaneously to show the MouseKeys dialogue and then click setting-setting in lower part select when numlock is off then click the OK button. Press the Left Shift, Left Alt, and Numlock again and then click ok. The cursor can then be controlled by moving the mouse device as normal, or by holding down the numbers around '5' on the number pad, and clicking can be performed by pressing '5' on the number pad.

Mac OS X users can do the same thing by using Universal Access in System Preferences. In Mac OS X's Universal Access window, select the Mouse & Trackpad pane and then turn on Mouse Keys. With Mouse Keys turned on, you can navigate around using the number keys on the number pad and mouse-click with the 5 key.

A similar feature can be turned on in Linux (Gnome or KDE) by pressing Left-Shift and Num Lock at the same time.

By positioning the items to be alchemised (in note form) at the left hand end of the fifth inventory row it is possible to repeatedly cast High Alchemy on the items by doing nothing more than pressing the '5' key at the correct intervals, with no mouse movement required.

Coins gained from High Alchemy
All items in RuneScape have a fixed amount of coins that the High Level Alchemy spell yields. Some can turn a profit, but most will provide much less money than if they were sold to another player. A small list of items includes:
 * *** = NOT recommended for high alchemy

Trivia

 * After the high detail update the animations for High Level Alchemy were updated. There was much speculation about whether the new animation was slower than the old animation as it seemed so, but the RuneScape clock shows that they are the same speed.
 * The lowest price of any item on the grand exchange will never drop past 280 coins less than the high alchemy value, and there are a few items at this limit which high level alchemy can be cast on for a profit.
 * Coins cannot be alchemised. If the spell is cast on coins, the message reads: "Coins are already made of gold...", even though players can still alchemy other items made of gold, such as Gold bars or Gold ores. This is likely to prevent players simply gaining exp, but not losing any money (since 1 coin would be alched to gain 1 coin).
 * The animations for High Level Alchemy is different for players wearing staffs than for players wearing other kinds of weapons, or no weapon at all.
 * Players are able to run and high alchemise things without having to stop.

Glitches



 * Another graphical glitch is that if you walk, then high-alch something with a staff, you will move with the staff on the ground, dragging it. This glitch has been stated to have been fixed by Jagex.
