Amulet of chemistry detail.png

An amulet of chemistry is a jade amulet enchanted via the Lvl-2 Enchant spell.

When equipped, there is a 5% chance to give you an extra dose when brewing potions. The amulet will provide five charges before breaking. As of an update on 27 July 2017, players can right-click Options on the amulet to toggle whether they would like to stop making potions when the amulet breaks.

Similar to a ring of recoil, amulet of chemistry charges are stored per player, not per amulet. Thus if the player sells or casts High Level Alchemy on an amulet with 1 charge remaining, the next amulet the player equips will still have only 1 charge. The player can right-click to "break" an amulet of chemistry, destroying it and restoring the next amulet of chemistry the player equips to 5 charges.

Mechanics[edit | edit source]

The amulet of chemistry provides no benefit when making potions that always output 4 doses, including Antidote+, Antidote++, Anti-venom+, Super Combat, and Super Antifire.

When used with potions that create a variable number of doses, the amulet will only trigger if the input potion is less than 4 doses. These potions include Stamina potion, Extended antifire, Extended super antifire, Anti-venom, and all of the Divine potions. When used with 3 dose potions, the amulet will extend 60 doses into 61 doses, providing an average 1.66% increase in yield and take 33% longer to make. For 2 dose potions, the amulet will extend 40 doses into 41 doses, providing an average 2.5% increase in yield and take 100% longer to make. For single dose potions, the amulet will extend 20 doses into 21 doses, providing an average 5% increase in yield and take 300% longer to make. This takes much more time, but can be useful extending supplies when acquiring ingredients takes a significant amount of time (such as on Ironmen accounts, or maximizing profit from crystal dust).

Profit[edit | edit source]

When using the amulet for solely profit, it should only be used when a single dose of the potion you make has a value of more than 1/5th of the amulet's worth (201.4).
