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

Each amulet begins with five charges. While the amulet is equipped, there is a 5% chance that you will create a 4-dose potion rather than a 3-dose potion when brewing potions (but with no extra experience), which consumes one charge. Once all of the amulet's charges are used up, the amulet crumbles to dust. When the amulet crumbles to dust, the player will either continue making potions or stop depending on the choice selected in the Options menu of the amulet. Each amulet lasts for an average of 100 potions made.

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

The amulet of chemistry can also be used to charge the upgraded variant, the Alchemist's amulet, with an additional 10 charges.

Mechanics

The amulet of chemistry provides no benefit when making potions that always output 4 doses, including antidote+, antidote++, anti-venom+, super combat potion, and super antifire. The amulet will not trigger when creating a Guthix Rest tea; the player will always create a 3 dose cup.

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, forgotten brew, extended antifire, extended super antifire, anti-venom, extended 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 taking 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 taking 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 maximising profit from crystal dust).

Profit

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 (184.6 coins).
