Amulet of chemistry detail.png

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.

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 potion, 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 maximising 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 (200.4).
