The alchemist's amulet is an item purchased from the Mixology Rewards shop with 6,900 Mox resin, 5,650 Aga resin, and 7,400 Lye resin, which are earned from participating in the Mastering Mixology minigame. While the amulet is equipped, there is a 15% chance the player will create a potion with an extra dose when brewing potions (but with no extra experience), which consumes one charge. This effect works when adding secondaries to potions with fewer than 4 doses, such as anti-venom and stamina potions.

When first purchased, the amulet is pre-charged with 50 uses. Additional charges can be added by using amulets of chemistry on it, each giving 10 charges, up to a maximum of 5,000. On average, each Amulet of chemistry added will last for ~67 potions made, giving a fully charged Alchemist's amulet ~33,333 potions made, of which 5,000 will have an extra dose.

When the player uncharges the amulet, it returns amulets of chemistry in noted form, equal to the number of charges divided by 10 (rounded down).

Unlike the amulet of chemistry, there is no option on the amulet to stop the player from making potions once it has depleted all charges.

If killed by a player while wearing this amulet unprotected, it will appear at your gravestone with 0 charges.

Mechanics

The alchemist's amulet 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 Guthix rest tea; the player will always create a 3 dose cup.

When used with potion recipes 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 stamina potion, extreme energy potion, forgotten brew, extended antifire, extended super antifire, anti-venom, extended anti-venom+, and all of the divine potions. Because the amulet effect always adds one dose, making any of these potions with fewer doses increases average bonus yield per dose but takes significantly more time than processing 4-dose potions - a tradeoff that may be valuable for ironmen or to maximise profit of crystal dust.

3-dose 2-dose 1-dose
Bonus yield per dose 5% 7.5% 15%
Extra time taken 33% 100% 300%

Despite not being a potion, the amulet also affects Haemostatic dressing, creating 4 'doses' instead of 3.

Profit

Since each amulet of chemistry adds ten charges, whereas the amulet of chemistry itself only has 5 charges, the cost per charge of using the Alchemist's amulet is effectively half that of the amulet of chemistry. 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 1/10th of the requisite amulet of chemistry's worth (176 coins).
