Amulet of chemistry

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 disappearing.

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.
