The Alchemy Coin is a Relic that is lightly tossed and moves along the ground turning small enemies such as Ratsploders and Blorbs into gold. The coin bounces off of armored enemies, and will bounce back when struck with the Shovel Blade. The Alchemy Coin can be purchased from Chester in Plague Knight's stage for 3000 gold or in the village for 3500 gold if it was not picked up before completion of the level. The Alchemy Coin is the subject of the Reflected Riches feat, which is earned by bouncing the same Alchemy Coin 5 times in a row.
- Interestingly, in the Plague of Shadows expansion, Plague Knight will consider the Alchemy Coin a "worthless relic" upon finding it, even though it is an artifact related to Alchemy.
- However, this could be a reference to famous concept of creating gold through Alchemy, which is often considered the "fool's gold" as it is not true gold.
