Wiki is currently undergoing a revamp! If you see some pages that are more polished, it means they've been revamped.
Some effects from spore can have a potion form. Mycelium Infection, Marker, and Corrosion are the only effects that can be brewed. All potions can be used to brew splash potions (via gunpowder,) lingering potions (via dragon's breath,) and tipped arrows (crafted with eight arrows around a lingering potion of the desired effect.)
