The ring of fire that appears when using the Inferno Potion.
The ring of fire at night.
The Inferno Potion is a buff potion that buffs the player with Inferno, which casts a ring of fire that inflicts low damage and the On Fire! Debuff on some enemies on contact as well as giving off light. Critters and other passive NPCs are spared. It can be crafted or found in Shadow Chests. The buff lasts for 4 minutes.
- Crafting this potion requires a Hotline Fishing Hook, as its two fish ingredients can only be caught in lava.
- Enemies that are immune to On Fire! are also immune to damage from the Inferno.
- While the ring deals minimal damage to most Hardmode enemies, this potion is extremely useful when fighting Duke Fishron because his Detonating Bubbles will be destroyed before they can damage the player. It is also useful in the Wall Of Flesh for keeping the hungry at bay, or for fighting Plantera, to kill spores and keep the hooks away from you.
- In the 3DS version, there is an exploit involving this item, where pausing with the buff active will keep the hitboxes active. This is immensely helpful against mobile Hardmode bosses, such as Duke Fishron.
