Controlled Heat Potion

The Controlled Heat Potion is a potion that can be made with Herblore. While active, it causes Firemaking bonfires to automatically be relit after they burn out at the cost of one potion charge instead of logs.

This page is up to date (v1.2.2).

Notes

• The potion will only restart an existing bonfire, it won't start a bonfire if none is already going.
• The bonfire will have the duration and XP bonus of whatever log the player is burning at the time the previous bonfire's duration runs out.
