In-game description

Accelerant is a tool that aids in lighting fires. It comes in a container labeled Quickflame and stacks in the inventory.


One entire bottle of accelerant or 0.3 liters of Kerosene when starting a fire to increase the probability of the fire igniting by 40%.

While accelerant is non-renewable, lantern fuel can be acquired from cooking fish. Accelerant is lighter than 0.30 L of kerosene (0.24 kg plus the 0.10 kg container). In other words, it is best to use kerosene to start fires and keep accelerant on the player for emergencies, such as when starting a fire to hold wolves at bay, or when in imminent danger of freezing to death.
