Has a 0.1% chance per rank of burning all logs of the same type from the inventory.

Gizmo type Tool
Maximum rank 5

Pyromaniac is an Invention perk that has a 0.1% chance per rank to burn all of the logs of the same type in your inventory at once when adding logs to a bonfire. It can be created in tool gizmos.

When the perk triggers, it prompts the message: Your pyromaniac perk allows you to burn all your logs at once!

Pyromaniac does not consume any logs being held by a Beast of Burden (BoB) familiar, but using a BoB to keep the inventory topped up can reduce the intensity of the training while increasing the effectiveness of this perk.

This perk does not work with protean logs, and burning protean logs with tradeable logs in the inventory will also not work.

Suggested gizmos

The combination of Pyromaniac 5 and Rapid 2 is very rare, but offers a greater total increase in experience rate than Pyromaniac 5. It is suggested to pair one of these gizmos with a second gizmo containing Tinker 3 in an augmented crystal tinderbox.
