Furnace is an Invention perk that has a chance to consume a gathered resource for double the normal experience. It can be created in tool gizmos.

When activated while fishing, the message Your furnace perk consumes a fish and gives you extra XP. appears. When activated while mining/woodcutting, the message Your furnace perk consumes some ore/wood and gives you extra XP. appears. When activated while gathering crystal fragments, fishing crystal urchins, mining gem stones, mining crablets, or chopping bamboos, the message Your furnace perk consumes some of what you gather and gives you extra XP. appears.

Furnace perk doesn't work on skilling plots that won't produce resource to consume, e.g. crystal tree and choking Ivy. However, the perk does work with the shark outfit, even when it is set to consume caught fish.

Resources that are not affected by furnace perk:

The extra experience received from furnace will stack with bonus experience. The perk effectively grants 5% extra experience per rank. Items consumed by the perk also grant double equipment experience.

Items consumed by the perk do not count towards a Daily challenge.
