The Pitch can (blue) is an item used in The Firemaker's Curse. It can be used to create fires without needing to use logs, granting 2 experience points for each fire made. The fires cannot be walked over or stood on, and you can stamp out the red fires whenever you want by clicking on it to stamp it out. Using blue powder on a pitch can will make it a blue pitch can.
A player lighting a fire using a pitch can.
During the quest, you can receive another one from Flint.
If Flint is killed by Twig or after the quest is completed, the pitch can will simply appear on the floor for the player to collect.
