Charcoal is a Resource Node found under in the BBQ Spill area. It can be cracked with a Insect Hammer, Black Ox Hammer, Splatburst and Blaster of the Moldy Matriarch. It is surrounded by larger, hot charcoal that will create a lethal sizzle effect, similar to the Sandbox. To survive it without it instantly heating the player up, the player needs a full set of Antlion Armor and a Quesadillantlion, but even with this much sizzle protection, it is still potentially lethal.
Once harvested charcoal take 5 in-game days to respawn.
