Lava


 * "Lump of lava that dropped off a grock's body."

Lava are common ores that are dropped by Magmagrocks and Vulcangrocks. These items are cooled magma in a shape much like the shards. These items are really common when grinding those specific grocks, but at least Dillon can get money off of it.

Trivia

 * Previously being magma, the lava is in a solid state at 650°C, hot enough to burn the fibers on Dillon's packs where he keeps all of his items.
