Underground

Mossglow

Mossglow is an event that naturally occurs underground (below 0ft depth) at night. It has a 1/8 (12.5%) chance to begin at sundown (7:30 PM) and lasts until sunrise (4:30 AM)

During the event, all types of moss and gem tree give off dim light. Although this is cosmetic, it can make exploring easier.

Corrupted Moss

Corrupted moss grows on impure stone and brick like corrupted grasses grow on dirt, and at the same speed. Illdew and Ichorwort only grow in the Cavern layer. Illdew, Ichorwort, and Frostwork glow. Like other moss, corrupted moss can be harvested with a Paint Scraper at a 1/9 (~11%) drop rate.
