FAQ
How do I get Glow Lichen?
Break it with shears to collect it as a drop; breaking it with any other tool destroys it without a drop. It also generates naturally in caves on stone, deepslate, and similar blocks near air or water.
How much light does Glow Lichen produce?
Each glow lichen block emits a light level of 7, enough to provide modest illumination in caves without being as bright as a torch.
Can Glow Lichen spread?
Yes, applying bone meal to a glow lichen block causes it to spread onto adjacent valid surfaces, similar to how vines and other lichen-like blocks propagate.
Does Glow Lichen affect water or lava flow?
It can block or redirect water flow since it is a solid-ish obstruction to fluids, but it burns away if exposed to lava or fire since it is flammable.
