Glowstone Dust

Glowstone Dust is an item that is found in the Blazing Fortress. If the player walks on the left side past the warp pad through a small patch of Pigmen, they will encounter an abundance of Glowstone. This Glowstone will not leave behind a block when broken, but will regenerate in the exact spot it was broken.

Brewing
When a potion is brewed with Glowstone Dust, it will amplify a potion's level by 1.
