The Glowstone is one of the many Consumables found throughout Elden Ring.
The Glowstone is a type of consumable that can be used to illuminate darkened places. Much like the Rainbow Stone, it can be dropped in almost any area to provide illumination without having to resort to using a torch. It shines much brighter in dark places than Rainbow stones - though it lacks the color and the ability to chime different sounds the farther it drops.
