Cavern Crawler. The irradiated Glyphid exploder can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check. Additionally, moving through difficult terrain doesn’t cost it extra movement.

Death Burst. When the irradiated Glyphid exploder dies, it creates a glowing pool of energy in a 5-foot radius centered on its body. Each creature standing in the glowing pool when it appears or which enters the glowing pool must make a DC 10 Constitution saving throw, taking 7 (2d6) radiant damage on a failed save, or half as much damage on a successful one. The glowing pool lasts for one round before dissipating.

Illumination. The irradiated Glyphid exploder sheds dim light in 5-foot radius.

Actions

Explode. The irradiated Glyphid exploder begins to convulse and ends its turn. At the start of its next turn, it explodes as if by its death burst feature. Any remaining hit points it has are added to the damage of the death burst.
