Ecology
Crystalline Devil is a creature of the Lower Planes, present in the mortal world via summoning, banishment-failure, or a planar breach. It is most often found in ruins regions. It is medium-sized, which shapes how it hunts, hides, or fights.
Behaviour
Crystalline Devil is cruel and patient, willing to take centuries to repay an insult. Its Lawful Evil alignment shapes how it engages with the world — predictable in tendency, even when unpredictable in detail. It is intelligent enough to plan, scheme, or remember. Spellcasting expands its repertoire well beyond what its physical stat block alone suggests.
Origin
Crystalline Devil is introduced in Kobold Press's Tome of Beasts 1 (2016). Fiends originate in the Lower Planes — the Nine Hells, the Abyss, or further hells beyond — bound to whatever cosmic hierarchy that plane enforces. Within a campaign, its existence anchors a region with the kind of weight only an old, named species carries.
