Ecology

Bone Colossus is a creature that has crossed the threshold of death; its continued presence is itself a violation of natural law. It is most often found in underground regions. It is gargantuan-sized, which shapes how it hunts, hides, or fights.

Behaviour

Bone Colossus is haunted by what it was in life; its goals echo old grievances or the will of the necromancer who raised it. Its Chaotic 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.

Origin

Bone Colossus is introduced in Kobold Press's Tome of Beasts 2 (2020). Undead are the wounds the Negative Plane leaves on the mortal world — every undead has a death story behind it. Within a campaign, its existence anchors a region with the kind of weight only an old, named species carries.
