The powerful adamantine dragons are one of several dragons known as skymetal dragons. The innate magic that flows through these dragons causes them to draw particular metals to their bodies like magnets or, in some cases, naturally grow these skymetals on their bodies.

Adamantine dragons are typically steadfast and loyal. Once they commit to a ce

Swallow Whole (attack) — Large, 3d12+14 bludgeoning, Rupture 35
The monster attempts to swallow a creature of the listed size or smaller that it has grabbed or restrained in its jaws or mouth. If a swallowed creature is of the maximum size listed, the monster can't use Swallow Whole again. If the creature is smaller than the maximum, the monster can usually swallow more creatures; the GM determines the maximum. The monster attempts an Athletics check opposed by the grabbed creature's Reflex DC. If it succeeds, it swallows the creature. The monster's mouth or jaws no longer grab a creature it has swallowed, so the monster is free to use them to Strike or Grab once again. The monster can't attack creatures it has swallowed.
A swallowed creature is Grabbed, is Slowed 1, and has to hold its breath or start suffocating. The swallowed creature takes the listed amount of damage when first swallowed and at the end of each of its turns while it's swallowed. If the victim Escapes this ability's grabbed condition, it exits through the monster's mouth. This frees any other creature grabbed in the monster's mouth or jaws. A swallowed creature can attack the monster that has swallowed it, but only with unarmed attacks or with weapons of light Bulk or less. The swallowing creature is Off-Guard against the attack. If the monster takes piercing or slashing damage equaling or exceeding the listed Rupture value from a single attack or spell, the swallowed creature cuts itself free. A creature that gets free by either Escaping or cutting itself free can immediately breathe and exits the swallowing monster's space.
Effect: Engulf and Swallow Whole
If the monster dies, a swallowed creature can be freed by creatures adjacent to the corpse if they spend a combined total of 3 actions cutting the monster open with a weapon or unarmed attack that deals piercing or slashing damage.

WORKS WELL WITH
SnareLAND / SUBTERRANEANA controller that clusters or roots foes turns the wide cone breath into a near-guaranteed multi-target hit.
SniperLAND / AERIALA ranged attacker can pick off survivors fleeing the dragon's melee reach without contesting its space.
ShadeLAND / SUBTERRANEANAn ambush-oriented ally can slip through the chaos the dragon's tunneling and breath create while it holds the party's full attention.
PUNISHES
✖ clumping✖ reliance on stone cover✖ melee reliance
