Trigger A creature at least 10 feet away from the dragon targets them with an attack
Requirements The dragon is on the ground and there is at least one unoccupied square between themself and the attacker
Effect The dragon conjures a thin slab of stone in an unoccupied square between themself and the attacker. The dragon gains standard Cover against the triggering attack. The stone falls on the first person other than the dragon who enters that square, dealing 4d6 bludgeoning damage with a DC 22 reflex save. Otherwise, it crumbles harmlessly after 1 round.
Draconic Frenzy
The dragon makes two claw Strikes and one tail Strike in any order.
Draconic MomentumThe dragon recharges their Ornamental Breath whenever they score a critical hit with a Strike.
Ornamental Breath
(primal)The dragon exhales a torrent of shattered rocks and minerals in a 30-foot cone dealing 7d6 piercing damage (DC 25 reflex save). A creature who fails the save is weighed down by the stones, becoming Clumsy 1 (Clumsy 2 on a critical failure).
Crystal dragons consider themselves among the more beautiful dragon species and expect others to recognize this. They see little need to accessorize their crystalline hides but might spend hours each day tending to their appearance. They clean themselves frequently, and each scale must be properly faceted and free of imperfections. A crystal dragon may retreat into its lair if its hide gets damaged, manually removing the damaged scales (a painful process!) and then waiting for the replacements to grow in.
Crystal dragons are also proud of their lairs, which typically contain hoards of gems and crystals. An individual dragon's creative nature shows through in their decor. So do their organizational skills—they can't tolerate a mess. Their habit of constantly updating and rearranging their spaces means visitors might see a fair bit of disarray, however, depending on their timing.

A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
DragonDragons are reptilian creatures, often winged or with the power of flight. Most can exhale magical energy and are immune to sleep and paralysis.
