Extra Reaction The dragon gains 2 reactions at the start of each of their turns.

Frightful Presence (aura, emotion, fear, mental) 90 feet, DC 37

Scintillating Aura (aura, evocation, incapacitation, primal, visual) 30 feet. A swirling vortex of reflected color and light shimmers around the crystal dragon. Creatures in this aura’s emanation are dazzled. Each creature that ends its turn in the emanation must succeed at a DC 34 Will saving throw or be stunned 1 (or stunned 3 on a critical failure). Once a creature succeeds at this save, it is temporarily immune to the stunning effect for 1 minute. The crystal dragon can turn this aura on or off using a single action, which has the concentrate trait, and it can choose not to affect allies.

Reflect Spell [reaction] Trigger The crystal dragon is targeted by a ranged spell attack roll; Effect The crystal dragon adjusts a wing to try to reflect the spell and gains a +4 circumstance bonus to AC against the triggering attack. If the attack misses, the spell is reflected back at the caster, who must roll a second ranged spell attack roll against their own AC to determine if the spell hits them instead.

Twisting Tail [reaction] As young crystal dragon.
