Legendary Resistance (3/day). If the dragon fails a saving throw, it can choose to succeed instead.
Spell Reflection. Any time the glass wyrm is targeted by a magic missile spell, a line spell, or a spell that requires a ranged attack roll, roll a d6. On a 1 to 5, the dragon is unaffected. On a 6, the dragon is unaffected, and the effect is reflected back at the caster as though it originated from the dragon, turning the caster into the target.
Actions
Multiattack. The glass wyrm uses its blinding reflection ability, and makes one bite attack and two claw attacks.
Bite. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 15 (2d8 + 6) piercing damage.
Claw. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 17 (2d10 + 6) slashing damage.
Blinding Reflection. The glass wyrm reflects available light in a burst of radiance out to a 30-foot radius. Creatures that can see the glass wyrm in the area must succeed on a DC 17 Dexterity saving throw or be blinded for 1 minute. A blinded creature can attempt a DC 17 Constitution saving throw at the end of each of its turns, ending the blinded condition on a success.
The glass wyrm can’t use this ability if it does not begin its turn within the dim light or bright light radius of a light source.
Glass Shards (Recharge 5–6). The glass wyrm breaths a 40-foot cone of glass razor-like glass shards. Creatures in the area must succeed on a DC 17 Dexterity saving throw, taking 54 (12d8) piercing damage on a failed saving throw, or half as much damage on a successful one.
