The dragon can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if it ends its turn inside an object.

Legendary Resistance (3/ Day)

If the dragon fails a saving throw, it can choose to succeed instead.

Breath Weapon

Recharge 5–6

The dragon uses one of the following breath weapons:
Radiant Breath. The dragon exhales radiant energy in a 60-foot cone. Each creature in that area must make a DC 19 Dexterity saving throw, taking 55 (10d10) radiant damage on a failed save, or half as much damage on a successful one.
Flaring Breath. The dragon emits a flash of dazzling light from its maw in a 60-foot cone. Each creature in that area must make a DC 19 Constitution saving throw or be blinded.

A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the dragon's Frightful Presence for the next 24 hours.
