Ancient White Dragon

The monster can move across and climb icy surfaces without needing to make an ability check. Additionally, Difficult composed of ice or snow doesn't cost it extra movement.

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

The monster makes three Rend attacks.

Melee Attack: +14 to hit. reach 15 ft. Hit: 2d8 + 8 slashing plus 2d6 cold damage.

Constitution Save: DC 22. target: 90-foot cone, creature. Failure: 14d8 cold damage; success: half.

Constitution Save: DC 22. target: 30-foot sphere, creature. Failure: 4d6 cold damage.

The monster casts Fear, requiring no Material components and using Charisma as the spellcasting ability. The monster can't take this action again until the start of its next turn.

Each creature in a 30-foot Cone must succeed on a Wisdom saving throw or drop whatever it is holding and have the Frightened condition for the duration. A Frightened creature takes the Dash action and moves away from you by the safest route on each of its turns unless there is nowhere to move. If the creature ends its turn in a space where it doesn't have line of sight to you, the creature makes a Wisdom saving throw. On a successful save, the spell ends on that creature.

The monster moves up to half its Speed, and it makes one Rend attack.
