Ice Walk. The dragon can move across and climb icy surfaces without needing to make an ability check. Additionally, Difficult Terrain composed of ice or snow doesn’t cost it extra movement.
Legendary Resistance (3/Day, or 4/Day in Lair). If the dragon fails a saving throw, it can choose to succeed instead.
Multiattack. The dragon makes three Rend attacks.
Rend. Melee Attack Roll: +12, reach 10 ft. Hit: 15 (2d6 + 8) Slashing damage plus 4 (1d8) Cold damage.

Cold Breath (Recharge 5–6). Constitution Saving Throw: DC 19, each creature in a 60-foot Cone. Failure: 67 (15d8) Cold damage. Success: Half damage.
Legendary Action Uses: 3 (4 in Lair). Immediately after another creature’s turn, the dragon can expend a use to take one of the following actions. The dragon regains all expended uses at the start of each of its turns.
Freezing Burst. Constitution Saving Throw: DC 14, each creature in a 30-foot-radius Sphere centered on a point the dragon can see within 120 feet. Failure: 7 (2d6) Cold damage, and the target’s Speed is 0 until the end of the target’s next turn. Failure or Success: The dragon can’t take this action again until the start of its next turn.
Frightful Presence. The dragon casts Fear, requiring no Material components and using Charisma as the spellcasting ability (spell save DC 14). The dragon can’t take this action again until the start of its next turn.
Pounce. The dragon moves up to half its Speed, and it makes one Rend attack.
Description
Villain Actions
(One per round, at end of another creature’s turn. Each is one-and-done during the fight, in order.)
Round 1: Frost Nova
Arauthator slams his claws into the ice, triggering a massive shockwave of cold.
- All creatures within 30 ft. must make a DC 18 Con save or take 4d8 cold and be restrained in ice until the end of their next turn (save ends).
- The area becomes difficult terrain for 1 round.
Round 2: Glacial Retaliation
- Arauthator shatters a portion of the lair—ice spikes erupt from the ground.
- Up to three creatures of his choice within 60 feet must make a DC 18 Dex save or take 6d6 piercing damage and 2d6 cold damage, and be knocked prone.
Round 3: Blizzard Roar
- Arauthator unleashes a roar that calls a minor blizzard within the lair.
- The area is heavily obscured for 1 round (except for him), and all creatures must make a DC 16 Wis save or become frightened until the end of their next turn.
- Additionally, at initiative 20 on the following round, flying creatures not immune to cold are forced to land.
