Legendary Resistance (10/Day). If Zeus fails a saving throw, it can choose to succeed instead.

Multiattack. Zeus can use his Frightful Presence. He then makes three attacks with his lightning bolts.

Frightful Presence. Each creature of Zeus's choice that is within 120 feet of him and aware of it must succeed on a DC 26 Wisdom saving throw or become frightened for 1 minute. 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 Zeus's Frightful Presence for the next 24 hours.

Lightning Bolt. Zeus throws a single bolt of lightning. Ranged Weapon Attack: +16 to hit, range 2000 ft., one target. Hit: 70 (12d12 + 12) lightning damage plus 11 (2d10) piercing damage.

Lightning Spread (Recharge 5–6). Zeus throws lightning in a 180-­foot cone. Each creature in that line must make a DC 26 Dexterity saving throw, taking 176 (32d10) lightning damage on a failed save, or half as much damage on a successful one.

Zeus can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. Zeus regains spent legendary actions at the start of its turn.

Detect. Zeus makes a Wisdom (Perception) check.

Bolt. Zeus makes a Lightning Bolt attack.

Lightning Spread (Costs 3 Actions). Zeus immediately recharges his Lightning Spread, then uses it.
