Calamity Ganon can cast any spell of 6th level or lower with a casting time of 1 action or longer without expending magic points or spell slots (DC 23, +15 to hit with spell attacks, casts as a 20th-level spellcaster). It never requires material components, and automatically succeeds on checks to maintain concentration. In addition, it has the following spells prepared:

7th (3/day): breath of malice, forcecage, project image, withering destruction
8th (2/day): control monster, mind blank, power word stun
9th (1/day): power work kill, true polymorph

Calamity Ganon has advantage on all saving throws. Three times per day, if it fails a saving throw, it can choose to succeed instead.

As part of any attack it makes, Calamity Ganon can choose to wield a magical version of any weapon it could otherwise wield. The weapon is momentarily created out of thin air for the attack. This Gargantuan weapon has four times its normal damage dice, and deals an extra 2d12 necrotic or force damage on a hit. A melee weapon has a reach of 3m, or 6m if it has the reach property. A ranged weapon has four times its normal range. These weapons cease to exist if they leave Calamity Ganon's touch.

Calamity Ganon can't be affected or detected by spells of 6th level or lower unless it wishes to be.

Calamity Ganon deals double damage to objects and structures.

The Calamity Ganon's attacks bypass all forms of damage resistance and damage immunity.

Effects that alter reality do not directly affect the calamity, such as a wish spell. The calamity may make a test of Intelligence saving throws equal to the caster's saving throws.

Calamity Ganon uses its Frightful Presence. It then makes five attacks with light melee weapons, or four attacks otherwise. It can forgo any number of attacks to cast an equal number of cantrips.

Melee Weapon Attack: +20 to hit, reach 2m, one target. Hit: 32 (4d12 + 10) piercing damage plus 13 (2d12) necrotic or force damage.

Melee Weapon Attack: +20 to hit, reach 3m, one target. Hit: 24 (4d6 + 10) slashing damage plus 13 (2d12) necrotic or force damage.

Melee Weapon Attack: +10 to hit, reach 6m, one target. Hit: 46 (4d12 + 20) piercing damage plus 13 (2d12) necrotic or force damage.

Each creature of Calamity Ganon's choice that is within 24m of it and aware of it must succeed on a DC 24 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 Calamity Ganon's Frightful Presence for the next 24 hours.

Calamity Ganon 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. Calamity Ganon regains spent legendary actions at the start of its turn.

Calamity Ganon makes one Wisdom (Perception) check.

Calamity Ganon casts Misty Step.

Calamity Ganon makes one attack with its bite or a light melee weapon.

Calamity Ganon uses its Boundless Spellcasting to cast chromatic explosion, Dispel Magic, or warping step as a 6th-level spell. Alternatively, he can cast any one cantrip.
