Innate Spellcasting. Ozymandias’s innate spellcasting ability is Charisma (spell save DC 21). He can innately cast the following spells, requiring no material components:

At will: alter self, bestow curse, major image, modify memory, nondetection, sending, suggestion

3/day each: greater invisibility (self only)

1/day each: feeblemind

Legendary Resistance (3/Day). If Ozymandias fails a saving throw, he can choose to succeed instead.

Magic Resistance. Ozymandias has advantage on saving throws against spells and other magical effects.

Magic Weapons. Ozymandias’s weapon attacks are magical.

Blade Armor. Ozymandias’ gains 1 AC for each of his swords that is active and within 5 feet of him.

Regeneration. Ozymandias regains 60 hit points at the start of his turn. If he takes cold, lightning, or psychic damage, this trait doesn’t function at the start of his next turn. Ozymandias dies only if he starts his turn with 0 hit points and doesn’t regenerate.

Sword Reliance. Each time Ozymandias loses 60 health, one of his swords drops and he loses any abilities associated with it. When this happens, one player character within 5 feet of a sword can make a DC 18 Perception check. If they succeed, they can use their reaction to strike down one specific sword within their attack range. Only one player may do this per 60 health. If no player can make this roll, the GM selects which sword is struck down.

Desolate Mind (Mythic Trait; Recharges after a Short or Long Rest). When Ozymandias is reduced to 0 hit points, he doesn’t die or fall unconscious. Instead, Ozymandias opens a portal to his lair: his home dimension. He goes through the portal, restoring all his HP and removing any status effects. If the party follows, they will end up 60 feet away from him. See Lair description below. If he finishes a short or long rest, he regains the ability. Ozymandias dies when killed in his home dimension.
