Canoness Ydris, the Lacquered Saint

Legendary Resistance (3/Day)

Empty Frame Aura
Enemies that start their turn within 10 ft must succeed on a DC 18 Wisdom saving throw or have disadvantage on their first attack roll or ability check that turn. On a success, the creature is immune to this aura for 24 hours.

Triptych Masks
At the start of each of her turns, Ydris chooses one mask until the start of her next turn:

• Mask of Vigil: +2 AC and advantage on Dexterity saving throws.
• Mask of Mercy: Healing Ydris deals or receives increases by 5, and allies within 10 ft have advantage on death saving throws.
• Mask of Rest: When a creature within 60 ft fails a saving throw against Ydris’s spells, it also takes 1d6 psychic damage.

Description:
Ydris targets a point within 120 ft. Each creature in a 20-foot-radius sphere must make a DC 18 Dexterity saving throw. On a failure, a creature takes 8d8 radiant damage and is slashed by glass for 1 minute: its speed is reduced by 10 feet and it takes 1d8 slashing damage at the start of each of its turns. A creature can use its action to clear the glass and end the effect. On a success, it takes half damage and suffers no ongoing effect.

MYTHIC PHASE 2:

At 0 hit points, Ydris sheds her plates and a Saint-Golem Avatar appears with 120 hit points and shares initiative. While it lives, Ydris revives herself automatically to 15 HP and cannot be damaged until the Saint-Golem Avatar is defeated. She also regains one legendary resistance and Shatterglass Nova recharges at the start of her turn.
