Archmother Mildred Matilde

Ritual Magic (1/Day). While within 30 feet of a number of allies equal to twice the spell level, Matilde can cast one of the following spells, taking a casting time of one hour, and using Wisdom as the spellcasting ability (spell save DC 22): Commune, Dispel Evil and Good, Hallow, Heroes' Feast, Planar Binding, or Plane Shift. Matilde must finish a Long Rest before using this trait to cast that spell again.

Orb of Eclipses (1/Day). While wielding the orb of eclipses, Matilde can cast Teleport or Scrying.

Legendary Resistance (3/Day, or 4/Day in Lair). If Matilde fails a saving throw, she can choose to succeed instead.

Magic Resistance. While wearing the robe of the archmagi, Matilde has Advantage on saving throws against spells and other magical effects.

Celestial Escape. When Matilde drops to 0 Hit Points, she dies only if she is within 30 feet of her anathema. Otherwise, she drops to 1 Hit Point and teleports to a harmless demiplane, and can’t return to the plane she left for 2d6 days. When Matilde teleports away, each creature of her choice within 60 feet of the space it left gains the Bless spell effect. Until the spell effect ends, a creature has Advantage on ability checks and saving throws, and Matilde knows their location anywhere in the multiverse.

Multiattack. Matilde makes two Brilliant Hand attacks and uses Beacon of Hope.

Brilliant Hand. Melee or Ranged Attack Roll: +14, reach 5 ft. or range 60 ft. Hit: 17 (3d6 + 7) Radiant damage. Matilde may instead heal the target with the amount rolled, as well as granting the creature the Bless spell effect until the end of the target's next turn.

Beacon of Hope. Charisma Saving Throw: DC 22, all creatures of Matilde's choice in a 30-foot Emanation. Failure: 32 (5d12) Radiant damage and the Blinded condition until the end of the target's next turn. Success: Half damage. Targets that have the Bless spell effect gain resistance to one damage type Matilde chooses, as well as advantage on all Saving Throws until Matilde's next turn.

Spellcasting. Matilde casts one of the following spells, requiring no Material components and using Wisdom as the spellcasting ability (spell save DC 22):

At Will: Detect Evil and Good, Detect Thoughts, Dimension Door, Dispel Magic, Gentle Repose, Zone of Truth
2/Day Each: Death Ward, Flame Strike (level 6 version), Fount of Moonlight, Heal, Greater Restoration, Word of Recall
1/Day Each: Blade Barrier, Leomund's Secret Chest, Vitriolic Sphere

Benign Transposition. One creature that Matilde can see within 60 feet with the Bless spell effect teleports to an unoccupied space she can see within 60 feet. Alternatively, she can choose a space within range that is occupied by another creature with the Bless spell effect, they both teleport, swapping places.

Spellbreaker. When Matilde heals a creature, she may end a spell effect or curse on that creature. 

Legendary Action Uses: 3 (4 in Lair). Immediately after another creature’s turn, Matilde can expend a use to take one of the following actions. She regains all expended uses at the start of each of her turns.

Brillant Swipe. Matilde uses her Brilliant Hand action.

Malicious Magic. Matilde casts a spell from her Spellcasting. Matilde can’t take this action again until the start of its next turn.
