Archbishop Freddrik Sol

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

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

Regeneration. Freddrik regains 10 hit points at the start of his turn. If he takes radiant damage, this trait doesn't function at the start of his next turn. Freddrik only dies if he starts his turn with 0 hit points and doesn't regenerate.

Ventriloquism. Whenever Freddrik speaks, he can choose a point within 60 feet; his voice emanates from that point. 

Spellcasting. Freddrik is a 18th-level spellcaster. Its spellcasting ability is Wisdom (spell save DC 19, +11 to hit with spell attacks). Freddrik has following cleric spells prepared:

Cantrips (at will): toll the dead, spare the dying, thaumaturgy, sacred flame

1st level (4 slots): bane, cure wounds, inflict wounds, guiding bolt, sanctuary

2nd level (3 slots): blindness/deafness, hold person, lesser restoration

Multiattack. Freddrik makes one longsword attack and uses his Raise Reason once.

Ceremonial Longsword. Melee Weapon Attack: +9 to hit, reach 5 ft., 1 target. Hit: 8 (1d8 + 5) slashing damage, or 9 (1d10 + 5) slashing damage if used with two hands, plus 16 (3d10) necrotic damage. If the target is a creature, its hit point maximum is reduced by an amount equal to half of the necrotic damage.

Raze Reason. Freddrik targets one creature he can see within 10 feet of him. The target must succeed on a DC 19 Wisdom saving throw or become frightened of him for 1 minute. While frightened in this way, the target must take the Dash action and move away from Freddrik by the safest available route on each of its turns, unless there is nowhere to move, in which case it needn’t take the Dash action. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Teleport. Freddrik magically teleports, along with any equipment he is wearing and carrying, up to 120 feet to an unoccupied space he can see. 

Twisting Words. Freddrik targets one creature he can see within 60 feet of him. The target must succeed on a DC 19 Charisma saving throw or become charmed by Freddrik for 1 minute. The charmed target can repeat the saving throw if Freddrik deals any damage to it. A creature that succeeds on the saving throw is immune to Freddrik’s Twisting Words for 24 hours.

Freddrik 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. Freddrik regains spent legendary actions at the start of his turn. 

Assault (Costs 2 Actions). Freddrik attacks with his ceremonial longsword or uses his Raze Reason. 

Cast a Spell (Costs 2 Actions). Freddrik casts a spell from his spell list as normal. 

Corrupting Guidance. Freddrik uses Twisting Words. Alternatively, he targets one creature charmed by him that is within 60 feet; that charmed creature must make a DC 19 Charisma saving throw. On a failure, Freddrik decides how the target acts during their next turn. 

Teleport. Freddrik uses his teleport action.
