Spellcasting. Morrighan is a 5th-level spellcaster. Her spellcasting ability is Charisma (spell save DC 13, +5 to hit with spell attacks). She knows the following spells:
3rd level (2 slots): vampiric touch
Dagger. Melee or Ranged Weapon Attack: +4 to hit, reach 5 ft. or range 20/60 ft., one target. Hit: 4 (1d4 + 2) piercing damage.
Defiant Counterspell. When a creature attacks Morrighan with a spell, she can use her reaction to cause that attack roll to be made with disadvantage. If a critical failure appears on either die, the spell backfires and is triggered upon the caster instead. Rehcharge - 6.

Mad, corrupt, and thoroughly depraved, Morrighan
Conway believes that she can attain powers beyond
reckoning by obtaining control of the essence of the
Krampus. She has spent a lifetime mapping the fiend’s
predations, and can predict where it will appear next.
Her time in service to dark powers has ruined her
once-beautiful features and left her body twisted and
gnarled. She has a cackling laugh, a ghastly smile, and
blood-red eyes that constantly roll around, and even
back into their sockets.
Lair and Lair Actions
Emboldened Recovery. If Morrighan is within the Hirnschule Asylum ritual area, she can use an action to heal 2d6 HP and regain one expended casting of a level 2 or lower spell.
