• 3rd Level (3 slots): Counterspell, Slow

Multiattack. Beatrice makes three attacks chosen from her Minya or Crystalline Spike options. She can replace one of those attacks with Door crossing.

Crystalline Spike. Melee Spell Attack: +11 to hit, reach 5 ft., one target. Hit: 14 (2d6 + 7) Force damage. If the target is a creature, it must succeed on a DC 19 Strength saving throw or be pushed up to 10 feet away from Beatrice.

Minya. Ranged Spell Attack: +11 to hit, range 120 ft., one target. Hit: 16 (2d8 + 7) Force damage. If the target is a creature, its speed is reduced by 10 feet until the start of Beatrice’s next turn.

Shamak (Recharge 5–6). Beatrice releases a cloud of absolute darkness in a 30-foot cone. Each creature in that area must make a DC 19 Intelligence saving throw. On a failed save, a creature takes 31 (7d8) Psychic damage and gains the blinded and deafened conditions for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Beatrice casts Prismatic Wall (9th-level spell), creating a shimmering, multicolored plane of light up to 90 feet long, 30 feet high, and 1 inch thick, centered on a point she can see within 60 feet.
