Brunela, the scribe

Brunela, the middle sister,sells scrolls, all of them damaging or noxious in some way or another. Her stock includes the following scrolls:

Cantrips - 50 to 100 gp: chill touch, vicious mockery

1st Level - 50 to 100 gp: bane, faerie fire, hideous laughter

2nd Level - 101 to 500 gp: enthrall, ray of enfeeblement

3rd Level - 101 to 500 gp: fear, vampiric touch

4th Level - 501 to 5,000 gp: blight, phantasmal killer

She also sells scrolls of her signature spell that she created to help Arabela with her potions, but she hopes the adventuring party finds a use for it that makes someone particularly miserable:

Cauldron Bubble: 2nd-level transmutation Casting Time: 1 action Range: 30 feet Components: V S M (A wooden spoon) Duration: Concentration, Up to 1 hour Classes: Bard, Druid, Warlock, Wizard

You make a 20-foot cube of any liquid you can see instantly boil. If a creature is submerged in the liquid, it takes 2d6 fire damage at the start of its turn as long as it’s submerged. If the creature leaves the boiling liquid, it takes 2d6 fire damage for an additional turn as the liquid on its skin or clothing cools down.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the size of the cube increases by 10 feet for each slot level above 2nd.
