Tasha's Caustic Brew - Fire Transmuted

Tasha's Potential Immolator

A stream of flammable liquid emanates from you in a line 30 feet long and 5 feet wide in a direction you choose. Each creature in the line must succeed on a Dexterity saving throw or be covered in the liquid for the spell’s duration or until a creature uses its action to scrape or wash the liquid off itself or another creature.

If a creature covered in the liquid takes fire damage they receive 2d10 fire damage at the start of each of its turns for the duration. Once a creature is on fire it takes 2 actions (this can be two consecutive actions from one creature, or two creatures working together for one turn) to remove the liquid.

Usage of this spell consumes one sorcery point

At Higher Levels. A side-effect of spell transmutation is that spells cannot be cast at higher levels
