Tasha's Caustic Brew - Cold Transmuted

Tasha's Glacial Freeze

A stream of cold 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 thick frost for the spell’s duration or until a creature uses its action to scrape the frost off itself or another creature.

A creature covered in frost suffers no damage but has its movement speed halved, and cannot take reactions.

Regardless of the creature's abilities or magic items, it can't make more than half of it's normal melee or ranged attacks during its turn (rounded up).

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
