Scaly Barrier

3nd-level abjuration

Classes: cleric, druid, ranger, legendary shaman, warlock, wizard

Casting Time: 1 action

Range: 100 feet

Components: V, S, M (a shed snakeskin)

Duration: Concentration, up to 10 minutes

You create an invisible 10-foot by 10-foot barrier that blocks reptilian creatures from crossing it, including reptilian humanoids, reptilian beasts, dragons, and snake-like or lizard-like aberrations, monstrosities, and fiends. Such creatures can sense the barrier when they are within 10 feet, and intelligent reptilian creatures become suspicious and unfriendly when they notice its presence. Non-sentient reptilian creatures refuse to move through the scaly barrier, though if magically controlled they can be compelled to enter it. Reptilian creatures entering the scaly barrier take 6d6 necrotic damage. A successful Constitution saving throw halves the damage. In addition, reptilian creatures with 6 or fewer Hit Dice must succeed on a Wisdom saving throw or be repelled by the scaly barrier after taking damage, unable to enter it for the remainder of the spell’s duration.
