Armor of Thorns

You infect a creature’s senses, making its armor feel as though it has become lined with inward-facing thorns.

Choose one creature you can see within range that is wearing armor. The target must make an Intelligence saving throw.

On a failed save, the target must spend its next action tearing off its armor. While affected by this spell, armor removed in this way is doffed as an action regardless of its normal doffing time.

On a successful save, the target sees through the illusion enough to keep functioning, but still suffers phantom pain. It acts normally and takes 2d6 psychic damage.

This spell has no effect on a creature that is not wearing armor or whose Armor Class comes only from natural armor.
