Poisonous Flesh

2nd-level transmutation

Casting Time: 1 action
Range: Self
Components: V, S, M (a sprig of milkweed)
Duration: Concentration, up to 1 hour

You make your flesh and blood poisonous, deterring creatures that might want to devour you. For the duration, any creature that hits you with a bite attack must make a Constitution saving throw. On a failed save, it takes 2d8 poison damage and is poisoned for 1 minute. On a successful save, the creature takes half as much damage and is not poisoned. Creatures with an Intelligence of 5 or lower will not willingly bite you again, seeking other prey instead. If such a creature is unable to disengage from combat with you, it will use other attack actions to deal damage if possible, but will continue to use its bite attack if it has no other option.

If you are swallowed by a creature, immediately after you take whatever damage is dealt by the creature’s digestion, the creature takes 4d8 poison damage and is poisoned for 1 hour. A successful Constitution saving throw negates the poisoned condition. On its next turn, the creature uses an action to spit you out.
