Target a creature of your choice that you can see within range, that target must make a Constitution saving throw. If the creature fails the saving throw its limbs will start glowing a deep red.

On the creature's turn it must make a constitution saving throw, taking 1d6 fire damage on failed save for every action or attack, or half as much on a successful one. For every 5 feet moved the creature also takes 1d4 fire damage.
