Torture

Tapping into dark, forbidden magic you target an creature within 15 feet of you with a size of larger or smaller to torture via magical means. The target must make a DC 15 Constitution saving throw or become engulfed in cruel magic taking a form of your choice. On a failure the creature is restrained and unable to do anything but speak, taking 1d10 + your spell casting modifier force damage every turn. At the end of each of it's turns, the target can make another Constitution saving throw, with the DC increasing by 1 for each turn the target has taken damage. Once the DC for this spell reaches 20, the target stops making saving throws and becomes trapped until either released from the spell by you, the spell is ended by a dispel magic spell or similar effect, or you drop below 0 HP.

A creature that drops to 0 HP due to the effects of this spell or is unconscious when this spell is cast is immediately stabilized and remains conscious, but continues to feel pain and take damage. Additionally, the target is also unable to sleep while actively taking damage from this spell. This spell has no effect on creatures that cannot feel pain such as certain constructs and undead.
