Enslavement

When a creature is incapacitated, stunned, unconscious or willing (unable to move or make the casting difficult) the caster draws a symbol of significant importance (like an evil god's or family crest) in ink, then surrounds the symbol with the blood of the target with their finger. once the spell takes affect, the target must do as the caster says or takes 1d6 psychic damage, if the creature is reduced to 0 hit points then it becomes unconscious and does not die.
