Binding Spell Circle

Using the power of the arcane inside you create a magical spell circle attempting to bind a creature, if the spell succeeds four stakes are pushed into the ground securing chains holding the creature down. For a creature of a CR 5 or bellow, the creature needs to make a 1d10 plus spell level saving throw or be trapped unable to make any attacks, cast spells, or make any ability checks and saving throw for 5 turns. For a creature with a CR of 6 and above the caster of this spell must use 1 HP per 1 CR above 5. If any creature wishes to free the trapped creature, it must make a DC 15 saving throw to remove one of the four stakes holding the spell together. If all four stakes are removed the creature will be freed prematurely. This spell takes up your entire turn and can be interrupted by the caster being attacked and is completed if the creature being targeted fails the check on their turn.
