Tilbys cage

An imperceptible barrier of magical force is protected and surrounds a small or medium creature caging them. 

Until the end of your next turn,  the target creature is held within a magical barrier. They can not move, or attack with a melee weapon a creature outside the barrier. Spells can be cast though it but take a -5 penalty to attack and damage roles. They can attempt to break out the barrier as an action, and have to succeed on a DC 16 strength check.
