Axel's Construct Prison

      -You construct a cube shaped prison 50ft by 50ft by 50ft and each wall is 5ft wide.

      -Once you have spent a minute casting this spell, the creature inside can only escape by destroying at least 1 of the prison walls.

      -The prison walls have an AC of 25, and each wall has 350 hp.

      -If you manage to break one of the walls the spell ends and the prison crumbles.

      -If the spell ends due to breaking a wall everyone within 100ft must make a Constitution saving throw of 23 or take 4d10 force damage, or half as much on a success, and be knocked prone.

      - If you hold concentration on this spell for 1 minute, it becomes permanented unless the prison is destroyed.

      -Once the prison becomes permanented the creature inside starts to suffocate unless the creature does not need oxygen to live.

      -If the creature inside the prison is a construct of size huge or smaller it is deactivated. All abilities stop working, and the target cannot make any action while inside the prison.
