Wall of Denial

You summon a 10 foot wide, 10 foot tall and 1 inch thick wall
of magical force to impede foes passage that extends from a
point you choose within range. Before you cast the spell,
choose who may pass through it. Those who are chosen may
walk through unimpeded. Anyone else must make a Strength
Saving Throw. If they succeed, they pass through. If they fail,
they are forced to stop and cannot move through the wall for
the rest of their turn. The wall has 5 HP and 10 AC. If it's HP
reaches 0, the wall dissipates.
The wall’s HP goes up by 5 at level 5(10 HP), level 11(15
HP) and level 17(20 HP).
