A 10-foot-radius immobile dome of force springs into existence around and above a point you see within range and remains stationary for the duration. Nine creatures of Medium size or smaller can fit inside the dome. Creatures can enter or exit the dome without disrupting the spell. Any nonmagical projectile that encounters the surface of the dome is automatically deflected. A magical projectile has a chance to hit, if the attack roll to hit a creature or object within the dome also exceeds your spell save DC.

If the dome is targeted by a ranged spell cast at a higher level than the level this spell is cast at, it penetrates the dome.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the radius increases by 5 feet. If you cast this spell using a 6th level spell slot or higher, no projectile, magical or mundane can pierce the dome, and ranged spell attacks are made at disadvantage. If you cast this spell using a 9th level spell slot, no spell effect can penetrate the dome.
