Dellore's Protective Barrier

A 10-foot-radius immobile dome of force springs into existence around and above you and remains stationary for the duration. The spell ends if you leave its area.

Nine creatures of Medium size or smaller can fit inside the dome with you. The spell fails if its area includes a larger creature or more than nine creatures. Creatures and objects can move through it freely. Spells and other magical effects can extend through the dome or be cast through it. Arrows, bolts, and other ordinary projectiles launched at targets within the dome are deflected and automatically miss. Ranged spell attacks and magical ammunition are unaffected by this spell.

The dome is mostly transparent, with a blue hue.
