A powerful, glimmering barrier of magical force appears within a 15-foot radius around you and remains centered on you for the duration.

Nothing can physically pass through the barrier from the outside, however the caster can choose up to 10 creatures it can see to be excluded from this effect. Inanimate objects and the environment around you are also excluded from this effect as you choose. The barrier is immune to all damage and can't be dispelled by dispel magic. Any spell of 8th level or lower cast from outside the barrier can't affect creatures or objects within it, even if the spell is cast using a higher level spell slot. Such a spell can target creatures and objects within the barrier, but the spell has no effect on them. Similarly, the area within the barrier is excluded from the areas affected by such spells. 

A creature outside the barrier can't enter or exit it by nonmagical means. If the creature tries to use teleportation or interplanar travel to pass through the barrier, it must first make a Charisma saving throw. On a success, the creature can use that magic to enter or exit the barrier. On a failure, the creature can't pass the barrier and wastes the use of the spell or effect. The barrier also extends into the Ethereal Plane, blocking ethereal travel.

If another spellcaster using the spell Zane's Unstoppable Force catches the barrier in its area of effect, the barrier is destroyed and all creatures within 30 feet of the barrier must make a dexterity saving throw against the other spellcasters spell save DC or take 20d6 force damage, taking half damage on a successful save. Creatures inside the barrier have disadvantage on this saving throw.
