You conjure a wall of magical, iridescent bubbles at a point you can see within range. The wall can be up to 20 feet high, 30 feet long, and 1 foot thick. The wall is opaque and lasts for the duration.

Any Small or Medium creature that attempts to move through the wall must make a Strength saving throw. On a failed save, the creature is trapped within a bubble in the wall until the start of your next turn. Large or larger creatures are not affected by this trapping effect. On a successful save, the creature’s speed is halved for the rest of its turn.

When a spell or attack that deals radiant damage targets the wall or passes through the wall, the wall reflects the spell or attack back at the caster or attacker. The reflected spell or attack targets the original caster or attacker, using the original attack roll and spell effects.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the duration increases by 1 minute for each slot level above 5th.
