Cage Bubbles

Potion, rare

This flask of effervescent fluid can be hurled at any point 30 feet, shattering and releasing an eruption of tiny, floating bubbles of force filling a 5-foot cylinder, 15 feet high, lasting for 1 minute. This area is treated as difficult terrain, and any Large or smaller creature within the area must make a DC 14 Dexterity saving throw.

If the saving throw is failed, the creature is restrained and cannot move within or leave the area of the cage bubbles. However, these tiny bubbles of force also provide three-quarters cover against attacks into, out of, or passing through the area.

Large creatures only partially within the cage bubbles have advantage on this saving throw, while Tiny or smaller creatures have disadvantage. A creature inside the cage bubbles use its action for the round to attempt to break free with either a Strength saving throw or Dexterity saving throw.

The cage bubbles are constantly swirling, popping, and reforming, and this distracting effect causes creatures within or adjacent to the cage bubbles to have disadvantage on Wisdom (Perception) checks and on Constitution saving throws made to maintain concentration.
