Ring of the Ring (Patreon)

Ring, rare (requires attunement)

This ring has a bell at its top, like a signet. While wearing it, you gain a +2 bonus to attack and damage rolls made with unarmed strikes, and on a hit, the ring emits a faraway "ding" sound.

Square Up. While wearing the ring, you can use an action to touch your two fists together, emitting a louder "ding, ding" when you do. When this happens choose a 20-foot square on the ground that you can see; you must be within the square. A series of magical walls that are 5 feet tall and 1 inch thick spring up from the ground around the square. A creature in the way of a wall must make a DC 15 Dexterity saving throw; a Gargantuan creature automatically succeeds on this saving throw. On a failed save, the creature is moved entirely within the square and knocked prone. On a successful save, the creature is moved just outside of the square. You can use a bonus action to make a single unarmed strike after using this property.

A creature can use half of its movement to climb into or out of the square. If the creature is Large or smaller, it must also make a DC 15 Dexterity (Acrobatics) check when it attempts to do so. On a failure, the creature falls prone just inside the square.

While within the square, your unarmed strike attack rolls score a critical hit on a roll of 19 or 20.

The square remains for 1 minute, until you fall unconscious or die, or until you end the effect using a bonus action. For the duration, creatures within the square have disadvantage on attack rolls made against targets outside the square, and creatures outside the square have disadvantage on attack rolls against creatures within it.

Once this property of the ring has been used, it can't be used again until the next dawn.

Those who enter seek thunderous applause. Those who leave settle for nothing less than total victory.
