Wondrous Item, varied rarity, Requires attunement
A Jhunal stone is named after the Nordic name for the god Julianos, got of Wisdom and Logic. Many types of Jhunal stone exist, each type a distinct combination of shape and color.
When you use an action to toss one of these stones into the air, the stone orbits your head at a distance of 1d3 feet and confers a benefit to you. Thereafter, another creature must use an action to grasp or net the stone to separate it from you, either by making a successful attack roll against an AC of 24 or a successful DC 24 Dexterity (Acrobatics) check. You can use an action to seize and stow the stone, ending its effect.
A stone has an AC of 24, 10 hit points, and resistance to all damage. It is considered an object that is being worn while it orbits your head.
