Ioun Stone of Protection

Requires Attunement
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 adds +1 to your AC.
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
AC 24 or a successful DC 24 Dexterity (Acrobatics)
check. You can use an Action to seize and stow the
stone, Ending its Effect.
