Ioun Stone (Awareness)

You can't be surprised while this dark blue
rhomboid orbits your head.
Another creature must use an action to take the
stone, either by a successful ATK vs AC 24 or
DC Dex (Acrobatics). You can use an action to
seize and stow the stone, ending its effect.
Stone has AC 24, 10 HP, resistance to all damage.
It is considered to be a worn object while orbiting
your head.
