Gambler's Blessed Bones

{c}Requires Attunement
These magical dice have 6 charges per die, which
fully replenish at dusk. They can be used individually, as a pair or all three at once.
While attuned, you can use 1 charge per die to
decide what result will be produced before you
roll. If another creature uses the dice while you
are attuned to them, you can likewise decide the
result by expending 1 charge per die.
A creature can make a DC 15 Investigation or
Insight check to determine that the dice are fixed.
