What happens if a PC has an item that makes their stat always X but that stat is drained ?

@Mentalburnout @SageAdviceDnDWhat happens if a PC has an item that makes their stat always X but an enemy has an effect that drains said stat? canonical answer would be from @JeremyECrawford – I would reduce stat from item's value

@Mentalburnout @SageAdviceDnD if you attune to the item again, restores stat to item's effect
