Barry's Stat Device

A strange device found in a dungeon years ago. Once attuning your 'aura' to it, it has the ability, twice per long rest but not twice in one battle, to add +3 to a roll or saving throw of Strength, Dexterity, or Charisma. It cannot alter one's constitution or intelligence. 

Notes: Should the area be devoid of magic, such as a forest without a mage in the party, the device won't recharge., You have to have your 'aura' linked to the device.
