Crystal Dice (Artemir's)
A pair of crystal lucky dice
The dice are a crystal set of dice that are connected, and when viewed always total 7 across their faces.
The dice have appeared in a variety of tales, but common traits seem to allow the person gifted with the dice Artemir’s favor (increased luck) and some sort of communication with Artemir. Often they are said to allow the person holding them the means to unlock doors, items, or some other means of quick escape.
