Silver Dice with Red glowing Numbers

Wonderous item, relic

These are 2 silver six-sided dice gifted by an unknown man in green rags.

Once per day the numbers on them glow a deep crimson red and if you roll them, they roll themselfe again

Both roll, higher total wins, two succesive numbers beat any total number, two higher succesive numbers beat lower ones (3-4 beats 2-3) and two of the same beat any succesive number but two of the same higher numbers beat the lower ones (3-3 beats 1-1).
