I know WHAT it is, but I dont know why it exists, what use it has, or where it may have come from. All sides are identical, its translucent green. The pips are scalloped, not painted on, and are otherwise unremarkable. Help me out here, its definitely my favorite d6, but I am struggling to figure out a purpose for a +5 dice.
...I mean, aside from that I need a +5 weapon, clearly.
My guess is the magician rolls the forcing dice (perhaps after showing other identically colored dice for close inspection), instantly reads off the result, giving just enough time to see the top faces match what they said, then scoops them back up and moves on with the trick.
You might not get those two seconds.
