CALIBRATION DICE: Is that a mingwave on the tip of your tongue? One standard size dice, engraved white on opaque black. $10 (USA) $20 (World)
Can't remember if it's a romawave or not?
Should you take the polywave or the xylowave?
Maybe a roll of GX Jupitter-Larsen's Calibration Dice is all the analysis you need?
(I will never call a dice a "Die" - just too morbid)
