Koplow Games Character Builder Loaded Dice
Brand: Koplow Games

This is a set of three loaded six-sided dice weighted to roll sixes, specifically designed for rolling up 18 stats for your Dungeons and Dragons characters. Let's be clear here: when you use these dice to roll a Dungeons and Dragons or Pathfinder character, you are cheating. Blatantly and flagrantly. There is no excuse for this, except possibly if your GM is evil and cheats as well, killing off characters unfairly, and using these loaded dice is just the next step in the escalation that will inevitably lead to rage-fueled table flipping, dice throwing, and eventual man-hugging as you become cool with each other again.

These are standard-sized black six-sided dice with silver pips for numbering.
They are numbered normally, but are weighted so that they're more likely to roll six.
They won't always roll six, but are far more likely to.
In general the longer they roll, the more likely they are to land on six
With a little bit of practice you can pretty frequently get a natural 18 on a roll of the three.
