My kid had this elvish d20 from q-workshop and free rpg day. It disappeared. A few months later I was digging in the freezer and out dropped that d20.
He put it in there hoping that it would 'learn' that 20's should appear more often.
One other time a friend and I went through my households collection of small soup pots to find the right one to boil his dice.
None of it works. It was fun.
As Gamers, we are at the whims of luck and probability. Dice, our tools, are woefully fickle and can have streaks of bad luck.
What do you do with your dice to keep the luck good?
What do you do if the rolls go cold, and how do you get the mojo back?
