You need to train your dice. When they are just sitting there waiting to be used make sure they have the largest number on the die facing up. Dice have a "memory" and this will become their natural state resulting in the die wanting to go return to this state as often as possible.
Also before you roll rub the lowest possible number on the dice on whatever surface you are rolling on a few times. This makes a slight attraction between the lowest number and the rolling surface usually preventing major botches.
If all this fails to improve your dice rolling place your dice high side up in a ceramic bowl of purified water under the direct light of a full moon for exactly the number of minutes as the highest number of the die. This works every time but requires a recharge every time there is a full moon or your dice will be cursed.
If you are truly desperate mix two drops of you own blood with a melted white crayon and dip the dice in this mix completely. Then put them in a box where absolutely no light will touch them for a full week. After a week has passed gently remove the blood/crayon mix with a piece of never before used 100% wool cloth. After wiping off the mix submerge them in a glass with balsmic vinegar and distilled water at a 3 to 1 ratio. Let them sit for exactly 7 minutes. Then roll the dice 7 times each individually, then 7 times collectively. Finally dry the dice with a new and unused piece of 100% cotton cloth. The dice are now primed and ready to destroy your enemies.
Good luck.
