For example, many people like to roll particular dice for certain types of rolls, or particular colors of dice for different armies. Some people don't like others to touch their dice, since they might rub their bad luck off on them. Some people don't like using the same set of dice for two consecutive rolls, always grabbing some "fresh" dice for a new roll. I'm sure there are countless others. Here are some that I've found myself believing in:
- Never roll one single die for anything, if it can be avoided. Out of every roll you make, there will almost always be at least one "failed" roll. So if you roll a single die, it will almost certainly fail. Because of this, if there is one weapon different in a squad, I roll all the dice together and use a different colored die to represent the single weapon, and I always wait until all attacks have been resolved so I can roll all the armor saves together, instead of one at a time.
- Conversely, once you start rolling a large number of dice in a single roll, more than 15 lets say, you dramatically increase your chances of rolling really badly. So if I have a lot of dice to roll, I'm better off rolling them in multiple smaller batches than all at once. One of the batches may turn out to be a really bad roll, but it's unlikely to have multiple batches rolled consecutively to roll really badly. For this same reason, anything that allows re-rolls is much more valuable in my mind than it should be.
- Never say "anything but a one", or something similar, before making a roll. You might as well not even bother rolling at that point, you're going to fail.
- Models that are pointing always do well. I have no idea why this should be, but it is.
- Any newly painted models are going to get killed. The more pride you have in the paint job, the more spectacularly embarrassing their battlefield performance will be.
- For some reason, for really crucial rolls, I like to use dice that were sitting with the 5 side facing up. This seems to come through for me pretty often. Something about the die being used to a high number facing up, and wanting to return to that state.
