See, if you're reading this comic but have never played a roleplaying game, this is why gamers have those collections of more dice than you think they can possibly use. Because in the heat of battle, the dice will roll off the table and under the sofa.
Some gamers adopt a rule of "play the dice as they lie". But this can cause inconvenient pauses in play while everyone scrambles under the furniture to confirm whether the fireball did 28 or 37 points of damage, or the dwarf made his saving throw. Indeed, if a die rolls under something like a refrigerator, it can involve major moving work to observe the die without disturbing the number rolled.
The saner alternative is to declare that dice that roll off the table are void, and to roll again. And if the voided dice are somewhere difficult to retrieve quickly, it's better to just have spare dice.
Multiply this by 100 or more rolls in a really exciting combat. So obviously any gamer worthy of the title will have several hundred dice. It just stands to reason.
As a bonus today we present our original concept art for the Yoda-Dooku fight sequence. This art was done way back in October, 2007, when we were only up to strip #11! This set the concept for the angular, broken panel structure we now use in all laser sword fight scenes. Yes, we've been holding on to this concept art for two and a half years before the scene in question.
