My last thoughts on the subject of damage dice in Dungeon World. I have shared my spreadsheet in the previous threads. Below is the thing I will put on a bookmark or GM screen for my own use. It shows the median (rounded) in the middle, with a standard deviation on either side. If you go out two deviations, you are basically looking at the min/max of the die size. Knowing that, you have five no-roll damage options for each monster min, light, average, heavy, and max damage. My impulse would be to apply average damage on a 7-9 player roll and max damage on a 6- player roll, and to actually roll the damage only when it could reduce the player to 0 HP. I will likely use the light damage when it makes sense narratively: a monster is getting its ass kicked and is on its heels, is beset by multiple foes, or in combination with one of the monster’s moves. Regardless, the graphic gives me an at-a-glance way to tell how much damage a damage die configuration (especially the best of 2/worst of 2) would likely do.
