Ten d6 in D&D
- Fireball and Lightning Bolt do 8d6 from a 3rd-level slot and one more d6 for each slot level above that, so a 5th-level slot throws 10d6.
- Sneak Attack reaches 10d6 at 19th level, the most it ever gets.
- Disintegrate is 10d6 + 40. Set the modifier to 20 and add another 20 in your head, or type it into the dice generator.
With ten dice the total is very predictable: it lands between 29 and 41 about three rolls in four.
Dice pools
Pool games roll a handful of dice and count the ones that hit a target instead of adding them up. In Shadowrun, each die showing 5 or 6 is a hit, so ten dice give about 3.3 hits on average. The roller shows every die, so you can count your hits straight off the result.
Even more dice
This roller goes up to 20 dice. The main roller takes bigger mixes and saves the ones you use every session.
