But let's say I really, really wanted to do so, but with a minimum of extra rolls. How could I eliminate the extra attack rolls, while keeping the extra damage?
Here's an idea:
- Make the attack roll. If successful, find the last digit of the d20 result (0 through 9, in other words.) This is the limit digit.
- Roll all the relevant damage dice. If a given damage roll is greater than the limit digit from Step 1, that attack didn't get through. Otherwise, it did. Treat "0" as "no limit".
- At least one attack will do damage. If none of the damage rolls are less than the limit digit, use the highest damage roll.
So: a 4+2 HD lion attacks an archer in leather armor. The d20 roll is 12, which (using Target 20) is an attack result of 23, enough for a successful hit. The damage limit is 2 (from the actual d20 roll.) In Greyhawk, a lion uses a claw/claw/bite routine that does 1-3/1-3/1-10 damage. If you roll 1, 3, and 6, the lion makes one claw attack, but misses the second claw strike and the bite. If you roll 3. 3. and 6, none of the attacks are below the limit (Step 2,) so you use the highest damage (Step 3;) the lion bites for 6 points of damage.
