So again you're looking at 14-17%.
To do this properly we would need to make assumptions about the frequency of various weapons and armor types and hence the frequency of target numbers in play. This would likely be a campaign-specific thing, particularly regarding fantastic combat. There is unlikely to be one perfectly correct answer for all contexts.
Agreed.
So, while all the various methods of determination will have their specific merits, simply doubling d20 adjustments for the 2d6 context seem to me to be the most acceptable general use solution. YMMV and that is fine too.
Agreed again.
Keep in mind the following distribution of AC in Monsters & Treasure (not counting Men, counting Horses and Mules once, including the different ACs for Lycanthropes).
AC / Count / % of total
AC 2 x8 15%
AC 3 x7 13%
AC 4 x8 15%
AC 5 x12 23%
AC 6 x9 17%
AC 7 x4 8%
AC 8 x4 8%
55% of monsters fall in the range of AC 6 to AC 4. (28% AC 3 to AC 2, 16% AC 8 and AC 7.)
Of course, the frequency of these monsters/ACs is at the discretion of campaign referee.
AC 6,5, and 4 on the Individual Missile Fires table are categories 4., 5., and 6.
4. 5. 6.
7-8-9 8-9-10 9-10-11
6-7-8 8-9-10 9-10-11
6-7-9 8-9-10 10-11-x
5-6-8 6-7-9 8-9-10
5-7-8 6-8-10 8-10-11
5-7-8 6-8-9 7-9-10
Ranges of these weapons are as follows.
15 = 150 = 50/100/150
18 = 180 = 60/120/180
18 = 180 = 60/120/180
21 = 210 = 70/140/210
24 = 240 = 80/160/240
24 = 240 = 80/160/240
Missile fire, if it happens at all in dungeons, will most likely fall within the short and medium ranges.
A quick calc for a target number for each AC, taking the median across the 18 numbers for the six weapon entries:
AC 6/#4 = 7
AC 5/#5 = 8.5
AC 4/#6 = 10
A quick calc for a target number for each weapon, taking the median across the 9 numbers for the three AC entries:
Short Bow = 9
Horsebow = 9
L xBow = 8
Long Bow = 8
Composite = 8
H xBow = 8
A quick calc for a target number, using both quick-calc methods above, but using just short and medium ranges:
AC 6/#4 = 7
AC 5/#5 = 8
AC 4/#6 = 9
Short Bow = 8.5
Horsebow = 9
L xBow = 9.5
Long Bow = 7.5
Composite = 8
H xBow = 7.5
Again, a bunch of 7 and 8 results, with some 9s to consider.
My guidance to referees would be to use the following substitutes
+3 for +1
+5 for +2
+7 for +3
and not to worry even if the modifiers were
+3 for +1
+6 for +2
+9 for +3
I don't think this breaks much, if anything.
The caveats here being, this is largely for missile fire using the Alternate Combat System in a way that is trying to replicate the feel/results of the 2d6 Combat System.
But I think a campaign would run just fine, and replicate Chainmail combat a bit better, if the modifiers were introduced in 1d20 melee too.
As Starbeard recently noted, the grade inflation that happens (at the least) to damage inflicted from the LBBs to Greyhawk (and onward) is likely in response to the ever-expanding time it takes for higher level, larger groups of combatants to actually move the needle in real time.
I can see one element that contributes to that is the application of small modifiers in the LBBs (perhaps lingering from Chainmail) to a 1d20 scale, making hits less frequent.
