Today, we continue our look at the math behind MyD20 Lite for monster statistics. Today, we'll look at Armor Class. From my previous post in this series, I am using the Priest's attack rolls at each character level, including magic adjustments, to determine the base AC for a given Hit Die value, assuming that the average monster probably should require about a 10 on the D20 to hit it.
Table: AC Calculations
| HD | Level | Avg BAB | Magic Adj | Calculated Base AC | Smoothed Base AC |
|---|---|---|---|---|---|
| 1 | 0 | 0 | 0 | 10 | 10 |
| 2 | 1 | 0 | 0 | 10 | 11 |
| 3 | 2 | 1 | 0 | 11 | 12 |
| 4 | 3 | 2 | 0 | 12 | 13 |
| 5 | 4 | 3 | 1 | 14 | 13 |
| 6 | 5 | 3 | 1 | 14 | 14 |
| 7 | 6 | 4 | 1 | 15 | 15 |
| 8 | 6 | 4 | 1 | 15 | 16 |
| 9 | 7 | 5 | 1 | 16 | 16 |
| 10 | 8 | 6 | 2 | 18 | 17 |
| 11 | 9 | 6 | 2 | 18 | 18 |
| 12 | 10 | 7 | 2 | 19 | 19 |
| 13 | 11 | 8 | 2 | 20 | 19 |
| 14 | 12 | 9 | 3 | 22 | 20 |
| 15 | 12 | 9 | 3 | 22 | 21 |
| 16 | 13 | 9 | 3 | 22 | 22 |
| 17 | 14 | 10 | 3 | 23 | 22 |
| 18 | 15 | 11 | 3 | 24 | 23 |
| 19 | 16 | 12 | 4 | 26 | 24 |
| 20 | 17 | 12 | 4 | 26 | 25 |
| 21 | 18 | 13 | 4 | 27 | 25 |
| 22 | 18 | 13 | 4 | 27 | 26 |
| 23 | 19 | 14 | 4 | 28 | 27 |
| 24 | 20 | 15 | 5 | 30 | 28 |
| 25 | 21 | 15 | 5 | 30 | 28 |
Again, I'll have to make some changes to the Referee's Guide, but these are pretty decent values. A Warrior may find things ridiculously easy to hit at higher levels, and a Mage may suffer the opposite problem at higher levels, but this should work well over the range of most campaigns.
Tomorrow, we'll talk damage.
Hope This Helps,

Yep. I like these!
Originally, I think I used an average between a number of values, and this proved to be much easier. The difference in values isn't much, about two or three points lower at the upper end, but I like the end result better. This has been a very good exercise.
Tomorrow should be fun,
Flynn
