3.5 Armor values are pretty weird. I mean, just look at it! Some of them are just plain useless even in P&P; and most are not available in NWN as-is anyways, for example, the differentiation between a +6 Splint and a +6 Banded.
So the Silver Marches Rule Kobolds decided to rework them, and here is what they came up with.
Armor
ACP = AC - 2
ASF = AC * 5
| AC | MaxDex | ACP | ASF% | ASF% (Bards) | |
|---|---|---|---|---|---|
| Clothing | 0 | - | - | - | - |
| Light | 1 | 8 | - | 5 | - |
| Light | 2 | 7 | - | 10 | - |
| Light | 3 | 6 | 1 | 15 | - |
| Medium | 4 | 5 | 2 | 20 | 20 |
| Medium | 5 | 4 | 3 | 25 | 25 |
| Heavy | 6 | 3 | 4 | 30 | 30 |
| Heavy | 7 | 2 | 5 | 35 | 35 |
| Heavy | 8 | 1 | 6 | 40 | 40 |
Shields
ACP = AC
ASF = AC * 10
| AC | ACP | ASF% | |
|---|---|---|---|
| Light (incl. Buckler) | 1 | 1 | 10 |
| Heavy | 2 | 2 | 20 |
| Tower | 4 | 4 | 40 |
The keen observer will notice that tower shields are now AC4 instead of AC3.
We hope this clears things up a lot, and will make calculating things in your head simpler too. Our resident Drow has been volunteered for sacrificial testing. Happy bashing.
