Paladin in Citadel raises an excellent point about shields and J.D. Higgins suggests a pretty good fix. Blogger ate my comment so I’ll comment here.
I think I’ll stick with the “Shields shall be splintered” rule tohugh becaue I am running a vaguely Nordic campaign and Viking shields were light and fairly disposable. In the sagas, anyway, shields WERE splintered. A lot.
My other hesitation about Higgins’ table is that mail and plate armor really were strong defenses too and should not be underestimated. By the time of full plate armor, no one bothered with a shield if they had plate. So I’d go with sometihng like this (swapping ascending AC for descending):
- Unarmored: 10
- Leather: 12
- Shield only ; Mail: 13
- Leather & Shield: 15
- Plate/mail; Mail + Shield: 16
- Plate/mail + Shield; Full plate, with or without Shield: 18
So there would be diminishing returns on a shield for platemail and no return on full plate.
I’d probably also consider allowing a shields a save (say, d20 vs. 9+damage stopped for metal, 12+damage stopped for wood) against splintering, but then decrease a shield’s AC to +1 again. Or sometihng along those lines. Becasue enhanced AC WITH splintering would make shields too good…
