The Problem: Shields only give a +1 bonus to Armor Class
The Solution: ???
So, here's the deal. Shields are super important in combat, but not very important in the D and the D. My first thought is --- is this really that big a deal. Let's assume it is. So, what do we do about it? The most obvious choice is to bump the armor bonus from a shield. If you're going to do this, though, you should probably discount the armor bonus from everything else. Thus:
Leather armor: -1/+1 to AC
Chainmail armor: -3/+3 to AC
Platemail armor: -5/+5 to AC
Shield: -2/+2 to AC
Since that solution is simple, reasonable and easy to implement, I feel as though I'm ripping people off with this blog post. As a penance, please enjoy some unarmored, two-weapon wielding cheesecake by RGUS.
Side Note - Is anyone out there running a play-by-post with the DCC RPG beta rules? If so, let me know. I'd be interested in trying it out.
Side Note II: The Quickening - I should post a Megacrawl 3000 update later today, more Yun-Bai-Du (with a map) tomorrow.
