I’ve been working on B/X combat using a grid and testing some things, using the Caves of Chaos in B2: The Keep on the Borderlands. I keep a stack of characters on 3×5 index cards ready at all times, and I grabbed a few randomly to use for the solo play-through.
As most who have ventured into the Caves of Chaos are aware, one rarely gets out of there clean. Though my solo test party has fared surprisingly well so far, they did suffer a loss against some of the goblins, with the party’s fighter falling during a particularly nasty fight.
Adding a sting to the loss is the fact that the character killed was one of the first I rolled up for my stack of cards quite a while ago and the token I used for him was one of the first I created, meant more as a test than for actual use.
If it makes you feel any better, VerHagen (wherever you are), the normally-reserved halfling archer pretty much berserked when you fell, slaughtering the remaining goblins in a fit of rage and despair. The rest of the party had never seen her behave like that before, but she didn’t really want to talk about it afterwards.
