We finally saw some combat, so I wanted to take a moment to give a quick after-action report.
Our intrepid adventurers only made it through the first few encounters of this location. Because of some bad planning, however, my daughter's character got caught out alone approaching the front door. The battle/mad-dash-back-to-her-group that ensued caused her character Ella to face two opponents alone for a couple of rounds.
She was quickly reduced to 0 HP/MP (actually, she was reduced to -10...but not with these rules!) We consulted the Death, Dismemberment, and Injury chart. She rolled a 12 - Minor Injury! I asked her to roll a d6 to see if it affected movement - a one in six chance. She rolled a 1 - so movement was affected by the injury. I used these results to narrate how her opponents the large sword crashed flat side of the blade into her lower leg, breaking her tibia.
In the second round, one of the opponents was wrapped in a rope (Rope Trick FTW!) so only one could attempt strike her - and it was successful. Since she was still at 0 HP, instead of damage, we again consulted the Death, Dismemberment, and Injury chart. This time she rolled a 15! Lucky Girl! This meant she was stunned. A couple of d6 rolls to determine if she was knocked down - she was - and/or knocked out - she was not. Again using the results to narrate, I described how the weapon crashed awkwardly into her helmet and brained her but good.
So when her group finally caught up to her and dispatched the opponents, she was lying on the ground, head shaken, with a broken leg.
This is where things got dicey. At the last minute, to mesh these rules with DCC (they were originally written for a 0E-ish game) I added the column representing the number if dice needed in a Lay Hands On attempt in order to heal each category of injury. We have two clerics in the party - one of them the character that had just been injured. Between that and the rule book, there were three different sets of numbers for Lay Hands on results - each character sheet was different and both were different than the rules. I sorted it out and we proceeded.
The first attempt failed. But the second attempt - a bit later - did the trick and her bones were miraculously mended.
Thoughts: it did not slow down play at all in the midst of battle. What caused us more of an issue was the recovery aspects. There were other basic HP loss situations that occurred with other characters in the next few encounters - but they soon reached a point to barricade for an hour and rest, so they all got a recovery die back for that. The largest question I see is - between miraculous healing of injuries and complete rest - how fast does one regain hit/miss points? What does it take? That's what I'm kicking around at the moment....
