I have a question for you all along similar lines:
In our current campaign we were ambushed by a small party of drow, nothing challenging really, Between Crossbow bolts that have a vial of Alchemist's fire built in (mine), the Lightning bolts (party wizard), we were able to create alot of light, which really helped us out. Anyway, we've picked up a paladin in our party. My elven Rogue is Chaotic Neutral and after turning a pair of drow into torches, I decided to help out the Paly. I hamstrung the drow he was fighting, during that drow's next turn it hacked at me while prone, My next turn I elected to bash it in the face with the basket-guard of my rapier to knock him out (we needed information).
The Paladin promptly condemmed me and told me that I shouldn't have done that ... Anyone else see something weird about that? Sure I struck a prone foe, but at the same time I did the most life preserving thing possible...
