Counts as good or evil for the purposes of negating resistances as necessary. So you have a Baatorian Green Steel dagger, it counts as magical for the purposes of overcoming resistances or affecting vulnerabilities.
I like both of those.
You're evil you know that right?
I do try. If the DM isn't at least a little evil, especially when you are in hell, it's no fun. One of my crowning achievements as a DM (From my point of view) came from that adventure as the party actually started planning a trip back to help get an NPC I created out of there.
