Some creatures, particularly Chaos aligned ones in the Elric setting, only take half damage from mundane weapons. I know this is probably a stupid question but I'm writing up a Dungeon Crawl and I got to thinking: Is it only the hit point damage halved, i.e. the damage after armour reduction or is the rolled damage halved and then applied normally? As an example, I attack a monster with 4AP that only takes half damage from my weapon, I roll 2D8 +1D4 for my damage (Greatsword) and get 10 points, how much hit point damage does the monster take (assuming no CM's), 3 or 1?
