I was curious. We've had larger battles take 2-3 hours in real-time and maybe 15-20 rounds in game time. The other end is also true, 2-3 rounds in about 15-30 minutes. I know what you mean about the lengthy process of reducing overblown PC hit points, though. However, by Tier 3 there are a lot of decent damage monsters where 4-5 hits will take a PC out.I wish I knew, but I almost never track combat rounds.
