@S'mon: How do the players feel about it? Are they bitter or did they think it was awesome?
It sounds great, the stuff of legends anyway. Hmm a whole orc tribe. So close...
I wonder if the players have learned anything from it? I wonder if a PC drops is it time to sound the retreat or maybe - glup - surrender?? Or parley, play for time.
Some discussion here:
4e D&D - Raven's Wing: Vault of Larin Karr (full) - 12:30pm-ca 5.30pm fortnightly Sundays, next game 7th February - The London Dungeons & Dragons Meetup Group (London, England) - Meetup.com
I have tried surrendering in a 3e Midnight game, to save another, downed PC - it worked for me, I later escaped, but the other PC still died during a bungled rescue attempt by the two PCs who'd escaped the initial battle.
This time AFAIK it didn't occur to the players to surrender or parley, probably because the fight still seemed winnable until the end. Maybe next time? Given how close it was, the orcs might have been amenable to parley at the right moment. I think the blood lust was running pretty high on both sides, though!
