The only problem I have with slaughtering entire towns is the concern that it might attract heroes of excessive power level before we're ready.<br/><br/>But in general, we'll need to repopulate the dungeon quickly, and low-level Medium creatures aren't going to cut it when enemy ACs are in the high 20s and the diceroller just isn't cooperating anyway.  We'll need a superior CR-to-space ratio.  (KOBOLD BARBARIANS WILL RISE!)<br/><br/>Jera, I'd argue that wiping out the point man in one surprise round (assuming he hasn't done anything really dumb) is a pointlessly obnoxious thing to do, at least when the party is made up of PCs, and hardly a worthy achievement.  And don't look at us like that -- we have not begun to fight!<br/><br/>All we need now is a few more giant fucking plant monsters...
