This week, the group picked up their teeth and moved on to the kobolds lair. They were short both of their high-perception characters, the players were out of town, but of all people the Paladin made his passive check to hear the kobolds making conversation. That was the last thing that went really well for them. Instead of anyone rolling Perceptions, they decided to charge through the trees and attack the unseen foes. (good thing it wasn't a merchant caravan or something.

) I did mistakenly charge the Slinger into melee along with the Minions, so he wasn't able to go in and warn Irontooth. but heavy wounds were suffered and at one point the Warlord, the only Leader in the party went down. They did manage to pull out a win, bringing down the Dragonshield as he was trying to get to the lair and warn the others.
After a short rest, they entered the lair. Trying to stealth this time, but the first roll made was about an 8.
I have a much better handle on kobolds now, and monsters in general, I think. So this was very much a running battle. The party was able to eliminate Most of the minions, before IT came out to play, but the Skirmishers were still on the board. Add the other heavy hitters and IT himself and what we had was a potential massacre. PCs started dropping like flies, and I was even trying to be nice. I dropped, both Warlocks, had the Wizard running for his life, and the Fighter bouncing back and forth between bloodied and not. My dice were HOT. Everyone else’s were rolling badly, indeed. Even the fabled 'Red die' of the Paladin (AJ, the UGT owner) was rolling badly. In the end, the party won out, but not before suffering their first loss. One of the Warlocks failed three saves in a row. D E A D.
We moved on to the next encounter, This one was really pretty one sided. After not falling for the trap, the party moved immediately to take out the Slinger. He got one volley off nailing the Warforged with 2 of his 3 shot burst. (Surprising the heck out of the party, "He had
three shots???"

) The rest of the enemies went down quickly to very well coordinated maneuverings by the party. Under the blankets in the pit, they found not only the Warlord's missing mentor, but a Half-Elf Cleric, who gladly joined the party. Now with two healers in group, they should fair much better.
After the session, I made a very important decision as to the progression of the campaign. I will not be using the 'every one has the same xp no matter what' rule. That one really bugs me. Sorry, but if you aren't there, did not contribute, why should you receive the benefits? But at the same time, I decided that dying PCs replacements will get xp for the encounter which killed them.
