I ran the module last night, and there were three deaths out of 4 PC's. Never underestimate the compulsive power of revenge. After the first encounter, the Eladrin Ranger began to track the enemies back to where they came from (impromptu skill challenge, 5 successes before 3 failures, DC 20). He succeeded, and took the Dragonborn Paladin, Tiefling Warlord, and Half Elf Warlock along with him.

They handled the group of Kobolds outside the waterfall well, but suffered minor damage. Healing Surges after the combat brought them back up to full, however. The Ranger noticed a kobold spying on them from around the edges of the waterfall and the group charged in.
This is where it got nasty.
The minions had formed a line and on their initiave all threw javalins at the PC's as they came through the water. Spurred on by two of the Dragonshields and the Skirmisher, they quickly surrounded the PC's and started plinking heavily at them. Eventually, the Wyrmpriest arrived and let every bad guy shift and gave them temporary hit points to boot.
The PC's soldiered on, almost robotically dispatching minions and bearing down the enemies.
When they finally killed the last visible bad guy, the horn sounded and Irontooth made his appearance with the last Dragonshield. I played it very strategically with both of them using their free shifts to surround and flank enemies, but even then the fight was going to the PC's until they bloodied Irontooth.
Then he killed two of them on his action.
Bam. Bam. Just like that. 1d8+1d10+4 with a +8 to hit, he dropped the Paladin and the Warlord as they were flanking him. The Dragonshield shifted to the Warlock, and followed him when he tried to shift away, then dropped him when he tried to use Eyebite to help himself get away. The Ranger, seeing this, ran.
And honestly, I don't blame him.
The corpses of the PC's will now be used as descritive elements when the new group who joins up with the ranger makes their way to the Head Priest. I think it's a suitable end for them. All-in-all though, it went better than I thought since they were just 4 PC's at first level in a Level 6 encounter. As one player put it, "Not feeling like you're a first level PC is both the most awesome, and most dangerous, thing about the new system."
