I just lead my first at-level Chrono using this thread as a guide. I had been in loot-run Chronos before, of course, and even a couple eChronos, but could never find a party for an at-level run on one of my lowbies. I had a lot of fun, and it seemed like most of my group did too -- and we were successful! Levels 4-7, no xp penalty. There were a few deaths (one character had less than 40 HP, and I just couldn't quite keep him up all the time), but overall it was quite smooth!
Anyway, I just wanted to thank you for this fantastic thread and maybe give it a much-deserved bump.
I have a TR'd Artificer at 6th level right now and this seems like an interesting thing to try out when I hit level 7. Preferably I'd try to get people I know with me since I've seen level 10+ die quite easily to mobs on elite.
But this seems like an interesting challenge that you don't see that often!
Awesome, awesome, awesome, super awesome thread.
