Well, a couple things, to answer questions:<br/><br/>Yes, you'll gain a significant standing in the region by completing this major quest; the ultimate goal being whatever you might choose, since I'll open up goal paths to you, in the future.<br/><br/>I don't know about CR6, but I do know there's some CR 12 with Disjunction. At will.<br/><br/>I'll be both leveling you soon, and granting you the ability to recruit a Lieutenant; a special minion at your level -1 (1 per dungeon, at first), with 2 actions per day. So, not only will your minion level cap raise to 7, you'll have your CR 8 Lieutenant.<br/><br/>Fuck will-o'-the-wisps. Six of 'em nearly killed my tenth level party. I mean, an insane AC, touch attacks, and immunity to nigh-everything? Of course, you'll have trouble with them doing any sort of excavating or building. Make it real nasty? Give it rogue levels. "Suddenly, a small ball of light stings you from behind for... 47 damage."
