Sorry I wasn't on the boards this weekend to help discuss all of your leveling questions. Here's some answers...
drothgery: Regarding prestige classes and the Turn Undead requirement on most divine PrC... I think I mentioned it some time last year... but I am completely flexible in regards to ignoring so-called "pre-requisites" when it comes to prestige classes. I care more about how they fit the character and the story than making sure the "right" feats or skill levels had been taken levels ago. So drothgery, although you've apparently already leveled Khalia as a 6th level archivist... if you have a PrC or two you might be more interested in, let me know here which ones and I'll go check them out to see if they make sense for you to take them now (and then you can rework Khalia as needed).
As far as using non-PH spells... that's absolutely fine. Please just do me a favor and write the spell info on your character sheet so I can see how it works.
stonegod: While I have displayed the floorplan of the temple, you are correct in that you haven't necessarily searched the building in it's entirety yet (I was waiting for the leveling process to finish up and the group to decide if they were going to rest for the night before forging ahead with the more intricate scouting of the temple itself.) One of the first things that will be done in that regard is the closer look at the main hall's fresco that Khalia and Donovan both know holds some important info (but they never got to really look at because the secret passage and the lizards in the altar room took precedence in the action queue). One the group decides to keep moving, we'll delve into where/how the advance of the temple will continue.
Mista Collins: I'm not sure I know the Quick Reconoiter feat. If you haven't already, please add it's explanation to your character sheet for easier reference. Thanx!
jkason: Any of those feats could work for you. Which book is your Sacred Healing feat from? Because as Autumn and stonegod said, the Sacred Healing from Complete Divine is different than what you mentioned. You also have Greater Powerful Charge available to you (from the Eberron CS), which would change your additional damage from 1d8 to 2d6 on a successful charge attack.
Also... it appears as though Unkabear has given up on the game. He's only posted a single time since I put out my "Calling Unkabear" post, and has done nothing since then. So I will assume that when the group continues on that Aern will remain "on-guard" in the main hall of the temple for the duration of this part of the adventure (in case Unkabear ever comes back). If we finish here and the group returns to civilization and he still hasn't come back... Aern will fade quietly off into the night.
You folks have been great! Hope the game's been going well for you. Please let me know here if there is anything you feel is missing or needs less of (combat, NPC interaction, puzzles, etc.) and I'll see what I can do. Thanx all!
