I failed to address the searching.

Five of the cultists were this, possessing equipment as such (minus 1 potion, and all "holy" items being unholy).

The sixth was one of those, only advanced. His equipment is identical, except the potion is moderate wounds, and his breastplate and longsword are both masterwork.

I don't imagine you can carry all of that, so let me know what you choose to bring with you.
