For anybody with money problems, remember to sell old armor. You should have tons of shit from drops, more of each kind than you'll ever need.
I finished the Temple sidequest, and really enjoyed it. I can confirm that the result is 1x Shaman Mark for each Sister that you have in your party, but I'm not sure if it is based on your roster or your Warren Report status.
The battles were fun, the dungeons were the right length, some parts of it were pretty challenging, and I liked finally fighting some new classes (each Temple had one humanoid and one monster class that were enemy-only, i.e. no marks and cannot be recruited). I managed to get both crafting books out of each boss fight. Once you're done, all six dungeons reset, and you can re-do them without doing the annoying surface fort battles.
Why isn't this available in the post-game though? That seems really, really dumb.
There's gotta be a Pro-action code or whatever that makes Wootz Steel buyable. That would cut back the tedium in the crafting system sooooo much =(
