Archangel, you always get your first outfit for free. Just take the winter outfit.
Wood isn't rare. Most of them are, unfortunately, conifers, which is good for burning quickly, but not good for burning overnight, unless you have someone feeding it constantly.
Druids can Wildshape. I had a rule where you keep your stats whatever shape you are in a la Alter Self (I think it was in the Ephemera campaign), but I haven't added it to this game. If you guys think that it is fair, I could do that.
Hallack, no paragons (as far as everyone know, the paragons got smited something chronic at the end of the Age of War). UA alternative classes are OK. I don't think I have said no to that one. However, cloistered clerics would imply a monastery or temple of sorts that you spent your time studying stuff. In a world where survival is a day to day affair, I don't see that happening. That would violate the "no organisations" clause
No problems with the Endure Exposure invocation.
One of the guys described in the semi-intro is a druid, so yes, druids are allowed.
Hmm... MThor is underaged... That may cause some difficulties... Actually, it would cause some difficulties in the long run. I am opening up the discussion as to whether you guys are comfortable with that. Post-apocalyptic worlds tend to be... brutal. This one will be no different.
Shadowhunter, Touch is not a fixed range, unfortunately. That was established by WotC some time ago. Oh, and you get an extra bonus feat for being human, so you get 2 bonus feats total for being human. Level 1 humans get a minimum of 3 feats.
Metabreath feats will only work with breaths with a cooldown period expressed in rounds. Not even one with a cooldown period expressed in minutes will meet this prerequisite. This is explicitly stated in the Dragonomicon. However, Entangling Breath is NOT a metabreath feat. It is a breath channeling feat, which is something different altogether. It works as long as you meet two prerequisites: 1. You are dragonblooded. 2. You have a breath weapon. So, Entangling Breath will work with DFA's breath weapon.
