Munchkin Apocalypse Questions

[Enzzo]

We just had our first game of Munchkin Apocalypse, and it was a lot of fun! Love the humor, love the difficulty! It also generated a lot of questions :)

1. Does Paranoid give you +5 when the 7th Seal is opened?

2. Do I get to roll for my Classified bonus when the 7th Seal is opened?

3. When turning over History Repeats Itself!, the top Disaster hits all players unless it's a global effect like "Open a Seal", in which case it is only applied once, correct?

4. I understand it's only usable once per turn, but can you use the Scientist's Atomic Transmutation ability at any time before the Charity phase on your turn, or does it have to be immediately before the Charity phase (e.g., could I use it during combat maybe? Or before Kicking Down the Door? Or do I have to wait until after combat/looking for trouble/looting the room?)

Thanks!
