A Few Questions

[Viladin]

1. Retroactively applies to flat level things.
2. No.
3. Yes.
4. It progresses up to 10th level and stops. For example, if you took Black Mage spelllcasting at 4th level, it caps at 14th level.
5. Exotic WP counts as a feat, so 10 JP.

Now that my brain's had time to percolate it my munchkin brain comes to the fore again: 

How does Jack of All Trades apply to single talent things that scale by level? Like the Martial Training or Canny Defense. 

How does it apply to things like a Ninja's Ki Blade talent (which I think is a single purchase AND scales automatically, win!) 

Or the Stamina Talents that scale automatically like Control (+1 to hit, +1 per 4 <strike>Sword Saint</strike> Freelancer(!?) levels). 

If I'm using Jack of All Trades and pick up Stamina from Sword Saint at level 1, can I pick it up from an archetype at level 11 to keep it going for another 10 levels, or does it stick with it for all 20?


((I probably won't use Jack of All Trades to avoid getting rule books thrown at my head, but Inquiring Minds Want To Know!))

1. Again, it stops after 10 levels have passed.
2. Same as above.
3. Same as #1.
4. No, you cannot pick up Stamina Pool again.
5. Adamantine stacks with Battle armor.
