Adventure mode (questions, solutions, hints, etc.)

[Sammual]

You can get the 2nd rage creature as soon as you get the box.
The 1st on requires you to be able to win a tough fight (On Hard as a Mage it is tough).
The 3rd rage creature requires you to get to an area that involves fighting a level 15 hero with a average army for that level so I don't think you can beat it on med until 12th level at the earliest.
I have not gotten the 4th rage create at 16th level yet.
