Thanks!
Seems I need a sleep! a day later I managed the part.

Now I finished this area and the game ED.
I only kill the trees until the way to the portal is open. Jump to the dragon tower to heal with potions sometimes.

The next part of the game is much easyer. (in easy mode!)
Seems in the easy mode they only make the human figths easier not the dragon figths.

Now I start the second story. FoV Lets go!
