I had to level up till i was at lvl 26. I went to brokenVally and took out the dragon defences and a couple teams of black ring, got out of there before they could screw me over (gotta love the D-stone), then did the same to a couple of the flying fortresses. (not that i can defeat the bosses).
The imps would have been impossible for me along the beach at a low level as there is just so many.

Let us swim in this sea of fire, and hope that the demons of doubt do not drown us.
