This is the point you definitely have to decide what class, and start thinking on what race you'll want to use.
In my case the class is the Healer. The game names it "priest", but i refuse to relate anything religious to me.
So, the prime problem in this stage - aside that every campfire takes 3 battles - are hit&run centaur archers. They hit hard AND stay in an unreachable position.
MY solution was to use beasts with Blessed Armour cast on them, staying totally protected. For firepower archers were used.
The necessary beasts were aquired from Challenge Hall rewards.
The area can be done reliably so to say, although with barely any HP remaining. Better-then-basic equipment also avaiable from Challenge Hall rewards.
