The thing about the Doombringer's area... I kept getting my tail handed to me and was not sure WHY... until I realized that I was level 24 and the foes were level 29! I went back to the Blackdagger Ruins and ran around the forest until I was like level 26 or so and went back and fared much better.
I solo'd to level 50 during BW #3 with a cleric companion, aka aggro-magnet sacrificial-lamb. She ALWAYS died. Well, 'got knocked unconscious'... but she managed to live long enough for me to win most fights.
Only fight I gave up on was Captain Kayliss... after four attempts I was too frustrated to try again. She was the SAME level as me, but she spent no time whacking my cleric and the Bait and Switch shadow melted away almost instantly so it was just ME. Beginning to think some MOVEMENT bonuses in gear might be handy for those fights. :P
