The pain, torture and writhing agony have finally been overcome, in a not so dramatic fashion. Today Ordrak fell.
Normally I wouldn't waste time posting personal triumphs, and I realize many, many, many players have already achieved this goal, but for me it was so damn frustrating getting a Vanq to a level competent enough to survive Zealot's and other one-shot monstrosities I figured I owed it to myself.
My Vanq ended up being 47 before I finished off the main quest, but I figured since I had no plans to continue playing her after that and I seriously didn't want to fail in my mission, I might as well level her as far as I could patiently do so and still leave some amount of potential to fail. Well, outside of 2+ zealots simultaneously nuking her with lightning attacks there wasn't much chance of her dying unless I did something incredibly stupid. With her Electric Resist at 544 when buffed Zealots drained about 15% of her health if they managed to drain any, with their nuke. Ordrak himself caused little damage, occasionally when casting minions the game would force her to run up (a very annoying and potential game ending bug) and he would hit her with his cold attack for about 15% of her health from time to time.
