I just attempted Echoes of Oblivion, and couldn't get past the Valkorion boss fight. I couldn't target the adds, Satele died early, and Valkorion's health recharged every time it got low enough to give me hope. Mine did as well, so I couldn't die. After half an hour, I went and jumped to my death just to end it. So I suppose I should ask, how did anyone beat it? Is it just a matter of continuing to slog through and attack him, or is there a way to destroy the adds? Just getting frustrated here.
