I am a level 16 rogue, and saw videos of people clearing Call of Blood at lower levels, so I was sure I would be fine. But I can't even kill the first 2 Stormknights after provoking Dobros. At the start of the battle, I have my rogue and Grissenda take Potion of Lesser Shielding, and then I have my rogue do Evasion, but it seems like I do very little damage (armed with an Icicle and a Flaming Hatchet) and can't take healing potions quickly enough. They make short work of both of us. Is this quest just too hard for a rogue of my level? Am I doing something wrong?
