So I am stuck on the last part where you drink the poison. I'm veteran rank 8 and no matter what I do I cannot do enough damage fast enough to defeat these guys. I've tried everything I can think of and even googled the quest and tried things they suggested and I still cannot do enough damage. Someone suggested you try an challenge ones with bows but the guys I am facing none of them have bows, they all have dual wield. Can I skip this quest and still complete the zone? Or is it an important part of the main quest?
