Question about handling huge trash mobs as Drk.

[SummerScorcher]

At lv63, I'd say you're doing well. As you level and get Quietus/Enhanced Blackblood/The Blackest Night, the trick is to use your single target weaponskills as little as you can; keep the mp flowing, Dark Arts + Abyssal Drain, DA + Quietus if you know its gonna cap your MP, and at lv70, make sure you always have mp for your next The Blackest Night- so you can repeat the cycle of Blood > MP > Blood > MP etc, etc.

As for Passenger, I generally avoid it unless I'm about to cap mp/theres at least 4 mobs. MP's better spent for Abyssal Drain. The DA blind is nice but isn't worth 50% of your MP bar.
