Hi...I'm a lv 60 huntress...i found that it's not that hard like u guyz said (or it's just me). it was soloable. i completed the quest by solo just now. here's what i did:
1. kill all the surrounding bugie bugs...
2. then, when all the bugs were killed, make sure ur mana is full. after that, put a freeze trap, for precautious (although it wasn't use after i put the trap.) then order ur pet to tank...use VIPER STING on her. then keep shooting her. by the time her mana's out, it'll b piece of cake. just keep VIPER STING her, dun let her spirit gain her mana, or she'll keep healing herself. try it... hope u can complete the quest...^^

n.b: sory for my bad English, i'm Indonesian...^^;

Good Luck...
