I'm having major trouble getting pass the first part of this quest :/ and it's getting to be super frustrating.

Any Bards finish this quest? I can't do it :/ Almost always less than a minute into the fight, I've lost 10 tactical rating, then it just builds up, are there specific targets I am suppose to kill first in some order? my team seem to die super quick, the whole first part of the quest feels like it's out of my control :/

Any advise/tips? this is really frustrating. Or is my Bard just screwed for this quest forever :/ Should I not have Wanderer's Minuet? is my attack just too low as a Bard for this quest :/ I'm i196
