there were never string vs. wind arguements.
Wind > for acc
string > range/AoE
singing > you....rather simple. this is a endgame must have w/o question for brds.
I've been duoing this with a friend, 75SMNx2. We take Kotan to Pixie Island (F-5) and kite it around the 'lake'. With the dip it's very easy to kite on any job without movement speed. So far we are 1/12 9 of which had TH4. Going for the second Horn then never want to touch this NM again! Best of luck!
I killed this NM RDM+BST. RDM dot it and I used Audacious anna for infrasonics, Nursery Nazuna hitted hard, and Dipper yuly at the end of the fight. We used kitting metod around the lake. Very easy to kill. And drop 1/1
