Possible archer hero spoiled?

Transforms bow into harp and makes beautiful music to buff up allies and attack enemies.

I'd prefer something along the lines of still an archer, but weaker...

HOWEVER, gets stronger with a party, providing buffs, AND something like a special skill where you can borrow self buffs from other classes. Like, if you are near a NL that uses Shadow partner, you get the buff too, or transformation, but with a bow, etc.

Tweak it out a bit, and you get an interesting class.
