Emphasis on the battle part k, as you can see ;D
Quite frankly, the only good heals for actual healing are LoH and rBeads, in my mind. So... time to pack up as much dps as possible! xD
Before anyone says "wth why max moon fog instead of pieces", its CD gets lowered to 25 in the future. This makes it Eir's strongest dps skill by far, considering its AOE. 4 hits of 320~360+Str Enhancement, along with 25% slow, every 25 seconds, kicks ass for an Eir skill.
I didn't max Moon Pieces because by the looks of the skill builder, the heavy boost we got to Moon Pieces damage gets removed (aww). So, Eir's other skills are still, in general, better dps. Seriously, Moon Pieces fails completely against a mob of monsters, and isn't that great against non-knockbackables. Even Holy Spirit is better considering against those. It gets x3 hits instead of x4, on even tiny targets, for slightly better dmg then moon pieces each hit;plus, its a linear AOE, so that rocks.
 LOL forgot to post the build *inserts*
THIS IS WHY I'M CALLED FAILSERELA
