Breeze Arrow [20]
Wind Walk [15]
Element: Storm [10]
Whisper of the Wind [20]

More speed and mobility is probably the best thing to get. Whisper of the Wind should provide the most damage boost, and let you hit things higher level than you I guess. Breeze Arrow next, but only to 19.

Then Storm is maxed for damage.

tl;dr:

1. Max Wind Walk
   
2. Max Whisper of the Wind
   
3. 19 Breeze Arrow
   
4. Max Element: Storm
   

Fairy Turn [20]
Gust Shot [20]
Trifling Whim I [20]
Sylph's Aid [10]
Bow Booster [10]
Bow Mastery [10]
Physical Training [5]


Fairy Turn is your primary training skill. Gust Shot rarely ever has a use. It can't hit as high or low, and has barely more range, and it's not noticeable in most cases. Some early booster will let you

OHKO faster. Sylph's Aid gives 20 watk for 10 points, and some critical rate. It also removes arrow costs. Physical Training's DEX bonus and Bow Mastery's bonuses should provide the most damage next.

Trifling Whim I can have it activate on occassion and OHKO nearby monsters.

tl;dr:

1. 1 Fairy Turn, Gust Shot, Trifling Whim I
   
2. 5 Bow Mastery
   
3. 5 Bow Booster
   
4. Max Sylph's Aid
   
5. Max Physical Training
   
6. Max Bow Mastery
   
7. Max Trifling Whim I
   
8. Max Bow Booster
   
9. Max Fairy Turn
   
10. 19 Gust Shot
    

Dance of Frozen Wind [20]
Pinpoint Pierce [20]
Trifling Whim II [20]
Albatross [20]
Emerald Flower [10]
Feathery Knees [20]
Second Wind [20]

One point in Feathery Knees reduces damage taken by 5%, and one point in Second Wind boosts avoid by 11%. Primary training skill will be Dance of Frozen Wind unless you Monster Park, PQ, or OHKO really well

with Fairy Turn. Albatross provides the most DPS first.
Max Dance of Frozen Wind is next for more damage if you train with it. If you don't use Dance of Frozen Wind to train, or you want to conserve MP, or take less damage, leave it until later. Feathery Knees

is next to reduce damage taken. When you're training with Dance of Frozen Wind, the only real damage you might take is when you're moving around and it's rare, so Second Wind won't activate as much;

however, Trifling Whim never activates with Dance of Frozen Wind. Emerald Flower is also useless when training with Dance of Frozen Wind since you can just stand on a platform.
If you're training with Fairy Turn, Trifling Whim is after Albatross, then Feathery Knees and Second Wind since they're used often in this case. In most cases, where you're using Fairy Turn, it will be PQs

or Monster Park, where monsters aren't being OHKOed to make use of the DPS, so Emerald Flower can come in handy.

I constantly had the issue of outranging monsters with magic attacks when I was not on a different platform using Dance of Frozen Wind. Fairy Turn's attack range is short compared to other archer classes,

but it is probably the strongest skill before 4th job of any of those classes as well. Pinpoint Pierce is seemingly useless. Fairy Turn is the superior skill for DPS in all utility except range.
tl;dr:

Cygnus Knight [30]
Sky Song [30]
Spiral Vortex [30]
Trifling Whim III [20]
Wind Blessing [30]
Sharp Eyes [30]
Bow Expert [30]
Emerald Dust [10]
Albatross Maximum [30]


Spiral Vortex is the primary training and bossing skill for a long time. Sky Song is only better for single target when you have Storm Bringer at 150 I believe. Spiral Vortex will always be better if it can

hit two targets. Albatross Maximum, Bow Expert, Sharp Eyes, and Wind Blessing should provide the most damage in that order.
If you want to boss at something like Zakum or Horntail, I would recommend placing Sky Song, Trifling Whim III, and Emerald Dust before Wind Blessing, as I doubt Spiral Vortex can hit many arms at once.

Spiral Vortex appears to have the vertical range of Iron Arrow, but the splash hits rather high and low, so if you can hit arms, they'll splash each other. I doubt you could splash Horntail's heads though

since the splash horizontal range is poor.
Otherwise, in the case of training at Monster Park, or in GMS at LHC, Spiral Vortex will be vastly superior. Trifling Whim has a very small effect on Spiral Vortex, especially compared to Sky Song, and gets

even lower the more targets are hit.
tl;dr:

1. 1 Spiral Vortex, 1 Sky Song, 1 Albatross Maximum, 1 Bow Expert, 1 Emerald Dust
   
2. Max Spiral Vortex
   
3. Max Albatross Maximum
   
4. Max Bow Expert
   
5. Max Sharp Eyes
   
6. Max Wind Blessing
   
7. Max Emerald Dust
   
8. Max Sky Song
   
9. Max Trifling Whim III
   
10. Max Cygnus Knight
    

Trifling Whim - Reinforce [143]
Trifling Whim - Enhanced [162]
Trifling Whim - Bonus Chance [183]
Spiral Vortex - Reinforce [149]
Spiral Vortex - Extra Target [168]
Spiral Vortex - Bonus Attack [189]
Sky Song - Reinforce [155]
Sky Song - Ignore Guard [177]
Sky Song - Boss Killer [195]
Storm Bringer [150]
Monsoon [170]
Glory of Guardians [200]

For Sky Song (i.e. single target), all the Trifling Whim Hypers, and Sky Song - Reinforce and Boss Killer provide the most damage.
For Spiral Vortex, replace Trifling Whim - Reinforce with Spiral Vortex - Reinforce.
