I got exactly this build on KOBT and my character is actually lvl 183
1- You’ll need 17~20 lvl 10 mana pots each dungeon to do something (Or use basic attacks and let your team carry you… so you’ll need only 8 mana pots)
2- Steady Aim is not as good as you think: Expensive mana cost, 15 seconds effect and 25 secs CD that will become 36 secs because you’ll wait for Spiral Arrow cd once its your best skill. The skill animation in each use will ■■■■ your positioning and your damage. 95% of fights you’ll lose 3~4 seconds to dodge boss spell with your miss positioning caused by Steady Aim’s animation.
3- Bounce Shot/Barrage >>>> Cross Fire: I got lvl 9 cross fire and its mana cost/after cast delay makes much better use Barrage/Bounce Shot with melee range. But this skill is still worthy if you use one time for burn status.
4- Spiral Arrow/Multishot > Barbed Arrow: With lvl 10 Barbed Arrow, the damage was almost the same, but use 2 Spiral Arrows and 2 Multishots uses less mana than 6~7 Barbed Arrows. Ground bosses are mostly Leather/Plate users and flying bosses that uses cloth are 85% ghosts, so Barbed Arrow’s potential goes down in dungeons. Another point here is the after cast delay of Fletcher’s skills, you can’t cast them moving like Heavy Shot/Oblique Shot/Critical Shot, so you’ll need to be really carefull when fighting bosses/great mobs.
5- You’ll use a good Bow or a nice Xbow with Arde Dagger, tons of SP potion to be usefull in party and while you run for your life dying in 1 boss spell, some QS will outdamage you with Ice Damage Shield and +3 Grand Cross attacking from far enough to avoid bosses’ skills.
I’m creating a QS now, may i’ll try QS 3 > Fletcher 3 with Broadhead/Magic Arrow for tons of DPS with 20s bleed/25 attacks, or maybe the popular QS 3 > Archer 3. I’m 49 right now, when I get 180~200 I tell you if it was effective.
