Not a bad build.However, I recommend you switch over to a str build since for me it's easier to level like that. I just pop a super knowledge, heroic haste, heroic travel, and heroic health and I get about 2.5 bars - 3 and I'm 116.
So basically for stats:
Str: 300
Dex: Rest
Foc: None
Vit: 300
This is pretty good for bossfights also considering you need health to stay alive.
For skills:
Sharpen Weapons: Max
Steady Aim: Max
Double Shot: Max
Rapid: Leave at 1
Bolas/Camo: Rest if possible
My sharpen weapons adds about 71 dmg and my steady aim adds around 30 even though I only have 200 dex.
If you want to level faster, try camping the lvl 190 fairies and ask high levels to help you. When it's almost dead pop an exp lix and you'll get around 3-4 bars.
Seems like too much health to me that you could be putting into str or dext because you are on a heroic regen lix... Id look into that and do you use restos? I hardly find myself having to heal!
I believe that 300 vit is a fair amount to me. After all, when leveling on the golems or bolgs, they hit pretty hard and I don't wanna be finished in like 4 or 5 hits.
As for restos, I don't use them, but I keep them on the side just in case if I'm going against a fairly strong mob.
Also, for your I can clearly see that you are loaded on lux. You have aggy bracelets which for me is pretty hard to obtain considering that I need DKP points and buying them would be out of the question since they are expensive and etc.
For your skills, what is your skill set?
Did you max the skills I told you to max?
