Bar1
Silver Leash – Deals *** of damage against Vampire and non Vampires.
Dragon Fire Scale – Reflects almost everything. Use it wisely, you dont have much Magicka.
Molten Armaments – This buff has to be up as much as possible because it boosts your Heavy Attacks by 40% and if enemies have lower HP then even higher
Scatter Shot/Magnum Shot/Bombard – Kocks enemy away from you. However, I usually prefer Scatter Shot(unmorphed skill) because you do not get knocked back yourself. Bombard can be used to root enemies to the ground if you fight multiple enemies.
Camo Hunter – Try to keep this buff up as much as possible, crazy extra damage if it procs, especially against Vampires

Ulti: Flawless Dawnbreaker – Mainly here to provide some extra Weapon Damage. Very Nice damage against Vampires.
Bar 2
Rally – Our main heal ability, keep this buff up 100% of the time.
FREE SLOT/Camo Hunter/Choking Talons/Speedbuff/Vigor – Put whatever you think suits you the best

Executioner – After you use Take Flight Ulti immediately use this skill to in most cases instakill your enemy.
Wrecking Blow – If you are forced into close combat this is your main damage skill high damage output, be careful tho, it has a 1s cast time.
Structured Entropy – Before you activate Take Flight Ulti you use this one to give your Ulti the 20% Increased Damage Empower buff.
Ulti: Take Flight – Huge Range and crazy damage, my tooltip is at 20k atm approx.
I have only replaced in 2H:
structured enthropy with petrify ,bar2 - second slot I have expert hunter
and
in bow:
dragon fire scales replaced for green dragon blood
silver leash replaced with rapid maneuver
I have 1 heavy, 1 light, 5 medium
5 hunding`s range set
2 nightmother`s gaze set
This build`s burst damage is done by animation cancelling (check out the video above), I still can not do it, but for PVE this build is great. with animation cancelling, it will be also awesome for PVP.
