Strong and fun solo build based on high damages in all situations, and reliable regeneration of health.

Vampire stage : 1
Buff food : Artaeum Takeaway Broth (or Dubious Camoran Throne)
Main bar poison receipts : Blessed thistle, Stinkhorn, Corn flower/Emetic russula/Nirnroot/Nightshade/Violet coprinus
Potions : Standard Physical power pots (Blessed thistle, Dragonthorn, Wormwood/Water hyacinth)

Pros :
- Very high penetration with sets bonus, minor breach from the spam, and major breach from Reaper's mark
- Excellent sustain with use of pots
- Lots of possibilities of healing (from all damages, on kill, Spectral bow, and by turning off Frenzy for a ressource-free heal)
- Good mobility with Hasty retreat bow's passive
- Strong use of Strategic Reserve, as the vamp' heath regen malus is compensated by Refreshing Shadow passive, and refills fast with Soul harvest, Catalyst, and Transfer
- Panic vamp ultimate for almost invincilibity, tought moments, and for burst phases
- Melee/range combo
-Bit of extra health with Trainee's 1 piece (light)

Cons :
- Squishier than most builds with reliable Major resolve
- More sensible to crowd control (risks to get bursted)
- Weaker with low ultimate number
- Lower penetration for multi-target
- Set's stacks to mantain

How to use :
- Reaper's mark can be applied during the spammable's travel time, it's can be abused on low-health targets for a fast insta-heal and Major Berserk.
- Sated Fury isn't only a damage skill, it's also a healing skill : it's boosting Pale Order's heal, and can fully heal you when turned off for free if mantained long enouth.
- Keep the Relentless focus shot for heal or burst damage with the spam travel time.
- Try to not use heavy atks if you aren't maxed charged with Yandir's might, or you'll be stuck 15s with lower damage buff from the set.
- To keep safely Tzovgin max stacked with bar swap, do not use more than 2 skills in a row on your back bar.
- Acid spray actually does more damages on it's initial damages + full duration DoT than the spam and help keeping set's charges with his multiples damages ticks. If you're good with sustain, you can use it as a DoT.
