Revolves around getting behind your target to do extra damage, your target takes 10% extra dmg while kidney shotted, and you have +20% dmg when using backstab from behind. Your passive increases your damage by 20% while behind targets.
This is a more self sustain promotion class, you will have lifeleech, self-barrier when stunning enemies and reduced cooldown on kidney shot and Backstab. Your passive gives your Nature and Poison toxins 8% lifesteal.
This is the more CC/DoT heavy build, your kidney shot applies a severe bleed, you get the power cheap shot (stun from stealth), and your backstab supresses enemies if you hit it from behind. Your passive will save your ass (the hit that would have killed you, instead takes you to 15% max health and gives you 90% mitigation for 4 seconds)
