Build Summary
Blood Surge Endgame Build
	Focus: DPS, Endgame Clear
Extremely Fast Farming Easy to Play High Durability, Sustain, and Movespeed Short Range

The build allows us to spam echoes of Blood Surges to nearby targets to quickly deal huge amounts of DPS and build up Overpower hits. Thanks to Soulrift's Essence Regeneration, we are able to spam our Blood Surge to an unlimited amount of number.

How Does It Work?

Despite being a Blood Build, this setup actually uses two main mechanics which are Overpower and Lucky Hits. We generate several corpses from Hewed Flesh and consume it instantly with Cruor's Embrace to generate insane amounts of damage while causing these corpses to spawn Blood Orbs to then allow us to spam Rathma's Vigor's effects.

Aside from Overpower procs, we also deal Decrepify to enemies which will reduce our cooldowns thanks to our high amounts of Lucky Hit chance which then lowers our cooldown for our abilities which can be used for Soulrift which again, generates Essence for the build's main resource generation.

Blood Surge Build Book of the Dead

Skeleton Warriors	Skeleton Mages	Golem
Defenders Sacrifice	Bone Sacrifice	Iron Sacrifice

For this build, we'll be maximizing our Resistances, Overpower, and Critical Strike Damage by sacrificing Warrior Skirmishers, Bone Mages, and Iron Golem. This will allow us to capitalize on our Overpower and Critical Strike damage bursts.

Despite the Defender - Sacrifice choice which may seem out of place, Sacrificing Defenders will allow us to hit our Resistance caps without investing too much on our items. This will allow us to focus our items on other effects that will push our damage capabilities further!

Blood Surge Build Gems

Armor	Weapons	Jewelry
Topaz	Ruby	Skull

Topaz and Rubies are the best gems to slot in to further ramp up our dps thanks to the Topaz's intelligence bonus and ruby's overpower proc.

We slot in Skull to fill in our missing armor values as our book of the dead will already fill up the resistances. However, feel free to change this depending on the stat values your build currently has.

Blood Surge Build Runewords

Runeword 1	Runeword 2
Tam Jah	Bac Gar

Tam and Jah amplifies the build's mobility further by granting us a free Sorcerer Teleport everytime we use Blood Surge 16 times. Despite being a high number, we'll be spamming Blood Surge non-stop which makes this extremely easy to proc. Use Blood Surge and walk to the nearest camp then if the next enemy batch is in a distance, teleport using dodge to repeat the cycle.

Bac Gar is the next one and this aims to alleviate the sluggish nature of the Necromancer by allowing us to gain Movement Speed by moving which essentially means that we get a ramping movement speed to allow our Necro to quickly pick up Blood Orbs as well as traverse the area while exploring.

Mercenary	Reinforcement
Raheir	Varyana

The best mercenary for the Blood Surge Build is Raheir, who gives 5% Fortify (buffing your Overpower damage) with Shield Charge, boosts your Armor by 15% with Raheir's Guard, and grants Damage Reduction and increases damage to enemies with Provoke and Mocking Lure.

For the Reinforcement, Varyana is the best pick as she can use Bloodthirst to boost your Attack Speed by 10%.

Paragon Boards
1. Starting Board (Control)
2. Blood Bath (Corporeal)
3. Flesh Eater (Dominate)
4. Blood Begets Blood (Essence)
5. Frailty (Sacrificial)

This is our main paragon board setup that shows the priority of nodes we want to tackle for our boards. Mainly, we'll want to prioritize getting Maximum Life, Resistances, and Damage. For damage boards, we'll want to focus on Overpower as this is where the majority of our bursts come from and we'll also want other damage modifiers such as damage to elites as well as flat out damage multipliers.

In the guide of Ruse_Cruize himself, the build's gameplay loop is as follows.

1. Use Soulrift.
2. Use Blood Surge.

This is as simple as it gets as you can pretty much play the build with one hand if you're willing to rebind your keys a bit as you'll only be using Blood Surge, Soul Rift, and evade for this build.
