[3.1] The Azure Knight Raider (Flurry/F. Blades/Life/Crit/Conversion) (4 min Shaper run)

Let me say this first: I don't have a Raider character in Legacy or even Standard. This build was first theorycrafted for the Occultist, but can be very easily converted to majority if not all classes in the game.
Here is a link to the main page of the build: https://www.pathofexile.com/forum/view-thread/1898845

In the link above, you can find more information about how it works, why certain gear was chosen, alternative gear setups, Frost Blades setup, extra videos, and more.
Even as main page of the build was written with Occultist in mind, 99% of information there applies to Raider as well.

If it is a general question, you might find an anwser in the main build thread, but always ask here if you want Ranger specific advise.

3.1 Raider version:
Shaper run. Performed by Phertux.

3.0 Pathfinder version:
Shaper run. Performed by Hejtero.
Minotaur kill. Performed by Hejtero.

3.0 Raider version:

Shaper run. Performed by Phertux.

2.6 Occultist version:
Shaper run.
Hydra run.
Chimera run.
Minotaur run.
Uber Atziri run.
Chayula run.

Ascendancy:
Core lab points:
- Way of the Poacher: Constant Frenzy charge generation, Frenzy charges are OP.
- Avatar of the Slaughter: Additional Frenzy charge, and more quality to your charges.

Dps version (approx. 15% more dps then alternate version and much higher Evade chance):
- Rapid Assault: Free Onslaught buff for mapping, and against bosses with adds.
- Avatar of the Chase: Massive evasion bonus if you have Onslaught, and double the Onslaught buff. Great dps, speed clear, and defensive node.

Alternate version (36% dodge and 40% spell dodge + elemental status immunity):
- Quartz Infusion: Additional Dodge chance and free MTX effect.
- Avatar of the Veil: Spell dodge, increased damage and elemental status immunity, which includes Shock and Burning, which can make a big difference between living and dying on maps with these effects (mainly Shock).

Example tree level 88
Flask nodes are taken primarily for the mana regeneration, as otherwise movement with Whirlwind Blades might not be sustainable. If you get mana regeneration on your gear, you can potentially drop Primveal Spirit and go for more dps - Fencing is a very good notable with plenty of Crit chance, for example, there's also Heartseeker.
As a Raider, your advantage is super fast movement speed - if your regen isn't good enough, it will just slow you down.

In 3.0, picking Alira reward with flask nodes should be enough to cover your mana needs. If your gear is top tier (easily capped resists), you can take 2 points instead of Alira reward.

There is already an in-depth quide on gear and gem progression in the main Witch thread, which applies to this version as well - don't forget to check it out!

Example tree, 38 points.
This is when you will get your Blade Flurry gem and other supports. You might want to skip Winter Spirit if you don't have the gloves, or you can use Physical to Lightning support, take Winter Spirit earlier and use appropriate gems like Elemental Damage with Attacks.
Filling out top part of the tree is a priority at this point, no need to go into Duelist area for now.

Example tree, 73 points.
Get Claws of Magpie and work your way towards Assassination first. From there, the leveling tree is easy, as you just go down towards Duelist area and later get Constitution, before filling up other nodes. You can also take Twin Terrors and Thick Skin before heading down to Master of the Arena and Constitution, like in the link above.

Major:
- Soul of Lunaris is a great pick, synergizes very good with our defenses. Best mapping choice imo, also increases your spell dodge chance to 35% with Perfect Form, and gives you a chance to avoid projectiles.
- Soul of Solaris is also decent, but not as good as Lunaris, even if Solaris bonus can be better in some rare cases.

Minor:
- Gruthkul is great, as being close ranged character we are getting hit constantly. Additional slow also helps with survivability.
- Finally, Yugul helps us deal with reflect, if this is your main concern. Take it especially if you are playing Frost Blades version.

Ignore the gem links, as gear is taken from my Witch version of this build.

Abyssus best dps increase from any non-weapon gear slot, at the cost of survivability.

Starkonja is a lower dps, high survivability option, probably more popular nowadays with 3.0 Abyssus nerfs.

The Perfect Form gives us free 30% spell dodge chance, free Arctic Armour and Evasion matching that of other top tier Unique armours. A corrupted rare 6 link might be better due to a price, until you can afford your own 5-6L Perfect Form.

You could use Belly of the Beast if you don't like relying on rng defenses, you'll lose AA and spell dodge but gain roughly 400 life and resistances.
Carcass Jack is also a good dps/clearspeed choice, same cons as Belly.
(Note: with these 2 options, you can use Damage on Full Life instead of Cold Penetration or Bloodlust support with your totem linked to Chance to Bleed. Is it less practical, since Damage on Full life means no Blood Rage and slower clearspeed, and Bloodlust is a bit clunky against bosses.
However, you will be able to reach higher values in Path of Building, if that is your thing.)

Rare boots/belt should come with a lot of life and resists on them. Movement speed is unnecessary, it's more of a QoL.

Hrimburn/Hrimsorrow convert the remainder of our damage into cold.

Rare rings/amulet follow the same pattern as boots/belt - you want life and resists. If you can squeeze any offensive stats, accuracy/physical damage/crit multiplier are great to have.

Doryani's Catalyst is BiS offhand, greatly increasing your dps, however that is not included in your tooltip. Other, cheaper offhands include Doon Cuebiyari and Singularity.

Rare claw/Touch of Anquish/Wasp Nest are also BiS for this build. Even though ToA has only around 270 dps, it beats most rare claws with 300 dps or even higher, thanks to cold damage increase and high critical strike chance. Wasp Nest also provides 95% dps of ToA for 5% of the price, so it is superior choice until Frost Blades meta dies off.

Please check in the main Witch thread for all flask and jewel breakdown.

Attack:
Blade Flurry / Melee Physical Damage / Weapon Elemental Damage / Elemental Focus / Increased AoE or Concentrated Effect / Cold Penetration

Auras:
Hatred
Blasphemy+Elemental Weakness (unless you have gloves corruption, then use Herald of Ash for more dps)
Arctic Armour

Utility:
Cast when Damage Taken / Ice Golem / Blind / Ancestral Warchief
- recasts your golem so you don't have to, allows your golem and totem to blind enemies - massive evasion boost for Raider.

Buffs:
Enduring Cry / Blood Rage / Vaal Lightning Trap
- EC helps mitigate increased damage taken from Abyssus.
- Blood Rage increases dps and leech.
- Lightning Trap increases dps against bosses that can be shocked. I usually forget about its existance - make sure you don't. You can also use Vaal Haste if you prefer.

Debuffs:
Cast when Damage Taken / Frost Bomb / Vortex / Inc. AoE
- chills nearby enemies and applies -20% cold resistance debuff.
You can also use Immortal Call instead of Inc. AoE gem for added survivability.

Movement:
Whirling Blades / Faster Attacks / Fortify

Over 5.03 million dps using a 320 dps claw.
Over 4.14 million dps using Touch of Anquish.
Over 3.29 million dps using a 320 dps claw against bosses
Over 2.71 million dps using Touch of Anquish against bosses

Over 6k hp at level 90.
11k Evasion buffed.

Occultist can run 2 curses at the same time, Elemental Weakness and Enfeeble. Enfeeble is Occultist's own flavour of Raider's evasion bonus - as a Raider, we can get more % evasion, especially against Blinded enemies, but any hits that connect hurt us more.
Also, we need to kill in order to trigger our Evasion bonus, which isn't going to happen in some boss fights. However, when you do kill (mapping) or against bosses with adds/trash monsters, your higher Evasion will grant you same or higher survivability.

Raider can reach much higher dps values then the Occultist, especially if you prebuff with Power Charges, and movement speed is also a lot higher thanks to perma Onslaught when mapping.
