Quick Jump

Skill Tree

Ascendancy: Tailwind-> Fast and Deadly-> Far Short-> Ricochet

Bandits: Alira is worth like 4 points, take it on every crit build, especially this MF build.

Pantheon

Major: Soul of the Brine King

Brine King prevents stun locks which can often be the cause of death for squishier builds such as MF windripper.

Note: Make sure you pick up Nassar, Lion of the seas divine vessel for the 50% reduced effect of chill, this is important since we do not have chill immunity as a deadeye.

Minor God: Soul of Ralakesh (only if you have drek, apex hunter divine vessel) or Soul of Yugul

Note: If you plan on sometimes running elemental reflect maps without reflect immunity sextant you will need sybils + soul of yugul, attempt at your own risk. Soul of Ralakesh is nice due to reducing bleed issues not covered by the corrupting blood immunity, as well as granting us blind and maim immunity, nice!

Passive Tree

All the nodes should be pretty self-explanatory, abyss jewels are priority one due to how much flat elemental damage they give, prioritize flat lightning first, flat cold second, and flat fire third. Make sure you have enough cold to proc the 25% item quantity and lightning to proc the 50% item rarity from our windripper, fire is good for pure DPS purposes.

Gems Setup

6L Tornado Shot - General Clear

Tornado Shot-> Greater Multiple Projectiles-> Elemental Damage With Attacks-> Chain-> Mirage Archer-> Item Quantity

Our main skill, this will be used 99% of the time, with our incredible number of chain and fork projectiles a single shot can clear as much as 3 screens, with mirage archer we can fly through maps ridiculously quickly.

6L Barrage - Single Target

(This isn't 100% necessary but it gives your build the power to do any content, even uber elder!

Barrage-> Elemental Damage with Attacks-> Elemental Focus-> Damage on Full Life-> Slower Projectiles-> Lightning Penetration

Our bread and butter single target skill, can melt throw any boss with or without headhunter buffs, allowing us to clear maps safer and quicker.

Blink Arrow - Movement Enhancement

Blink Arrow-> Faster Projectiles-> Faster Attacks -> Enhance

Blink Arrow is invaluable in maps when we have obstacles in our way or are out low flasks, with faster proj and faster attacks blink arrow moves us extremely quickly.

If 4th socket available use enhance, I personally don't have room for enhance and that is totally fine!

Herald of Ice - DPS Buff & Charge Generator

Herald of Ice-> Curse on Hit-> Assassin's Mark-> Ice Bite OR Item Quantity

Assassins mark allows us to get another damage multiplier and provides us power charges. I personally use ice bite to generate frenzy charges, due to item quantity diminishing returns the occasional mod not having an extra 44% iiq makes less than a percent difference in loot, I would much rather than extra 14% DPS from frenzies

Cast when Damage Taken - Damage Mitigation

CWDT (Level 1!)-> Immortal Call (Level 1!)-> Increased Duration-> Vaal Haste (Levelled)

CWDT immortal call reduces physical spike damage a significant amount, this helps us survive any dangerous situations related to lots of physical damage hits. We also socket Vaal haste here to get the effect of increased duration, we do NOT run the haste aura! The vaal haste has no cast time, allowing us a free movement speed buff and attack speed to make mirage archer even smoother.

Wrath - Damage Amplification

Wrath (can link enlighten if you have room, but with legacy vinktars I have found that it is not necessary)

Wrath provides us with a lot of flat damage, the intelligence requirement is a pain but fortunately, vengeance collar solves that. Wrath paired with a multiple wrath mod watcher's eye means that for 50% of our mana we get around 30% more damage.

Gear

For a more detailed selection of gear, please refer to the PoB Link. The gear selected in the PoB is not mandatory if it is not stated. It is recommended that the player check the affix of the gear and make a better choice.

Required Gear

Legacy Windripper: Double Legacy is a huge power spike, but single legacy is fine until you can afford to upgrade. Implicit corruption is absolutely not required, so don't focus on that!

Rigwald's Quills: Rigwald's "projectiles fork" modifier is extremely useful for augmenting our clear speed to the point where we can clear entire screens with a single tornado shot. Implicit corruption here is EXTREMELY powerful but not necessary, but if you get any implicit corruption, I recommend this one. +1 Chain Rigwalds are not cheap, be prepared to spend a lot if you want to upgrade to one.

Queen of the Forest: QoTF gives us amount of MS which gets augmented further by our tailwind ascendancy node, making this chest incredibly strong. Bare minimum you need a single legacy QoTF, with double legacy being ideal. If you are trying to get a implicit corruption you may need to go with single legacy like I did just due to availability. As long as you can get around 33,750 evasion either legacy version works!

Vessel of Vinktar: This item is incredibly, incredibly overpowered and extremely important to the build. Vinktar grants us instant leech meaning that we almost never need to worry about mana, and are far more difficult to kill due to instantly healing to full health several times a second. It even provides a shock debuff to enemies around us and a lot of flat damage to boot. I do not recommend you attempt this build without a legacy vinktars. The flat damage ones are extremely expensive, start with a spells or penetration legacy vinktar if necessary, the main draw is the instant leech.

Headhunter: This may very well be the strongest unique item in the game, it gives us everything: Damage, movement speed, HP, resistances. Provided you get the associated buffs of course! This belt has a high degree of synergy with our build, our tailwind increases the potency of all our attack and movement speed head hunter buffs and that allows us to clear even faster, getting even more buffs!

You can play without headhunter in theory, but its really important for general mapping. For bossing I recommend a DPS stygian like: Stygian Vise

Important Note: Make sure you are resistance capped without flasks! Nullifier mobs or just running out of flask charges will be the death of you! I pick up some on the tree granting me the last notable for inspired learning, this may or may not work for you. Figure out what you want changes you want to make and sure you fill in that last little resistance if you are missing any.

Enchants

Helmets: The +2 sub projectile Tornado shot enchant is incredible. It is the equivalent to another support gem on our tornado shot. It is extremely important to the build, but not necessary to start out, get it asap.

Boots: I recommend either 16% APS/Cast speed if killed recently or 10% penetration if you haven't killed recently (Odd since they have opposite conditions).

The first enchant (APS) is extremely powerful since its essentially always up and makes our gameplay more smooth due to the additional attack speed, especially considering how mirage archer has an embedded 60% less attack speed modifier.

The second enchant (Pen) is good for bossing, I.E. Uber elder, this is very rare as I hardly find myself farming boss content enough to justify picking this enchant over APS. You should never have trouble with T16 bosses with this build, and therefore pen is not at all needed for general mapping.

Gloves: Honestly all the glove enchants are kind of irrelevant in the grand scheme of things, but "fury" is quite good in sometimes aiding mirage archer in clearing.
