Level 90 Explosive Arrow Raider^3.21

Notes

Start with Galvanic Arrow , Rain of arrows and then explosive arrow. First buy, always quill rain, as soon as you can afford it ( ranges from 1 alch to 2 chaos on league start)
NO PIERCE, NO CHAIN, NO FORK, NO ADDED FLAT DAMAGE ( % is fine, just not something that says 4- 12 fire damage to attacks, until you remove elemental equilibrium) 


Level assasin mark, but since you cant deal criticals with precise technique, you can choose another mark to use as your default, like warlords for endurance charges or poacher.
Also you can look at a setup with frenzy/snaring arrows , the new support gem manaforged arrows, flammability and hextouch.
Level in your off hand explosive arrows , so you can corrupt them at lvl 20, with no quality to try to get one lvl 21.
depending on price the new tanu ahi gloves will be beatifull here, as you can have a very high uptime on adrenaline with them. If you get them, you can drop the leech nodes. You can also drop those if you use lifetap
As for gear, basically you can just do wathever you need to fill your stats, stats, life, resistances are all good. Boots with movement speed. Try to get the rest of your ailment immunity chest craft ( 25% ) and another 10% from the tree, near avatar of the hunt.
The poised prism is a good quiver once you drop your elemental equilibrium after uber lab.
I added a lot of uniques and items that can be great if you can obtain them.
Eventually you want to transition to crit, but you will actually need good gear for this. 
More options, you can double down on haste with sublime vision and Herald of ash as your only auras, you will be literally flying, but you will be a glasscannon, and will depend a lot on how fast can you dodge and move to avoid damage.
On the other side, if you get devouring diadem, you can have haste, grace and determination runing, to make yourself semi tanky.
At some point you want to start working on getting a corrupted chest with +2 to ( aoe. projectiles, duration gems) or a +1 to all if you also have empower. In the best case scenario you can get a +4 chest but those are usually expensive on good unique bases.
Unnatural instict is really good in the area next to avatar of the hunt and will save you points.
Clusters are really good. Moving to deadeye is good if you want to use far shot + endless munitions + focal point + gathering winds. This is the only way you can go crit on the build, since you will be using assasin mark with a lot of increased effect.
