3.17 TOXIC RAIN CHAMPION - Fast, Tanky, Deadly! - League-Start to End-Game

Pro's
- TANKY! This built can face-tank most content in the game.
- FAST! Movespeed is fantastic... +200% when all things active!
- DEADLY! T16's just MELT, Deathless Sirus A9, Maven, Formed, Twisted, Feared.
- ALL CONTENT, ALL MODS! A true "Alch and go"... can do all map mods.

Con's
- Lots of balancing of gear - resistances, strength, intelligence, life, DOT, mana reduction)... but most builds have this challenge.
- Can be expensive to min-max.
- It's not Tornado Shot.

Note that this gear can be interchangable with other stuff... see detailed gear section further below.

Bow:
Crafted with extra DOT or Attack Speed. Quill rain can be used early game.


Quiver:
DPS quiver with life/res stats, or Maloney's for frenzy charges, culling strike, or vaal haste, or other combo of your choice. I personally enjoy run with Maloney's because I use QOTF chest (no frenzy generation).


For Maloney's, I usually run with Caustic Arrow + Awakened Arrow Nova Support + Frenzy

A couple of other great options are:

Caustic Arrow + Awakened Arrow Nova Support + Chain
Caustic Arrow + Culling Strike + Frenzy
Caustic Arrow + Awakened Arrow Nova Support + Vaal Haste
Frenzy + Culling Strike + Vaal Haste

It all depends on your preference of playstyle.

I swap in Culling Strike for bosses.

Chest:
QOTF for speed, or armour with great stats (life/res), or armour with frenzy on hit, or armour with additional curse and you can run frenzy + curse setup (eg Poachers Mark) in Maloney's quiver.


Helmet:
Devouring Diadem means we can spam our skills without mana issues, and no need for a mana flask (yay). It provides great QOL for the build.

Otherwise a -9% chaos pen helm for DPS, or Viridi's Veil for more defence.


Gloves:
Chaos DOT and craft increased AOE. Or some gloves with DOT and Culling strike/attack speed. Null and Void gloves add a lot of fun if you want to spice things up.


Boots:
Boots will spell suppression to ensure we cap at 100%. Other stats of your choosing.


Amulet:
Chaos DOT, +1 dex or chaos gems, other stats of choosing. Corruption annoint.


Rings:
Life/res. One ring with Curse enemies with despair on hit.


Belt:
Life/res or other stats you need. Headhunter if you want or mageblood.

Now I see some comments here and there regarding some aspects of toxic rain as a build in general, and I do agree that it will take some extra investment to cover some relatively important layers.

For example, if you are just running like a level 10 Vitality and popping blood rage, you are basically going to struggle with gettign your HP back once you run out of flasks.
Scaling your life regen higher is one way to help with this, but another very strong layer of life recovery is using a Life on Hit while affected by Vitality watchers eye, or a rare ring with 20 life on hit mod.
I would also HIGHLY recommend using a enduring cry. It's really nice way to gain some hp on demand. 2k hp over 1 second + endurance charges.

Another thing people seem to struggle with is mana problems.

There are a few ways to approach helping with that...

You can craft on rings -7 and ammy, and you can increase this to -8 with life mana catalysts.
If you manage to get a ring that was unveiled, it goes up to -10 which can be upgraded to -12 mana cost with catalyst.

You can also get rare jewels with 5% reduced mana cost mod. So if you find a jewel with like %life, mana reduced costs and other damage mods, that's a solid alternative to help lower your mana cost up to zero.

If you are having trouble against damage over time, you could consider investing in ways to prevent that.

Elemental Ailment immunity is possible.(ignite damage) You can get up to 45ish % on boots. You can craft it on certain armor slots. You can get passives on the tree and so on.

Poison, you could use the Soul of Shakari pantheon, which i do sometimes depending on the content im running. I personally use soul of Arakali for Major Pantheon, it really does help.

For bleed and corrupting blood, you could get a corrupted blood immunity jewel. Highly recommend.

The cheap, temporary alternative to some of these ideas, is to just have flasks help with this...
