[3.16][HC][ON BREAK] Caustic Arrow Raider, DoT Focused | Tanky | 6k+ Health | All Content | In-depth

If you're here, i assume that you have at least lvl ~73 and CA gem lvl 17. Cursed Frenzy setup and Wither Totem should be included in your build as well. If you don't have all of them, you might find single target damage disappointing. This build is dependant on levels, especially if you're starting the league. Don't rush the content.

Before you begin mapping, it's wise to pack as many CA gems to level as possible (if you didn't already). Once they hit lvl 20, you can corrupt them with Vaal orbs for a chance to get lvl 21 gem. You can have up to 12 gems levelling at same time, as CWDT setup isn't very useful until red maps.

White maps:
Passive Tree Progression (level 80) - rush Phase Acrobatics

They shouldn't be a problem at all. Most map mods are trivial, running them blue is completely viable. No real danger outside of few bosses like Pen, Grotto or Spider Lair. For this map tier, you have 3 very simple goals:

* 6-linked bow with +2 gems (ilvl 64+)
* Correct Flask setup
* Carcass Jack / Cherrubim's Maleficence (optional)

It's possible that you've acquired money for all of them before killing Kitava. If not, simple unid chaos recipe should do the trick. Body armours are optional boost to damage/clear. They're meant to help you early on, only to be replaced once you engage harder content.

Your primary goal right now is acquiring 6-linked bow, it's very simple. Buy ilvl 64+ 6-link bow, then spam alts/augs to roll +2 bow gems (prefix). You should get it within ~100 alts. The links on the bow should look like this:

CA - Vicious Projectiles - Void Manipulation - Swift Affliction - Damage on Full Life - Concentrated Effect

Keep in mind that you can use Efficacy instead of Concentrated Effect permanently, provides higher AoE for small price in damage. You also can always switch Swift Affliction with Greater Multiple Projectiles for map clearing. The AoE coverage is massive QoL in exchange for single target damage, which you can always solve by switching the gems again.

One of the things you should get are flasks with right mods. They're very important. Not having right flasks will heavily affect your survivability. 2 instant Divine Life Flasks with at least one having bleeding removal, Jade Flask with at least 90% increased evasion and Quicksilver Flask with curse immunity.

Yellow maps:
Passive Tree Progression (level 87)

This is where you'll spend quite a lot of time, recommended level is 80-90. This map tier isn't too risky, but some map mods might be deadly without proper defences/damage. Goals for this tier:

* +3 gems 6-linked bow
* Phasing path (uber Labyrinth)
* Level 21 CA gem
* 20% quality gems
* General gear upgrades

The +3 bow is the primary goal in yellow maps. You should craft it by yourself, as it's the cheapest way of acquiring one. Check crafting section for full details how to do it.

Once you have proper damage and defences, you can face Izaro inside uber Labyrinth. You will be safe as long as you dodge his attacks, which you should do with ease. Allocate remaining points in phasing path and ignore elemental ailments! Do not forget you need to have phasing/onslaught/maximum frenzy charges in order to gain the immunity.

Around the high tier yellow maps most of your gems will reach level 20. When that happens, the most important part is to vaal your maxed CA gems. Corrupting level 20 gem might increase it to 21, giving you significant damage boost.

Non-CA gems shouldn't be vaaled, quality is much more important on them. You can easily raise it with following vendor recipe (sell to shopkeeper):

Level 20 gem + 1 Gemcutter's Prism = Level 1 gem with 20% quality

It will lower your damage/defence for a short while, but within an hour or two there will be barely any difference at all with higher end game potential.

Do not forget about your other gear, it's equally important. Get more life and resistances, good jewels, CA helmet enchantment and all the other good stuff. Evasion gear is also important In short, upgrade it whenever you need, whenever you can.

Red maps:
Passive Tree Progression (level 93)

That's where mapping becomes tough. Monsters can hit hard, map bosses become tanky, map mods are huge pain. Your damage should carry you through most maps easily, but the bosses combined with some map mods can be too scary. The 5 following goals of this map tier will fix all these issues tier:

* Kintsugi
* Elder Ring with +4-5% chance to Evade Attacks (one required, two for additional safety)
* Malevolence aura
* Empower 3/4
* 7-link +3 Elder bow.

In that order. It's best to acquire Kintsugi as soon as possible. It's a cheap and underrated unique. Gives massive defensive boost for your character.

Despite very high evasion and Kintsugi on top of it, some maps might still give you a lot of troubles. Elder Ring should solve these problems. Paired with Jade Flask, Dread Banner and 25% more evasion from Onslaught path, it can reach up to 95% evade chance cap. You need ~70% chance on character sheet with Jade Flask up to be evade capped. Two rings are recommended, but one should be enough.

After you acquire Elder Ring/s, you will be able to switch aura from Grace to Malevolence without hurting your defensive capabilities... If you haven't switched earlier. However you can always stick with Grace for extra safety.

Once you upgrade your defences, the next upgrade should be Empower gem. Level 3 is easily enough for majority of the content. Level 4 would be ideal, but it costs massive amounts of money. Price is very high early on and drops over time. Empower replaces Damage on Full Life OR Concentrated Effect, your call.

Elder 7-link bow is a goal you probably won't reach. It increases damage output by ~15% more... for a price. It's not necessary to do all end game content, just makes it slightly easier. Once you get all other upgrades, optimize your gear and everything else - you can think about wasting money on crafting/buying one.

After that, all you can do now is enjoy the build, kill some end game bosses and look for another build you want to play.
