[3.9] [Updated] Caustic Arrow CI Trickster - Very tanky, fast mapper, safe playstyle



Welcome to my Caustic Arrow Trickster guide. So, after my Scourge Arrow  I decided to give a shot to another bow skill on new Trickster, and Caustic Arrow looked perfect, because I can fully abuse all defensive capabilities of this ascendancy. That is Ghost Shrouds and going ES and eva hybrid while getting insane recovery when something hits me, DoT on kill regen and recharge what basically keeps me always on full energy shield during mapping and also Soul Strike for very fast start of ES recharge. Trickster also has some huge DoT damage boost in ascendancy, what works really really well with CA. All this combined together results in probably the safest character I ever played with respectable single target damage and awesome clear speed.

Thanks to all points I mentioned above, this build is very viable for HC players, because we can fully focus on defense on our gear and in the end we can end up with  over 9k EHP with multiple layers of defense.

Pro's & Con's

+ Awesome clear speed - At higher levels our DoT "one shots" packs and with extra pierce and arrow nova we can cover whole screen with caustic clouds
+ Decent lab runner (because of our high movement speed, damage, self-regen from Ghost Shrouds and super fast ES recovery)
+ 269% increased movement speed
+ 9.7k Energy Shield
+ 1.03s delay to start ES recharge
+ Energy Shield recharge cannot be interrupted if it began recently (because of Wicked Ward)
+ 40k Evasion if hit recently, 20% less damage taken if not hit recently (thanks to Wind Dancer)
+ 93% melee avoid chance, 93% projectile avoid chance, 50% spell avoid chance, 9% reduced damage taken
+ 1600 ES gained per Ghost Shroud on hit
+ Stun immune (because of Ghost Shrouds)
+ Chaos immune (because of Chaos Innoculation)
+ Freeze and Chill immune (because of Dream Fragments)
+ Very safe playstyle. Because we are DoT build we can focus only on dodging and avoiding attacks
+ Can do any content in the game (except Hall of the Grandmasters because some characters there are CI) - That means no worries about ES recharge, leech, mana leech, regen, any kind of damage reflection
+ Only 6 link required is our bow (and it can be easily crafted)

- Single target is not that awesome. With optimized gear and gem swap we can get up to 2M effective DPS, what is pretty decent, but it can't really compete with meta builds
- For maximum damage and clear effectiveness we need either white socket on bow (for Concetrated Effect/Arrow Nova swap) or weapon swap with 2 setups
- We need plenty of strength from gear to meet gem stat requirements
- Min-maxing the build can be quite expensive, but the build itself is very flexible and do not requires a lot of investment to make it work

- All guardians
- All elderslayers
- Atziri
- Uber Atziri

Path of Building

Path of Building is tool for PoE to plan gear, skill tree and calculate effective damage. It also contains Bandits choice. You can download it here. Then simply import below Pastebin URL.

Pastebin

Navigating through PoB (important, read carefully)


There are 4 trees, for level 100, 90, 80 and 70. Use dropdown in bottom left corner of Tree section in PoB to cycle between them.

Tree contains workaround jewel for Wind Dancer keystone near Perfect Agony (we actually do not use perfect agony, it gets replaced by wind dancer). To get this keystone simply get Brutal Restraint jewel with modifier Denoted service of (500–8000) dekhara in the akhara of Deshret. Only the name (Deshret) is important.

There are 2 weapon skill gem sets:
  - Bossing: Here, we are using Concentrated Effect as 6th link for maximum damage
  - Mapping: Here, we are using Arrow Nova as 6th link to optimize our clear speed. Bossing/Mapping are basically gem swaps, swapping Concentrated Effect and Arrow Nova (requires white socket on bow, or what I personally prefer, weapon swap)


Pantheon

For major god Soul of Lunaris is good safety pick for mapping and some extra damage avoidance. Another great option is Soul of Solaris for extra safety on bosses.

For minor god Soul of Gruthkul is great choice for even more phys reduction (what we kind of lack in this build) and another slow.

Ascendancy

Get Patient Reaper first. Then get Ghost Dance and Escape Artist for some survivability and finally get Prolonged Pain from Uber Lab.

Leveling

As you can use Caustic Arrow from level 1, just use it the whole time. For smoother leveling try to get fast AS bow early and just craft some chaos damage to it. If you can, get Silverbranch and then Silverbought and just socket your Caustic arrow inside of it for some nice level boost, otherwise you can just use Tabula Rasa.

You can start with Caustic Arrow + Pierce Support + Onslaught Support links. Pierce is very important for CA because it creates additional clouds for each target pierced and Onslaught is decent for fast leveling

At lvl 4 socket Mirage Archer to your Caustic Arrow, then your leveling should feel pretty smooth.

Keep socketing supports that main build is using as soon as they are available.

At start just play as Life/ES hybrid. When you will reach at least 4k ES with ES gear you can start thinking about moving to CI.

Added new preview video of Lava Lake. I died once by accident (standing in DoT) but it was probably the smoothest t15 run I had with any character so early in progression (I am still just leveling the char). So here is the video (I also already added it to main post):

Here is updated PoB:

Another preview video:

As you can see, it was really simple and straightforward. As we do not need to care about reflect at all, there is not really anything that can kill us here.

As Synthesis is not going core and I want to keep this build future-proof, I removed Synthetized bow from guide and replaced it with +1 Vicious Projectiles multimodded bow. This loses us around 150k DPS, but it's fine.

Here is updated PoB (main thread is already updated too):

Added section about Toxic Rain as it can almost be played as drop-in replacement in this build, with better DPS but much worse clear. For more details check the Using Toxic Rain instead of Caustic Arrow section in main post I just added.

Updated the Toxic Rain section. I did some calculations, and with this build the actual Toxic Rain DPS is over 4.5M, what is pretty nice (that is with +1 quiver and +1 helmet enchant and Mirage Archer instead of conc effect).

I also added link to DPS calculator for Toxic Rain to main thread.

Added budget item set to the PoB that is not using Dying Sun, Solstice Vigil and +1 curse high rolled chest. Instead it is using Carcass Jack, Vixen's Entrapment and Bane to apply Temporal Chains.

You can see this new item set simply by switching to Budget in PoB in items section.
