[3.5 UPDATED 12/10 ] Sidefx Cthulhu Arrow (Caustic) Revived! - Occultist Variant VIDEOS

Sadly this guide had to be re-posted as the original one has not been touched since 3.1 and was then "archived" because of no activity. Enjoy

Hello, I'm Sidefxmayinclde
I wanted to play a DoT build but also wanted to be a special snowflake and not play ED/Contagion so I started to look at Caustic Arrow. While trying to figure out how to best scale the skill I also wanted something very safe to play as well. I really hope you guys enjoy!
This guide will be updated overtime with more information as I progress into the league.
UPDATE:1 The guide is now updated for 3.0 all passive trees and bandits have been updated.
UPDATE:2 For the most part 3.1 nothing has changed.
HUGE UPDATE:3 By far the biggest overhaul of this build - I have not updated it since 3.1, I know tons of people really enjoyed this build So let's bring it back! 3.5!

: Added Step by step leveling trees to try and help you have a easier time, Also added Gems and more info on the Ci version Tri curse. Lastly Also updated the PoB to contain all the tree's Just navigate to the bottom left drop down while look at the skill tree in PoB!

PoB Occultist LL CA
(also contains All lving tree's)


T15 clear with map mods not great for us (curse effectiveness ect) https://www.youtube.com/watch?v=PIHMptbVg6M

Trickster Version (will be updated soon as well!) https://www.pathofexile.com/forum/view-thread/1931405

This build focuses on damage over time mechanics in the game while also having AMAZING ES regen start time/speed
If you enjoy being able to rush into massive packs and kill them all without trying and not ever coming close to death then this is the build for you. This build farms Uber lab and all map tiers, no doubt in my mind that it would also farm shaper/elder. So im going to say now this build can clear all content but not without a decent wallet. There is are budget options below as well.

This build is Softcore and Hardcore Viable

Any questions please feel free to ask on my stream! Www.twitch.tv/Sidefxmayinclde or Click this image! please dont forget to FOLLOW to know when i go live!


Not that expensive to get going
Super relaxed play style
High content with low gear


Boring without MTX
Slower play style - sped up with 3.5 version
To min max will cost you a decent amount of currency
Crafting the god bow is tons of RNG

Bandits :

+2 Skill points

Required Unique/Current Items

We use this item because we dont take CI we reserve our HP so we need no chaos to get through!

The reason I have 2 here is because we weapon swap for clear/bossing you dont have too tho, you can gem swap

Gives us free despair without taking more of our mana also more DoT

Really good ES and 10% more damage + regen speed :)

This weapon in 3.5 got changed to 40% reduced damage (meaning over all) so this will hurt our clear(trash clear) but actually only slightly

Increased DoT!

My current items

How to craft the perfect bow (NOT CHEAP) This will be changing in 3.5 because of removal of master's but the craft idea should be the same

HUGE shout out to my boy https://www.twitch.tv/xxtremetvRIP :( for holding my hand while doing this go follow him as well!
Step 1: buy a white or yellow non corrupted 6l bow best base for CA is Steelwood or harbinger (about 20c)
Step 2: Slap a essence of delirium on it (pray that it rolls with only 2 Suffix (the 750 dot and 1 other best would be resistance) If it did not roll with only 2 suffix re delirium it (cannot have more then 2 suffix including the 750 dot)
Step 3: Take your bow to a Tora 8 and use the 2 ex craft SUFFIX Cannot be changed
Step 4: Scour the bow it will be left with only the suffixes
Step 5: Take your bow to Cata 8 and use the 1 ex craft Cannot roll attack mods
Step 6: Slam you will 100% get +1 to bow socket gems since that is the only non attack prefix when all 3 suffixes are now blocked Res or w.e you/the 750 delirium and now the Craft
Step 7: Remove the craft
Step 8: Take your bow to Leo 3 (pvp guy) and Craft 30% in creased damage over time (prefix)
Step 9: You should now have 1 open prefix and 1 suffix
Step 10 Optional: You could now double slam and PRAY for a +2 socketed bow skill gems (prefix) and another res in the open slots
