Level 97 Doom Blast Pathfinder^3.21

Notes

!!! WARNING !!!
I DO NOT RECOMMEND SWAPPING TO IMPENDING DOOM UNLESS YOU HAVE ALL THE GEAR IN PLACE!

It is best that you acquire these critical pieces first: 6L staff, lightning coil, vixen's, annoint, taste of hate & other flasks.
These items rely upon eachother to create a minimum viable build; additional explainations below.

I recommend following Zizaran's Toxic Rain Pathfinder before respeccing to Doom Blast once you have aqquired the gear.

ITEM BUILD

Flasks:

! IMPORTANT !

As a pathfinder, the flasks are used to cap resistances. Acquire TASTE OF HATE asap! -- Incoming phys taken as elemental is an important defense layer.
Craft '% reduced Mana Cost of Skills during Effect' onto flasks asap! (You can exchange whetstones into glassblowers via vendor early on)
Automate flask usage with instilling orbs. Prior, res cap using gear.

Due to lack of life leech, use a life flask to combat ground based dots. The build has elemental ailment immunity, bleed negation via pantheon, however recovery is VERY important!
Once you have an alternate quality Void Manipulation, you can switch the life flask for a quartz flask. The life leech should provide more than enough recovery.

Weapon:
#1) Get a 6 LINK STAFF ASAP!
Early, corrupted 6L staves are cheap due to lack of demand; this makes acquistion cheap & easy. Look for at least 1 good damage mod on the staff.

#2) UNCORRUPTED 6 LINK STAFF
After amassing some currency, try to purchase an uncorrupted staff.
There is a divination card "The Dark Mage", a set can be exchanged for a normal, item level 55, 6-link staff. 
This card drops in Overgrown Ruin and Overgrown Shrine as well as Act 7/Chamber of Sins Lv.2 (not recommended); farming is similar to porcupine cards. The card can be purchased for cheap as they have low demand.
Once acquired, alternation spam for chaos damage over time multipler (t3 is max) and craft +2 to socketed support gems. (This benchcraft is available after unveiling the mod on a Catarina rare item; costs 2 exalted orbs) 
Alternatively, +1 to support gems craft costs 8 chaos. This card set is a good way to get your first staff. 


Helmet:
#1) A strong helmet base with life and suppression. If possible, chaos resistance.
Chaos resistance is more important in this patch due to incoming new map mods: "Enemies have #% of physical damage as extra chaos damage" & "Enemies inflict withered"
If you manage to cap your resistances and your suppression and you still have an open affix on your helmet, consider crafting on "ailment duration while focused" for more damage, or "physical damage taken as fire" for physical damage mitigation.


Body Armor:
#1) Source a betrayal chest with gravicious mod for physical damage taken as elemental.  It is imperative that you get a lightning coil ASAP! The build does not have any sources of physical damage mitigations besides guard skill, lightning coil and flask.

#2) NOTE: Lightning Coil has NEGATIVE Lightning resistance (-60%). Cap resistances accordingly prior to equipping Lightning Coil.


Gloves:
#1) Vixen's Entrapment
This is core item. Purchase as soon as possible! The build will NOT function without these gloves, so do not attempt it without them.

NOTE:
The vixen's proc cases curses clockwise, starting with top-left. The first curse, socketed in top-left, is always overriden. Here, punishment is recommended. Socket spell-cascade, enfeeble and temp-chains in the other sockets; order is not important.


Boots:
#1) Priorize spell supression, resistances and life.
Movement speed is an early luxury mod.


Amulet:
#1) IMPORTANT! Skittering Runes annoint is mandatory!
The annoint fixes mana cost issues; un-annointed, the build is unable to cast. The curse spam is highly mana intensive.
This annoint is expensive, as an alternative, consider running inspiration in the 6Link instead of Deadly Ailments.
As the guide recommends acquiring a 6L asap, without this annoint, it effectively becomes an expensive 5L, however, since inspiration only increases elemental damage, you lose a large portion of your damage, so I do not recommend this route.

#2) Source missing attributes here.

#3) Make sure to benchcraft craft -mana cost as a prefix. This craft is an "Elreon Jewellery" veiled modifier, and can be aqquired by 

Rings:
#1) Use rings to acquire missing resistances and attributes


Belt:
#1) Acquire CDR benchcraft.
Flask duration is QoL for 100% uptime on quicksilver.


Jewels:
Large Clusters - source lategame when highly leveled to properly allocate nodes. 
Medium Clusters - source with notable "Sceptic Spells"; acquire quickly to cap poison chance.
Rare Jewels - source relevant 1-2stat rares
NOTE: Make sure to get at least one jewel with CORRUPTED BLOOD CANNOT BE INFLICTED ON YOU. Without this, corrupted blood will tear you to shreds in a matter of seconds.
