Why Cold DoT?

• dont require transformation/transition after leveling 10 Acts, every gems can access via main quest lines, mean smoother gameplay.
• very SSF friendly, or very budget friend if you play trade league, dont require cluster jewel
• Chill, Freeze and not require stand-to-fire make the build very safe to play, less dying mean fast leveling (I reached lvl 93 in 1st day of league).
• shieldddd chargeeeeeee
• S tier all-rounder build, A+ mapping, can do all content even uber-bosses.... I can't ask for more from a build.

Chosing Class/Ascendant

• Elementalist (recommended): Large AoE, immu to reflect
• Occultist: Native Explosive, high DPS
• Trickster: Easy cap Spell Suppress, balance and tanky

Both Elementalist and Occultist have potential to access other ascendant node via Forbidden Fresh/Flame jewels.

Lets begin!

Stage 1 - After 10 Act and early Atlas progress

I dont have anything to say much about 10 acts, it feel like easy mod, 4L is everything we need to kill Eater/Exarch.

First 31 Atlas Points: https://poeplanner.com/atlas-tree/BAAIAB8AXz54gIsuhCqn4iFgMPoo57VmfVqN6tlbt12L4X2R3v4pjYIZ3YNOG6LQxB-u7xN9GIsLcTPGiaOpQ2Yfh9QUAB-LCAAAAAAAAAMDAAAAAAAAAAAA

46 Atlas Points with Wandering Path: https://poeplanner.com/atlas-tree/BAAIAC4AXz54gEz1iy6EKqfiMPoo57VmfVqN6k_32Vsdfbddi-F9kZtYJ3Xe_p7YKY1w492D567TDuEQfbXrX8SFThui0CQyxB8TfdKeC3GP5TPGiaOpQ7VjZh_UbIfU0CgUAB-LCAAAAAAAAAMDAAAAAAAAAAAA

This atlas tree promise 100% change to drop map and 80% chance to +1 Tier Map help you progress Atlas Quest line and reach T16 as fast as possible.

Some notes:

• Unique Helmet is most p/p upgrade. "Eye of malice" is BiS, "Rime Gaze" is great too.
• 4/5L Carcass Jack is next upgrade, every mods on this body are useful for the build.
• Do Jun mission to unlock "Cold DoT Mul" craft on weapon.
• Looking for +1 cold/all scepter with open suffix to craft "Cold Dot Mul".
• Looking for +1 cold/all amulet
• Looking for +1 cold shield.
• Leveling Vaal Cold Snap

Stage 2 - Mid game, Unlock Atlas

Atlas: https://poeplanner.com/atlas-tree/BAAIAG0AXK1fPpbneICJEUz1sRV5d4suStACWIQq_sVagYn-p-LUuTD6KOduo1JollAspdqmjEG1Zn1l3HLJ_de-fVqN6lL2fONP9xqs2VtGOoyRHX1d0-T3t12L4X2RCnubWCd13v6bd6CC2kQkpZ7Y0LzQxjBkEwUpjXjCMIlw45zH0nDdg-eu0w7hEH21XNjrX8SFTdxOG6LQyxc1MCQy15LEHxN9Ku7SnsABwa8LcT59_iVXFI_lAzAAf3NEM8ZIEtVp5Z-Jo6lDtWNmH9RsZP3VOYfUK7dP5uln0CgUAB-LCAAAAAAAAAMDAAAAAAAAAAAA

Alter and Go with low investment and finish your atlas.

At this stage we need invest a bit to dps to help us kill end game boss:

• Mark of the shaper + some good Elder ring
• Legacy of the Fury (if trade league), or spam exarch/eater currency on rare boots looking for "Drops Scorched Ground while moving, lasting # seconds"
• Acquire "expose cold on hit" and "cold dot mul" on rare gloves via spaming exarch/eater currency.
• Arcanist Brand - Frost Bomb - Frostbite - Elem Weakness is your best friend for single.
• Upgrade weapon, shield, amulet.

Stage 3 - Late game, Focus farming

Atlas: https://poeplanner.com/atlas-tree/BAAIAH0A29aW50z1svqxFe-6eXeFX66lEKwZiItO20ZK0AJY_sUa34n-1Lkw-mFTbqNSaE3DllAspdqmjEGkNH1l3HLJ_de-jepS9msxqVh84xqs_DdGOsODXdPk9wp73GkfrOfZm3ewlKCC2kQkpdcrT12Lc57YDs_QvNDGMGQrnM-jEwUT7UVYeMIwifgJcOOcx8SR-vjScOeu5cjTDuEQs39c2MLJYU9OG02Ryxc1MNXq15ITfQ75CxIq7ixIwa_l7MEkPn1XFBc9cQtj0QPtj-UDMAB_c0QzxhN10YruZEgS1Wnln6lDtWNmH0ls2E9k_dU5-1Mrt0_m6WfQKBQAH4sIAAAAAAAAAwMAAAAAAAAAAAA=

• Map: Cemetary
• Scarab: Ambush, Expedition, Breach, Divination
• Kirac mods: Ambush

After done with end-game bosses, we can drop a bit of DPS inexchange of clearspeed and QoL:

• Looking for Asenath with "Curse Elem Weakness on Hit"
• Craft Elder/Redeemer ring with "Curse Frostbite on Hit"
• Looking for "Expose Cold on Hit" in Crucible Weapon Passive Tree
