Build uniques / Example rare gear

Tip: Click on the item to view it on PoE Wiki or to view similar rare items in poe.trade


Devoto's Devotion

Great helm for the build since it gives 20% increased movement speed and some attack speed.

You could also go for rare helmet with high life and resistances if you need some more survivability.

Body Armour


Great all-around chest armor for any crit build.

Carcass Jack would be another nice option.


Rare Gloves

Try to get gloves with at least 80 life and as high resistances as possible since we need them a lot.


Bubonic Trail (2 Abyssal Sockets)

Look for Bubonic Trail boots with 2 Abyssal Sockets.

Left Ring

Mark of The Shaper

Mark of Shaper is a great ring for the build since we rely on spell damage.

Right Ring

Rare Elder ring

Look for rare Elder ring with Warlord’s Mark on hit mod. Craft life or resistances on top of that mod.


The Pandemonius

Pandemonius is exceptional amulet for any build that relies on cold damage.

Will most likely be quite expensive early on though.


Stygian Vise

Get a rare Stygian Vise with at least 80 life and as much resistances as possible.

1Hand Weapon

Cospri's Malice

One of 2 core items for the build – get it as soon as you can.



Another core item of the build – this shield makes sure we can forget about accuracy rating and always hit enemies.


Watcher's Eye

Look for Watcher’s Eye with “You have Phasing while affected by Haste mod”.

This jewel is not an item of immediate necessity, but it’s really nice to have later on.


Frozen Trail

We need 2 of these jewels to give our Frostbolt extra projectiles without Greater Multiple Projectile support gem and it’s damage penalty.


Rare Jewels

To cap resistances on this build, we will be using jewels.
Mods you should be looking for:

1.) +x% To all elemental resistances (Until you are capped)
2.) Any critical multiplier mod
3.) Increased maximum life
4.) Cold damage to spells mods
5.) Attributes if you need them


Flask Setup

Build uses following flasks:

1.) Divine Life Flask with instant recovery and bleed removal
2.) Diamond Flask with freeze removal
3.) Quicksilver Flask of adrenaline
4.) Sulphur Flask with curse removal
5.) The Wise Oak

About gems

Always tries to keep up with the game, its ever-changing mechanisms and explain them in understandable manner.


  1. what abyss jewel to put in boots?

  2. How did you solve the mana problem specially during boss fights?

  3. and up to how many resist should I need? I already spent 2ex per jewel(3pcs). (crit modifier,cold damage,life, resist). fire and light resist already hit 80+ while cold is 120 with the pandemonius but without the gloves and rings. Should I invest more resist to my rare ring + gloves or focus on Life and chaos resist coz its negative?

    • gems

      Just get them to 75% in maps as a minimum. Elemental weakness maps might be a bit dangerous, if you want to negate that mod, go for at least 109% of each resistance (but higher cold res for the Wise Oak).
      Getting 100+ total elemental resistance + high life on gloves would actually be kinda cheap, so you could go for that and of course, you could craft resistances on your ring as well. But don’t bother getting any chaos resistance.

  4. what are the best enchants for helm,gloves and boots?

    • gems

      For helm, any Ice Nova enchant would be good, Frostbolt damage, chance to freeze too. On boots look for either adds x – x lightning damage or damage penetrates 10% of elemental res.

  5. Any leveling tips for this build?

    • gems

      Level it as a spellcaster, Blade Vortex works really well. With Tabula, you should have no problem getting it through 10 acts.

  6. I can only see a small part of the passive tree. Is there any way you can post a pic of the whole tree for me please

  7. best pantheons sir?

  8. How will warlord’s mark change work with this build in 3.7? Will mana sustain be a problem now?

  9. Are there any improvements or nerfs with this build in 3.7?

    • gems

      There are most likely improvements with the new Legion jewels, but it has to be tested out yet. Warlord’s Mark has been nerfed so you can only leech with attacks, but it shouldn’t impact the build that much.

      • So…should we use a warlords ring to pair with the shaper ring still or find another elder ring?

        • gems

          Warlord’s Mark still works with attacks, so it should work with Cyclone. It’s also great for generating endurance charges. Personally, I’d prefer Warlord’s mark ring over regular Elder ring, but one without the curse can work as well.

  10. I am curious as to why have CoC in the body armour when you have Cospri’s? When the body armour sockets could be used for increasing Cyclone.

    • gems

      Since we scale spell damage, scaling Cyclone would be wildly inefficient. Cyclone is only used as a trigger for other spells.
