[3.1] Crit Glacial Cascade Miner Shadow (Saboteur)

Intro & build description

This has been my go-to build when playing Harbinger league and it allowed me to complete every bit of content game has to offer, including guardians, Shaper, Uber Atziri, Pale Court, Hall of Grandmasters – you name it. It has decent survivability because of MoM keystone and solid amount of unreserved mana, very high AoE and damage which allows us to clear very quickly and from safe distance.
It’s great as a league starter build because it doesn’t take a lot to get it going and it scales extremely well with some investment.

Essentially this build is the same as Ziggy D’s GC miner, but I pushed it to the limit and made some adjustments to better fit my playstyle.

Build Pros

  • Can do all the content game has to offer
  • Can do all map mods
  • You can forget about reflect

Build Cons

  • Some people don't like mine builds as a concept

Hubris Circlet / Eternal Burgonet

Main thing to look for when searching for helmet is the enchantment – 40% increased Glacial Cascade Damage.

Best bet is to buy white Hubris Circlet with aforementioned enchantment and craft it yourself.

Stats to aim for when crafting is as much life as possible and some resistances. Energy Shield and maximum mana are nice bonuses.

Body Armour

Carcass Jack

Great offensive body armour for the build – gives us nice balance of life, some resistances, AoE and damage.


Fingerless Silk Gloves

Ideally look for Fingerless silk gloves with as much life and resistances as you can.

A pair of Sorcerer gloves is a nice alternative.


Two-Toned Boots

Look for Two-Toned boots base with 30% increased movement speed, as high life and resistances as you can find.

Great enchantment for the boots is – “Damage Penetrates 10% of Enemy Elemental Resistances if you haven’t Killed Recently” if you by some miracle have capped resistances.

Left Ring

Diamond Ring

Look for Diamond Ring with as much life and resistance as you can.
If you have capped resistances, you can look for ring with open suffix and use Elreon to craft Increased Critical Strike chance on the ring for even more damage.

If you need it, use ring to get some attributes that you lack.

Right Ring

Essence Worm

Wear Essence Worm and put Hatred aura in it.
Having no mana reserved synergizes well with Clear mind jewel which gives us increased spell damage while no mana is reserved.


Citrine Amulet

Ideally look for amulet with global critical strike chance and multiplier. If there is open prefix you can craft life because having high life and both crit mods will make amulet expensive.

You can also use different base if you have problems with attributes such as Jade or Amber amulet.


Leather Belt

Look for Leather belt with as much life and resistance as you can find.

Great idea is to get belt with life, 2 resistances and an open suffix – that way you can use Tora to craft “#% increased Trap Damage / #% increased Mine Damage” mod on the belt.

2Hand Weapon

Tremor Rod

The most important item in our build is Tremor rod – staff that’s essentialy a 7-link. 6-linked Tremor Rods are expensive but it works very well as a 5-link and even 4-link.


Builds Jewels

Stats to look for on jewels:

1.) Increased crit chance with cold / elemental skills etc
2.) Increased crit multiplier with cold/ elemental skills etc
3.) Increased Maximum life
4.) Increased Cold / Spell / Mine / Area Damage
5.) Resistances and attributes if you are lacking


Clear Mind

Use this jewel for boost in spell damage.


Flask Setup

1.) Divine Life flask with instant recovery and bleed removal
2.) Divine Life flask with instant recovery and freeze removal
3.) Lavianga’s Spirit (very nice flask for the build)
4.) Quicksilver flask of Adrenaline
5.) Atziri’s Promise

How to play the build:

Place mines -> Detonate, if something is still alive, detonate additional time because Tremor Rod allows us to do that. Repeat.

This build also uses Spell Totem & Detonate mine combo, which means we summon Spell Totem that will instantly detonate your mines for you when there are monsters in range. This allows us to dish out extreme amounts of damage on bosses. I also mentioned Lavianga’s Spirit flask; because mines are very mana hungry, this flask is ideal because it allows us to spam mines with no mana cost while it’s affecting us.

We also use Frost Bomb Traps that serve 2 purposes – frost bomb reduces target’s cold resistance and because of Bomb Specialist ascendancy node, we get 8% increased damage for each trap we have on the ground.

Typical Spell and flask rotation for bosses:

Put Orb of Storms on top of boss to apply Elemental Weakness -> Throw one of your Frost Bomb Traps on the boss to reduce it’s resistance -> Throw as many traps as you can in a place they won’t be triggered for damage bonus -> Put down Detonate mines Spell totem -> Drink Atziri’s Promise -> Start Placing as many mines as you can, when your mana drops to around half or 1/3, drink Lavianga’s Spirit and continue placing as many mines as you can while avoiding hits from boss.
Using this tactic, you should be able to deal enough damage to take down even the toughest bosses but be careful not to get hit.

Hall of Grandmasters tips:

This build is excellent Hall of Grandmasters farmer.
To do this map, it’s suggested to have searing touch with Scorching Ray setup for the Energy shield grandmasters. You should also swap out Concentrated Effect Support for Increased Area of Effect because the damage is sufficient.

How to do this map:

Place mines while keeping yourself in safe distance from the energy barrier -> move closer to the energy barrier and release the grandmasters -> detonate 2 times. If they are not dead yet, place new mines and detonate. For energy shield grandmasters use scorching ray setup.

About gems

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


  1. I played ziggy’s build last league and am using it this league as my leaguestarter but i am planing on going low life later on. I do not believe there is a benefit to throwing all of your frost bomb traps on top of the boss. You get bonus damage for each active trap but that bonus disappears once the trap is triggered. Ideally you want to pop one trap on the boss for the debuff and then you want as many active trap as possible on the ground to get the damage buff.

  2. How to level with this build?

    • gems

      Blade vortex at first and as soon as you get lvl 28, find 4-link and use Glacial Cascade – Remote Mine Support – Trap and Mine Damage Support – Minefield and you are good to go until you get Tremor rod.

  3. What items to get to survive with this build?the ones you recommand kinda don’t help me

    • gems

      With items I recommendded you should at least have 4300-4500 life, some ES and more than 1000-1400 unreserved mana which allows you to survive hit or 2 even in T16 maps. You can always get different chest piece like Belly of The Beast or rare armor chest with 130+ life, but these items are pretty optimal for the survival.

  4. I’m playing this build, or close to it, and it’s really great. I am still wondering though, with weapons, asides from the staff you are using, if spell damage, physical damage, or global crit are the way to go. Since Glacial Cascade deals physical damage, would increased physical damage in weapons and other places improve this, or will that only apply to attack skills? And is spell damage or crit chance/multiplier more important?
