Build Overview

This is a Chinese build archetype first showcased here by 可布和常常诶, and then popularized on Witchhunter by Lazy Exile - who is an amazing build making and content creator. If you're interested in their variations please go check them out!

This build relies on Frostbolt with Breachlord's Amalgam to INFINITELY Proliferate with Mirror of Refraction. Each Frostbolt that hits the Mirror of Refraction will split into 10-12 projectiles and then return to you via Breachlord's Amalgam and if you stack enough CDR you will be spawning mirrors at like 2-3 per second which means you can ramp forever and be able to just have thousands of Frostbolts flying around your screen at any moment. There becomes so many that the game gives up and doesn't even show their animation making this one of the builds that has the MOST visual clarity in the game.

Our Defences are phenomenal, our Damage can quite literally scale to infinity, the only stopgap is mobility, which can scale infinitely as well, but at a higher investment than normal. This is because we need to balance our mobility with the speed of our Frostbolt and the CDR of our Mirror of Refraction.

The only important pieces for this build are Atziri's Rule for Mirror of Refraction and a high quiver effect Widowhail and well rolled Drillneck (high crit and damage). Everything else is completely up to your ingenuity to balance out. Because Frostbolt snap shots Drillneck, and we pierce infinitely we essentially get max crit chance and like 100's if not thousands of increased damage from our quiver. As a result the rest of the gear and tree can focus on scaling defenses or utility.

DEFENCES: We can GIGA invest into defenses since our weapon setup gives up so much damage. Because Gemling is OP we can get insane amounts of %inc Armour from Arctic Armour alt quality and we can also invest heavily into Evasion and ES. These layers of defense all work multiplicatively with each other to create a MONSTER TANK with only 8.5K ES which Can be scaled on all vectors pretty insanely

Strengths and Weaknesses

  • Tanky AF - Can easily reach 50k Ehp on 200D Investment
  • Infinitely Scaling Damage
  • Legitimately 0 button playstyle
  • Not Super Expensive (only 3 mandatory pieces of gear)
  • Can Get 150+ Rarity on Low-Mid Investment
  • Mobility requires higher investment/isn't straight forwards scaling
  • Build can be hard to understand (uses really cool tech)

Build Variants

HOW IT PLAYS:

The way this plays is we main hand our staff to setup Mirror of Refraction then fire 1 Frostbolt into a mirror and then swap back to our Atziri's Rule to keep spawning Mirror of Refraction and then this will start an infinite chain reaction where we will just spawn a growing amount of frost bolts. Eventually there are too many Frostbolts that the game stops showing them visually but they will still be there doing damage.

You can check if the invisible chain reaction is still going by 1. if your Cast on Critical is still proccing Refutation or Frost Wall or self cast Frost Wall and see if the walls are exploding or not.

FAQ:

My Chain Keeps Breaking:

If you notice that your chain is constantly breaking this is either because you're in a reduced CDR map OR that your Proj speed is too high. In which case reduce proj speed on Jewels and remove Projectile Acceleration III from your Frostbolt

How Do I Increase Mobility?

The one downside of this build is that cranking up the mobility is a 3 part equation. Normally, that faster you run or dodgeroll the faster you are. But for us to increase mobility we need to increase 3 things simultaneously.

1. Our Movement Speed
2. Projectile Speed
3. Mirror of Refraction Spawn Interval

1. You Can increase MS From Boots + tree + Runes/Dodge Roll distance (Cast on Dodge quality)
2. You Can Increase Proj Speed With Supports Like Projectile Acceleration III, Jewels With Proj Speed, Tree Nodes
3. You Can Increase Mirror of Refraction Spawn Interval Through + All Levels NOT Spell Skill Levels and through CDR on Jewels, Tree, Gear, and Supports (Cooldown Recovery II)

All gear affixes are in the their respective notes, but for jewels Specifically you can just slam on Liquid Envys on Emeralds that have any combination of %inc EV/Proj Speed/% Inc quiver bonus


Heroic Tragedy - any of these are fine as long as it has Vorona To Convert Elemental Equilibrium to Black Scythe Training For %ES This Roughly Equates to 80% Increase ES

The MOST important thing is lowering the mirror spawn interval of Mirror of Refraction. We can do this by two ways - CDR and Levels to Mirror of Refraction. CDR we get on legit every possible slot - Jewels, gear, supports wherever. This is an insane multiplier to both our damage and the consistency of our chain. We can increase the level of the Mirror of Refraction only by having a higher base level on staff (worth to perfect flux) and also by using Dialla's Desire.

We can use unset rings to get 2 more skills for Virtuous Barrier and then We socket in whichever support colors we need to balance out Gem Studded for Crit Immunity (HUGE)

The Important things here are:

1. Frostbolt - Rakiatas/Cold Pen - Verglas For Frost Wall (high Gain as cold) - Projectile Acceleration III (this makes the bolts go faster but also scales our Damage)

***IMPORTANT*** If you're breaking your chain too often (Frostbolts Fizzle out and stop killing mirrors) it's often time because your proj speed is TOO HIGH. So take out Projectile Acceleration III if this happens)

- Breachlord's Amalgam THIS IS 100% REQUIRED FOR THIS ENTIRE MECHANIC TO WORK - It makes all projectiles return to you so that they can then chain off the Mirror of Refraction.

- After this you can go damage - Zenith II, Deliberation, Elemental Focus all work (Zenith is best though because it snapshots off the first cast)

2. Frost Wall - This is OP and we put it on Cast on Critical to completely automate the engine. It gives use Verglas gain and also counts as "enemies" for pierce on our Drillneck and does a good amount of damage itself

3. Mirror of Refraction Not much to say here - get as much + level and CDR here. Cooldown Recovery II is required and then Uhtred's Augury and Dialla's Desire or just Uhtred's Omen if you can't afford the previous two

4. Arctic Armour - The supports don't really matter too much, You can go damage route or utility route here and both are ok - this is primarily for the Gemling Legionnaire alt quality which gives us ~280% increased Armor.

5. Convalescence with Uhtred's Constellation is nice since we're Chaos Inoculation

6. Refutation in our Cast on Critical also gives us a little bit more defenses

7. Charge Regulation gives us MORE Arm/ES/EV since we have Thaumaturgic Generator on amulet annoint and Resonance which converts our power charges into Endurance Charges

All Other Skills + supports are solely for balancing our Gem Studded or getting more defenses from Virtuous Barrier
