Guide notes
September 25, 2019
-Updated for Patch 3.8


In Patch 3.5 many Cold skills got reworked and also Cast on Critical Gem's cooldown was lowered 0.5s to 0.15s, letting it proc up to 7 times per second! This change made Cast on Critical Strike based builds one of the strongest in the game. This build is focused mainly on triggering Ice Nova and Frostbolt with Cyclone, but it fits all kind of Cold spells really well, so if you prefer to play Glacial Cascade or Freezing Pulse, you don't need to change anything except the desired Spell Gems. The only required, and the most expensive item in this build is Cospri's Malice, the rest is focused on stacking as much Critical Strike Chance and Multiplier as possible.

1. Gameplay

Gameplay is pretty straightforward - you Cyclone into packs of monsters and trigger all your socketed Cold Spells. The more monsters, the more spell casts per second. It's one of the most satisfying and fastest map-clearing builds in the game, thanks to cold explosions and ice projectiles flying all over the screen. Getting high Attack Speed is critical versus Bosses, as you increase the number of Hits per second, and trigger your Spells more frequently.

3. Leveling tips

This build feels really good, when you have all gear required for it and leveling Cast on Critical strike might be hard, that's why we recommend using Frost Blades for leveling, until you hit level 68, when you can wear all the required unique items. During leveling focus on upgrading your weapon to the highest Elemental/Physical DPS you can find.

Suggested leveling Gem setups:

Frost Blades setup
Frost Blades Frost Blades - your primary DPS source. We are using it for the entire leveling process
Added Cold Damage Support Added Cold Damage Support - a lot of additional Cold damage
Ancestral Call Support Ancestral Call Support - it will hit two additional nearby enemies with Frost Blades, which helps a lot with clearing packs
Elemental Damage with Attacks Support Elemental Damage with Attacks Support - increases Elemental Damage
Utility Gems
Ancestral Warchief Ancestral Warchief - great totem, that deals a lot of damage against Single targets but also increases Melee Damage
Herald of Ash Herald of Ash - grants increased Burning Damage and causes slain monsters to Ignite nearby monsters for a percentage of the overkill damage
Herald of Ice Herald of Ice - additional Cold Damage and Ice Explosions that shatters whole packs of monsters
Whirling Blades Whirling Blades - your primary mobility skill


We recommend killing all the Bandits for two additional Passives Points or helping Alira if you prefer additional Mana Regeneration and making it easier to cap Elemental Resistances
