Lexyu's Winter Orb Occultist Build Guide (PoE Curse of the Allflame 3.29)

Introduction

The Winter Orb Occultist (Witch), featuring Herald of Ice, is a ranged spellcaster build that speed-farms maps with blazing fast mobility and massive screen-wide explosions. Winter Orb fires auto-targeting projectiles while you fly through maps with Frostblink of Wintry Blast, causing Herald of Ice to chain explosions to kill enemies off-screen.

Patch 3.29 Update

“Winter Orb: Now fires 2-3 Projectiles at gem levels 1-20 (previously 1 at all gem levels), has 25% chance to Freeze, and a Critical Strike Chance of 7.5% (previously 6%). Now deals 360 to 539 Cold Damage at gem level 20 (previously 360 to 450).”

The 3.29 Patch Notes buff Winter Orb with higher base Critical Hit Chance, more damage, and 2 additional projectiles, making it a top starter build for the Curse of the Allflame league.

Build Mechanics

Winter Orb (WOrb) is an ideal skill for this build due to its rapid hit rate and 7.5% base Critical Strike Chance. Multiple projectiles are fired at a time, overlapping explosions to shotgun enemies with every hit.

The build focuses on damage scalars that apply to Winter Orb, Frostblink of Wintry Blast (FoWB), and Herald of Ice (HoI), such as Power/Frenzy Charges, Increased Cold/Generic Damage, Added Cold Damage, Critical Strike Chance, and Critical Damage Bonus. Herald of Ice explosions are considered Secondary Damage, so they do not benefit from bonuses to Attack or Spells, such as Increased Spell Damage or Archmage Support.

Corpse Pact from the Necromancer Ascendancy is granted by Forbidden Flesh and Forbidden Flame to gain 4% Increased Cast Speed for each corpse Consumed Recently, up to a maximum of 200%. This massive speed boost is easily fully ramped up by Devour Support on Frostblink of Wintry Blast and Herald of Ice, especially when clearing enemies during high-density activities. Against bosses, Arcanist Brand linked to Desecrate and Volatile Dead ramps up the increased Cast Speed buff and applies Shock from Corpse Pact.

Multiple layers of defense enhance survivability. Life and Energy Shield are combined for a high effective hit pool. Attack Block, Spell Block, and Evasion are utilized to reduce incoming hits. Energy Shield Leech is relied on, so scale damage output to quickly recover any damage taken.

Playstyle

Channel Winter Orb to build up its stages, and then hold down Frostblink of Wintry Blast to quickly traverse and kill most enemies while mapping, causing chain explosions from Herald of Ice to blow up everything multiple screens away. If more damage is needed against tougher enemies, continue to channel Winter Orb for maximum damage output.

Against bosses, a simple skill rotation can be executed to deal maximum damage:

1. Before the boss spawns, channel Winter Orb until you reach maximum stages.
2. Cast Arcanist Brand on the boss to automatically activate Desecrate and Detonate Dead, ramping up the Increased Cast Speed and applying Shock from Corpse Pact. Recast Arcanist Brand every 3 seconds to maintain the buff.
3. Hit the boss with Frostblink to apply Frostbite with Hextouch Support.
4. Continue to channel Winter Orb for maximum damage output.

Map Modifiers to Avoid

Certain combinations of modifiers on maps can increase difficulty, such as stacking multiple monster damage modifiers. You should figure out which modifiers your current build struggles with from experience. The following list of modifiers can cause issues and may need to be avoided entirely.

• ❗Players cannot Regenerate Life, Mana, or Energy Shield
• ❗Monsters Reflect Elemental Damage
• ❗Players have less Area of Effect (can prevent explosions from overlapping, reducing single-target damage)
• ❗Monsters Steal Power/Frenzy Charges on Hit
• ❗Monsters Avoid Elemental Ailments (can prevent Herald of Ice from exploding)
