Sorceress Frostbolt Comet Endgame Build

Introduction

This guide has been fully updated for The Third Edict League (Patch 0.3.0).

The Frostbolt Comet Sorceress (Stormweaver or Chronomancer) features multiple Cold Spells to optimize gameplay for speed-farming maps and killing pinnacle bosses. To clear maps, Ice Nova freezes enemies to trigger a barrage of Frostbolt projectiles from Elemental Invocation. Against bosses, Frost Wall rapidly triggers Comet from Cast on Critical to rain down for massive single-target damage.

Disclaimer: While the Frostbolt Comet Sorceress is a viable endgame build. the Blood Mage version of the Frostbolt Comet Build is superior in all aspects, offering better damage scaling, survivability, and infinite “Mana”. Even if you already have a high-level Sorceress, consider rerolling to a Blood Mage for the best version of this build.

Strengths and Weaknesses

Build Mechanics

Snakepit

Snakepit is highly recommended in the left ring slot to remove the piercing effect from Frostbolt and cause the projectiles to fork. Frostbolt fires three projectiles per cast with Scattershot. Each of the projectiles fired split into two projectiles after hitting the first enemy and then explode on the second enemy. Against groups of enemies, Frostbolt explosions can shotgun targets to hit them multiple times. If you do not yet have Snakepit, this build can still be played with Frostbolt piercing through all enemies.

Boss Fights

In boss fights, Comet is rapidly triggered from Cast on Critical through multiple explosions from Frost Wall supported by Pinpoint Critical to reach 100% Critical Hit Chane.

Defenses

Maximum Life is set to 1 by Chaos Inoculation, so Energy Shield is utilized as an effective substitute for hit points. Stun Threshold from Energy Shield nodes are allocated in the Passive Tree.

Capping all elemental resistances to 75% is essential for survival. Chaos resistance is not needed, as this build is immune to Chaos damage due to Chaos Inoculation.

Skill Rotation

Follow the basic skill rotation below to progress through the campaign and clear groups of enemies in maps:

1. Cast Ice Nova to freeze enemies and trigger Frostbolt from Elemental Invocation. Ideally, you want to deal enough damage to freeze enemies in one cast, as spamming Ice Nova can rapidly drain your Mana pool.
2. If additional damage is needed against tough elites, cast Frost Wall on top of them for additional explosions.
3. Cast Snap to finish off any surviving enemies that are frozen.

Execute the steps below to optimize damage against bosses:

1. Before starting a pinnacle boss fight, fully charge Spellslinger by spamming Orb of Storms. Allow Orb of Storms to expire to collect Lightning Infusions for Frost Wall.
2. Approach the boss to cast Sigil of Power from a Chiming Staff equipped in Weapon Set 2 to buff damage.
3. Switch back to Weapon Set 1 (can be set to automatically swap) before casting Elemental Weakness to reduce the Resistance of the boss. Elemental Weakness can be pre-cast before a boss spawns if supported by Cursed Ground.
4. Cast Frost Bomb to apply Elemental Exposure.
5. Cast Frost Wall on top of the boss.
6. If you have charges for Elemental Invocation against map bosses, release all triggers of Frostbolt to hit Frost Wall for shotgun explosions.
7. Cast Spellslinger to release multiple triggers of Comet.
8. Once Comet starts to land, repeat casts of Frost Wall to continue the chain reaction.

Video Guide

The following video shows gameplay for the Blood Mage version of the Frostbolt Comet build. You can still get an idea of the playstyle for the Sorceress, as it is the same for both builds. The Blood Mage is better than the Sorceress due to infinite “Mana” and damage scaling from Life with Rathpith Globe.

Skill Gems, Spirit Gems, and Support Gems

The Frostbolt Comet Stormweaver utilizes the following Skill Gems, Spirit Gems, and Support Gems. Gem Sockets are listed in order of priority.

The starter setup provides the best Mana sustain. This setup requires 107 total Spirit to activate Cast on Critical and Mana Remnants. An optional Clarity II can be socketed into Mana Remnants with an additional 20 Spirit.

The Blink setup is designed for faster speed farming by replacing Mana Remnants with Blink, if you can manage Mana with enough Mana Regeneration Rate and Mana on Kill. This setup requires 137 total Spirit to activate Cast on Critical and Blink. Clarity I or Clarity II is still an option if you have an additional 10-20 Spirit remaining.

Ensure you apply 20% quality to the Cast on Critical skill gem and allocate Efficient Inscriptions in the passive tree to reduce the Spirit reservation Defeat The King in the Mists (Act 1), Ignagduk (Act 3), and Lythara (Interlude) to gain 100 base Spirit. Obtain the remaining 7-57 Spirit from your Amulet.

While clearing maps, activate Elemental Invocation to trigger Frostbolt. Craft a lower-level Elemental Invocation gem to reduce its Dexterity requirement (Level 13 recommended).

Against bosses, deactivate Elemental Invocation to instead activate Cast on Critical to trigger Comet.

Equip a Chiming Staff in Weapon Set 2 to unlock Sigil of Power, which provides a damage buff against bosses. Ensure you set all your other skills to only be used with Weapon Set 1, so you automatically swap back.

Orb of Storms can be crafted at Level 3 to reduce its Mana cost.

Perfect Jeweller’s Orb priority on Skill Gems: Elemental Invocation > Ice Nova > Cast on Critical > Frost Wall > Snap > Frost Bomb.

Ascendancy

Stormweaver is the recommended Ascendancy for the Frostbolt Comet Sorceress. The chosen Ascendancy can be changed by clearing your highest completed trial.

Stormweaver

The Stormweaver is the best Ascendancy choice due to the Mana Regen and damage increases within its nodes. Allocate the Ascendancy nodes in the following order:

1. Constant Gale and Force of Will — The Arcane Surge nodes are highly beneficial for more Mana Regen and increased Cast Speed.
2. Strike Twice and Shaper of Storms — Both these nodes need to be allocated for any effect. Cold damage applies 2 stacks of Shock for a massive increase in damage output. The benefit of these nodes become more effective as Shock/Ailment magnitude is increased.

Chronomancer

The Chronomancer is not usually recommended due to the lack of any Mana Regen or damage increases. The benefits are instead based on survivability. Allocate the Ascendancy nodes in the following order:

1. Footprints in the Sand — Temporal Rift can be used to instantly refill Mana after multiple triggers empty your pool.
2. Ultimate Command — Time Freeze is especially useful against bosses to deal uninterrupted damage without risk.
3. Apex of the Moment — Slow provides an additional layer of survivability.
4. Now and Again — Frost Wall gains a chance to not consume a Cooldown when used, allowing more casts.

Passive Skill Tree

In the Passive Skill Tree, use attribute nodes to fulfill any Strength and Dexterity requirements, and then allocate the rest as Intelligence for Maximum Mana.
