Overview
This Stormweaver Sorceress leans on Spark as its core mapping skill, with most of its lightning damage converted to cold through Call of the Brotherhood. The result is a hybrid lightning/cold caster that floods packs with bouncing Spark projectiles while a Cast-on-Crit setup throws out Comet for the heavy hits. The creator runs it as a level 95+ character and stresses that the build does not require that level to function — the experience is smooth enough that levels simply accumulate as you map.
The build is built around crit and elemental infusion. Frost Bomb seeds cold infusions, an anointed Infusion of Power converts consumed infusions into power charges, and Charge Regulation turns those charges into a large spell crit bonus. The net effect is that Spark sits around 69% crit baseline and climbs to roughly 85% once infusions are flowing, which keeps the Cast-on-Crit Comet firing reliably during clear.
Defensively the character is an energy-shield caster, sitting around 4.3k ES with near-capped resistances. The creator is open about a few rough edges — notably that Spark projectiles can get stuck in tight terrain like Abyss cracks — but frames the build as a strong, low-effort mapper that excels in mechanics such as Ritual, Breach, and Abyss.
Pros & Cons
Pros
- Excellent pack clear from bouncing Spark projectiles converted to cold
- Cast-on-Crit Comet adds big burst damage without extra button presses
- Very easy and low-effort to pilot once the crit/infusion engine is online
- Strong fit for Ritual, Breach, and Abyss farming
- Scales smoothly into high-level endgame without a strict gear floor
Cons
- Spark projectiles can get stuck in tight geometry such as Abyss cracks
- Crit and infusion dependency adds setup complexity and gem-link demands
- Energy-shield pool is modest (~4.3k), so survivability needs respect
- Leans on specific uniques and crafted gear, making it gear-hungry rather than a true budget build
Key Skills
- Spark — primary clear skill, lightning damage converted to cold for bouncing pack coverage
- Comet — triggered via Cast-on-Crit for high-damage burst on critical hits
- Frost Bomb — generates the cold elemental infusions that fuel power charges and crit
- Orb of Storms — supporting cast that helps maintain triggers and pressure
- Sigil of Power — buff skill boosting damage during mapping
Gear & Anointments
The character is an energy-shield Sorceress with resistances kept near cap and a focus on spell crit, cast speed, and spell damage. A crafted staff providing +5 to all spell levels along with spell critical chance, cast speed, and spell damage anchors the offense. Energy shield is spread across the helmet and body armour, with the amulet adding spirit, skill levels, and spell damage.
- Staff — +5 to all spell levels, spell crit chance, cast speed, spell damage (creator-crafted)
- Call of the Brotherhood (topaz ring) — converts lightning damage to cold
- Maligaro’s Virtuosity ring — raises the critical damage bonus cap to 250%
- Amulet — double spirit, all spell skills, spell damage; anointed with Infusion of Power
- Belt — cast speed/damage while using a flask
- Jewels — a Timeless jewel plus crit/energy-shield jewels (Heart of the Wheel diamond, sapphire for cold resist)
The amulet anointment is Infusion of Power, which grants a power charge whenever an elemental infusion is consumed. Combined with Charge Regulation on the tree, those power charges translate into a large spell crit bonus. Exact item rolls and any additional uniques should be confirmed against the source video.
Endgame Notes
The build is positioned squarely as an endgame mapper rather than a dedicated boss-killer. The creator highlights Ritual, Breach, and Abyss as standout content, and notes that DPS scales further with better jewels and amulet rolls than what is shown in the recorded footage. Passive choices like Storm’s Recollection (re-collecting infusions a few seconds later) and considerations around Tempest and Elemental Storm reflect ongoing optimization toward higher map throughput.
