Overview
This Ritualist build turns Spark into a screen-filling lightning caster. Spark projectiles pierce through packs and keep bouncing around the area while you stay on the move, so mapping is about casting from range, stepping forward and letting the lightning clean up corridors and open rooms. Rather than face-tanking, the build controls the pace of every fight with heavy slows.
Blasphemy carries Temporal Chains and Vulnerability, so anything near you moves slower and takes more damage, and Convalescence adds recovery and extra breathing room. The damage ceiling comes from critical strikes: crits from Spark trigger Comet through Cast on Critical, giving real burst against rares and bosses. Mana is a central resource because Archmage is a major part of the scaling, which makes mana sustain and mana stacking a priority from the start.
Pros & Cons
Pros
- Outstanding screen coverage and ranged clear (creator rates mapping 5/5)
- Temporal Chains slow makes dangerous packs much easier to handle
- Cast on Critical Comet adds big automatic burst on tougher targets
- Solid early game loop thanks to ranged clear and curse control
- Scales with Archmage, mana, crit and cast speed as gear improves
Cons
- Low crit chance makes Comet triggers feel inconsistent
- Weak mana sustain makes Spark clunky to cast
- Still punishes you if defences are neglected
- More moving parts than a one-button build (curses, triggers, several elemental tools)
Key Skills
- Spark — main damage and clear, linked with Pierce, Rapid Casting, Prolonged Duration and projectile/damage supports
- Comet (Cast on Critical) — triggered burst from Spark crits for rares and bosses
- Blasphemy + Temporal Chains / Vulnerability — slowing and damage-taken curse aura, with Slow Potency and Magnified Area
- Purity of Lightning — defensive aura against lightning damage
- Convalescence — recovery, uptime and mana sustain with Second Wind, Cooldown Recovery and Clarity
Gear & Anointments
Prioritise lightning and spell damage, critical strike chance and damage, cast speed, projectile speed, mana and mana sustain, cooldown recovery and defensive layers. Mana matters as much as damage because Archmage drives the scaling. The creator also mentions Crushing Fear coming from the gear setup and Gemling Legionnaire support as a scaling option. Exact uniques and anointments are to be confirmed against the source video and its linked PoB.
Endgame Notes
On bosses, stay at range and keep Spark hitting so Comet keeps triggering; pull out Frost Bomb, Orb of Storms, Fireball and Elemental Conflux for extra elemental pressure when a target is tanky. Positioning and constant movement matter more than raw tankiness.
