Overview
This is a min-maxed self-cast Spark showcase on the Gemling Legionnaire that deliberately avoids the popular Cast on Critical (CoC) trigger setups in favor of casting Spark directly. The pitch is a build that is almost unkillable while still delivering top-tier output in both content types — the creator rates it 10/10 for clear speed and 10/10 for bossing, with single-target damage strong enough to drop a boss in roughly a second.
Spark fires lightning projectiles that bounce around the arena, racking up hits as they ricochet, which makes it naturally strong at clearing packs and at piling damage onto a stationary boss. Going non-CoC means the damage is consistent and self-directed rather than gated behind crit triggers, trading some of the explosive ceiling of trigger builds for reliability and control.
This entry is built from the creator’s published build notes (the full guide and Path of Building live on their Mobalytics profile), so it captures the build’s identity and strengths; the precise gear, links, and passive choices should be confirmed against the source video and the linked planner.
Pros & Cons
Pros
- Self-cast (non-CoC) Spark gives consistent, controllable damage without crit triggers
- Rated 10/10 clear speed for fast mapping
- Extremely high single-target — boss kills in around a second
- Described as almost unkillable, with strong survivability layering
Cons
- A min-maxed showcase, so the headline numbers assume significant investment
- Specific gear and links are not fully detailed in the video description
- Self-cast playstyle is more active than fully automated trigger builds
- Lightning damage can struggle against lightning-resistant or reflect-heavy content
Key Skills
- Spark — self-cast lightning projectile skill, the build’s sole damage engine
- Gemling Legionnaire support package — leveraged to amplify gem effects and sustain (specifics to confirm against the source)
Gear & Anointments
The creator publishes a full Path of Building and gear list on their Mobalytics profile rather than itemizing it in the video description, so specific uniques, jewels, and anoints should be confirmed against that planner and the source video. The build is presented as a min-maxed configuration, so expect premium gear at the showcased power level.
Endgame Notes
The build is positioned as an all-purpose endgame option: 10/10 mapping clear paired with boss-per-second single-target, while remaining nearly unkillable. It is a showcase of the build’s ceiling rather than a budget progression guide.
