Best Tesla Gun Build in Abyssus
Best Tesla Gun build at a glance
The Tesla Gun is the most forgiving recommendation for crowded rooms because its chains reduce the cost of imperfect aim. Goldburst is the scaling route here, but it still needs a plan for isolated bosses.
- Primary fire
- Electrical Beam
- Secondary fire
- Spark Orb
- Aspect
- Goldburst (Fortune)
- Weapon Forge
- Spark Gap · High Voltage · High-Frequency
- Ability
- Smiting Spear
Chain lightning arcs between nearby enemies, making the Tesla Gun forgiving in clustered rooms and well suited to repeated-hit Blessing triggers. It needs less precise tracking than the roster’s weakpoint weapons.
Best for: Crowded arenas & solo runs — effortless room control
Recommended Tesla Gun build
Rapid chains create frequent status opportunities. Goldburst turns carried gold into a scaling route, while Golden Skin adds stability; balance purchases against the benefit of preserving that economy.
Primary and secondary fire
Electrical Beam (Primary) — Continuous beam of electricity.
Spark Orb (Secondary) — Slow orb that zaps nearby enemies.
Best Aspect and Blessings
Alternatives: Chain Lightning
Exact weapon Forge picks
- Spark Gap — Increase fire rate the longer you fire without letting go of your Primary.
- High Voltage — Deal 20% more Primary damage to enemies currently being hit by the Secondary.
- High-Frequency — Increases range/radius of your Secondary by 50%.
Ability and Charms
Smiting Spear — Hurl a spear that strikes a target area — a top damage ability that pairs with Activate Gun Mode.
Editorial priorities
These are planning goals, not Ancient Forge item names.
Sustained Primary uptimePrimary–Secondary overlapSingle-target insurance
How to make the build work
- Take an early repeated-hit payoff such as Goldburst, then keep Electrical Beam on clustered targets.
- Use Spark Orb with High Voltage so Primary and Secondary damage windows overlap.
- Reserve at least one slot for single-target damage or a burst ability before late bosses.
Solo, co-op and boss adjustments
Solo route
Use the weapon as moving crowd control: sweep across the first target in a cluster, keep circling, and let arcs reach enemies that would otherwise demand precise tracking.
Co-op role
Aim at the densest group rather than copying a teammate on one target. Tesla is most valuable when it removes small threats while precision weapons handle elites.
Boss plan
Chains lose value against an isolated target. Smiting Spear, Giant Slayer, and a raw-damage option prevent the build from becoming a room-clear specialist with no boss finish.
Common mistakes
- Treating a large gold total as a substitute for defense
- Taking several conditional payoffs without a reliable trigger
- Spending every slot on room clear and entering a boss with no burst option
Depth 30 variant
Golden Skin keeps you alive while Exponential Gold does the damage; pair with ice Blessings to freeze rooms when overwhelmed.
