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) — A continuous beam of electricity.
Spark Orb (Secondary) — Charge up a slow moving 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 Charm slots
Smiting Spear — Throws a spear that sticks to enemies or scenery and pulses. Shooting a planted spear can trigger pulses.
One equipped Charm by default. Charm Power unlocks a second slot. The following choices are conditional priorities to find during a run.
- One-slot priority
- Gold Lure
- After Charm Power
- Gold Lure + Golden Ticket
Gold Lure is an early economy priority with more rooms left to encounter Loot Golems. Golden Ticket reduces purchase costs; neither is direct boss damage.
When to swap: Gold Converter replaces an economy pick only when you can afford to trade healing shrines for gold. For an isolated boss, replace an economy pick with Giant Slayer if available; keep Smiting Spear as the planned direct-damage answer.

Editorial priorities
These are planning goals, not Ancient Forge item names.
Sustained Primary uptimePrimary–Secondary overlapSingle-target insurance
Before you can use this setup
- Electrical Beam: Available when this weapon is unlocked.
- Spark Orb: Available when this weapon is unlocked.
- Smiting Spear: Defeat General Kri’su a second time. Climb the platforms that rise from the water and interact with the altar. Ability unlock details →
- Unlock Ancient Forge to find upgrades during expeditions. The listed upgrades are priorities, not guaranteed drops; Artificer permits a weapon and ability choice at the same Forge.
If a recommended mode is still locked, start with this weapon’s default modes (Electrical Beam / Spark Orb). Treat that as a temporary setup and pursue the listed challenges before expecting the full route.
Charm names link to their effects and challenge unlocks. Unlocking an item adds availability; it does not guarantee it will appear in your next run.
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
Deep Water 30 variant
Golden Skin keeps you alive while Exponential Gold does the damage; pair with ice Blessings to freeze rooms when overwhelmed.
