"Fire out lightning that hits 3 (+2 per stack) enemies for 200% base damage every 0.5s. The Tesla Coil switches off every 10 seconds." Red legendary item. Fires bouncing lightning in a 35m radius while active, cycling on and off every 10 seconds (50% uptime). Each bolt deals 200% damage with 0.3 proc coefficient and ignores terrain. Stacking raises the number of targets per bolt, not the damage or frequency. Best on melee survivors who stay inside the 35m range.
Wake of Vultures spreads elite effects through every Tesla bolt. With Wake of Vultures active from a Blazing elite kill, every Tesla bolt ignites enemies hit. Glacial elite power slows all Tesla targets. Overloading power shields them briefly (minor). The Tesla Coil fires constantly at up to 18 targets per half second during active periods, spreading these effects across the entire nearby enemy group instantly.
57 Leaf Clover improves proc chains from Tesla bolt hits. Tesla bolts have 0.3 proc coefficient. With Clover re-rolling failed procs for favorable outcomes, Ukulele, bleed, and on-hit items trigger more reliably from each bolt. On a survivor with high enemy density contact, Tesla + Clover creates a reliable cascade of on-hit effects across entire rooms.
Shatterspleen + Tesla on melee survivors creates group bleed explosions. At 100% crit, Shatterspleen bleeds every enemy hit. Tesla bolts hit up to 18 targets per 0.5s at 0.3 proc coefficient, generating bleed stacks across groups. Each bleed stack that reaches the HP threshold triggers a crit explosion hitting nearby enemies. Dense enemy groups become chain-exploding with enough Shatterspleen stacks.Unstable Tesla Coil is a red legendary item that periodically fires bouncing lightning at nearby enemies. While active, it strikes up to 3 targets every 0.5 seconds within a 35m radius, dealing 200% base damage per bolt with a 0.3 proc coefficient. The item cycles between 10 seconds active and 10 seconds off, giving 50% uptime. Lightning ignores terrain. Stacking adds 2 more targets per stack but does not increase damage or fire rate.
The on/off cycle is the item's built-in drawback as a legendary. It is active for 10 seconds then inactive for 10 seconds, cycling throughout the run. There is no way to prevent the off period or extend the active window. Brainstalks does not affect it since Tesla Coil is a passive item effect, not an activated skill. The 50% uptime is accounted for in the item's high damage output when active.
Yes. Each additional stack adds 2 more bounce targets per bolt. At 1 stack you hit 3 targets, at 2 stacks 5 targets, at 3 stacks 7 targets. Damage per bolt stays at 200% and fire rate stays at every 0.5 seconds. Stacking is most valuable in large enemy groups where extra targets are always available. Against single bosses, additional stacks provide no benefit.
Melee survivors that stay close to enemy groups get the most value. Loader is the best match - her grapple keeps her inside the 35m radius and her high single-target damage means Tesla handles AoE while she handles the main target. Mercenary similarly benefits from always being at melee range. Ranged survivors like Huntress who kite away from enemies frequently exit the 35m radius and miss out on significant uptime.
Complete the Macho challenge by dealing 5000 damage in a single hit. Loader's Charged Gauntlet on a boss at Stage 3 or later is the most reliable method. Railgunner on a weakpoint also works. Shaped Glass doubles base damage and makes the threshold easier to reach. The challenge counts any single damage instance, including equipment damage.
