Cogwheel, Throwing Knife and Tesla Coil build

Build summary

Cogwheel connects Throwing Knife and Tesla Coil so a timed activation calls the other marked attack once per chain.

• Trigger chain
• Solo
• Normal

Core equipment

Cogwheel + Throwing Knife + Tesla Coil

Placement

Cogwheel must mark both triggerable attacks.

Requirements

Three defining pieces; retain a direct weapon while assembling them.

Fallback

Use Knife and Coil independently before Cogwheel appears.

Strengths

• Both attacks function before the full chain is assembled.
• One activation can call the other eligible marked attack.

Weaknesses

• Each item fires once per chain, preventing unlimited recursion.
• Tesla’s even-electric condition is separate from trigger eligibility.

When to pick it

You have multiple eligible triggerable attacks in the bag.

When to skip it

Fitting Cogwheel would remove the support keeping your main weapon useful.

Priorities

1. Keep Pistol or another direct damage source.
2. Mark Knife and Coil with Cogwheel.
3. Check both connections after merges or rearrangement.

CogwheelTesla CoilPistolThrowing Knife

Use Cogwheel, Throwing Knife and Tesla Coil. Cogwheel must mark both attacks. When one marked item activates, the other eligible recipient activates too. Keep Pistol or another direct weapon while collecting the three pieces.

Throwing Knife and Tesla Coil can attack on their own timers before Cogwheel appears. That makes each a usable step toward the setup while you search for the final piece.

Cogwheel positioning

Select Cogwheel and confirm that Throwing Knife and Tesla Coil are both in its marked set. Recheck after merging a chain member or adding bag space. Ordinary gun support should still reach the Pistol or its replacement.

Each item acts once within a chain. The timers can start later chains, but the linked activations do not recurse indefinitely. A passive item cannot replace one of the triggerable attacks.

Tesla Coil’s extra bounces require an even number of marked electric items. Cogwheel linking two attacks does not establish that this second condition is met. Inspect the Coil’s own selector and count its eligible recipients separately.

Missing chain items

Use the attacks independently until Cogwheel can mark both. Don’t remove the gun carrying the run simply to force a three-item arrangement into the bag. If one piece is missing, another upgrade to the working weapon may do more for the next map.

On later maps and bosses, keep direct damage for targets the timed attacks do not clear quickly enough. Add another triggerable item only when its action helps and Cogwheel can reach it. Movement still matters between activations.
