Tesla Coil’s even-item rule

How the combination works

Tesla Coil's additional bounces require an even number of marked electric items. Count eligible recipients inside its selector, then recount after merging, rotating or moving equipment in either backpack.

  • Tesla Coil
  • Electric
  • Even item count
  • Marked cells
Bonus condition
The marked electric-item count must be even.
What counts
Eligible electric items inside the selector, not empty cells or every electric item elsewhere in the bag.
Merge risk
Two recipients becoming one can change an even count into an odd one.
Co-op risk
A partner moving a contributing recipient can remove the bonus without a change in your bag.

Priorities

  1. Count the marked eligible recipients before adding more electric equipment.
  2. Recount after a merge or rotation rather than assuming the old bonus survived.
  3. Review the shared edge when either co-op player changes a recipient.
  4. Compare the bounce bonus with the equipment you would have to displace to restore an even count.

Useful equipment and guides

Tesla Coil’s extra-bounce effect needs an even number of marked electric items. Count eligible items inside its selector, rather than every electric item in the bag.

An empty marked cell does not supply an item. Neither does a nearby support qualify merely because it looks electrical.

Merging and moving electric items

Merging two recipients leaves one. Rotating an item can move it outside the marks. Either change can turn an even set into an odd one.

Recount after rearranging, then confirm the bonus before leaving the bag. Avoid giving space to an unwanted item solely to reach an assumed bounce value.

Version 1.0 lets selectors reach across backpacks. If the other player’s electric item contributes to the count, moving it can remove your bonus. Review the shared edge after either player merges or replaces equipment.
