Feed Amplifier a buff and keep recipients beside it
Amplifier forwards buffs it receives to eligible plots directly beside it, reaching one adjacent plot at level 1 and up to three at level 3. Put it next to a Forest or Blacksmith and the troop you want to strengthen, then upgrade it before the yearly support effect triggers.
How upgrades change adjacent coverage
Choose Amplifier's position for both the incoming buff and the plots you want to receive it. Its level controls how many adjacent recipients it can reach, so a crowded cluster does not automatically get full coverage. Use the affected-plot highlights during placement to check which plots the position will serve.
| Amplifier level | Recipient coverage |
|---|---|
| At level 1 | Forwards received buffs to one adjacent plot. |
| With each additional level | Can forward the received buff to one additional adjacent plot. |
| At level 3 | Can reach up to three adjacent recipients. |
Upgrading improves recipient coverage; you still need a buff coming into Amplifier. Keep both parts of the layout in mind when spending an upgrade: the source that feeds it and the neighbours that benefit. Check the highlights again before relying on the wider coverage.
Set up a Forest or Blacksmith relay
Use a Forest when you want HP growth, or a Blacksmith when you want damage growth. Both offer a concrete way to feed Amplifier through an adjacent support building. The arrangement below uses Forest; Blacksmith can occupy the same support position for a damage-focused setup.
- Place Amplifier where the intended troop can sit directly beside it. This establishes the position from which the incoming buff can be forwarded.
- Place a Forest beside Amplifier. Its yearly HP buff supplies the effect that Amplifier will pass onward.
- Place the troop you want to strengthen beside Amplifier. It is now adjacent, but must also fall within Amplifier's recipient coverage.
- Inspect the affected-plot highlights during placement. Check that the intended recipient is covered before relying on the relay.
- Upgrade Amplifier before the annual support-building effect triggers. The upgrade expands the adjacent recipient coverage for that incoming buff.
- Let the yearly Forest effect trigger with the layout in place. Forest buffs Amplifier, which forwards the received buff to its eligible adjacent recipients.
Use Wise to feed an Amplifier ring
Wise supplies a yearly stat buff that Amplifier can forward. A plot beside two Amplifiers can receive that buff three times: once directly and once from each Amplifier, provided both cover it. Check the recipients before building around that interaction, especially while the Amplifiers are still at a low level.
For a King of Time ring, Amplifier, Orbiter, Portal and Hourglass are all in the starting deck. Put Orbiters and Portals beside the Amplifiers first, then bring in Hourglass once the Orbiters can survive the opening clash. Give Hourglass Amplifiers on the sides you can spare so it receives the outside support the layout is built to provide.
Why a setup may pass on nothing
- No incoming buff: establish a buff source before expecting Amplifier to improve nearby troops. An Amplifier that receives no buff has nothing to forward.
- Too many intended recipients: a level-1 Amplifier reaches one adjacent plot. Check the highlights rather than treating every neighbouring plot as covered.
- Recipients too far away: put the troop against Amplifier itself. A distant plot does not receive its forwarded buffs simply because it belongs to the same build.
- Expecting an entire card or event to repeat: build around the buff Amplifier receives. Its forwarding rule does not promise unconditional duplication of every card or event.
Keep older layouts and patch behaviour separate
The PC full release arrived on November 12, 2026. When copying an older Early Access layout, use the current affected-plot highlights instead of assuming identical coverage. Patch 31 added those Amplifier placement highlights, making them useful for checking the board in front of you.
The patch notes also record fixes for Mangler–Amplifier interactions and for troops freezing when King of Time used Wise with Amplifiers. Keep those fixes in mind when following an older demonstration of either setup. The developers also advise starting a new run after installing the release patch, since an existing run does not store its updates.
