Quick layout rule: use front, middle, and cleanup layers, mix defense roles, avoid placement mistakes, then test one change. Spacing, traps, mortars, and exact coordinates stay general because their full stats are not public.
Start with coverage where enemies enter your effective area, keep a second defense layer for survivors, and reserve a cleanup layer when pushing bosses. Mix visual defense roles only to test a gap—there is no confirmed hidden class synergy.
Changing one variable makes it easier to understand why the base improved or failed.
Watch where enemies first enter the area your current defenses can actually affect. Keep at least one defense contributing there instead of leaving the approach empty.
Tip: Use the same wave for every placement test.
Place another useful defense between first contact and the base. The goal is to keep pressure on enemies that survive the opening, not to copy an exact coordinate from another player's base.
For boss or higher-wave attempts, reserve a final layer for enemies that pass the main group. If nothing reaches the back, test whether that position can move forward without creating a leak.
If one repeated visual role keeps failing at the same point, test a different-looking role or placement. Do not assume an official synergy, element, or class bonus that has not been published.
Repeat the same wave or boss test and record whether the first leak moved later. Keep changes that improve the failure point; undo changes that make it earlier.
Strengthen or reposition front coverage, then repeat the same wave before replacing every defense.
Add middle or cleanup pressure and watch which survivors escape the main group.
Use one fixed layout as a baseline and record the first boss attack or lane point that causes the difference.
A dense opening can leave the rest of the lane uncovered after enemies pass it.
You will not know which change helped. Move or upgrade one thing before retesting.
Camera angle and unknown range make pixel-perfect coordinates unreliable.
The safest current pattern is layered front, middle, and cleanup coverage adjusted to the first point your own base leaks. There is no verified universal coordinate layout.
Use them where they contribute to an uncovered lane layer, then compare the same wave. Exact item ranges and optimal coordinates are not public.
Test at least one different visual role when a repeated setup fails at the same point, but do not assume unconfirmed class synergy.
Use at least two coverage layers, keep cleanup pressure, run a boss baseline, and change one failure point at a time.
