Build a Base RNG Progression Guide

Move from your first working defense to a repeatable progression loop. This route uses observed failures, layered placement, cautious upgrades, Boss Waves, relic crafting, and offline fighting without inventing level gates or rates.

Quick answer

The short version

First make one defense contribute, then add front and middle coverage, test a different role at the first leak, and change only one upgrade at a time. After the base is stable, use a boss run and an offline session as separate progression checks.

Walkthrough

Follow one controlled test at a time

Changing one variable makes it easier to understand why the base improved or failed.

  1. 1

    Finish the first full loop

    Roll one defense, place it where it can affect the approach, defend a wave, and note the first leak. That observation becomes the baseline for every later choice.

  2. 2

    Build two useful layers

    Keep front coverage at first contact and add middle pressure for survivors. Do not crowd every defense into the same opening point.

  3. 3

    Add a different job

    If the same visual defense role keeps failing at one point, test a different-looking role or position. Treat the result as a placement experiment, not proof of an unpublished class bonus.

  4. 4

    Choose one upgrade focus

    Use the first failure to decide whether to test layout, Damage, or Luck. Repeat the same wave before changing a second variable so you can tell what helped.

  5. 5

    Branch into advanced systems

    Run a Boss Waves baseline, inspect relic and crafting screens in-game, and compare an offline session with a before-and-after note. Exact boss drops, recipes, caps, and offline rates are not published here.

If you are stuck

Diagnose the first failure

The base fails immediately

Return to first contact and check whether the opening defense contributes to the actual lane before rolling or upgrading again.

More rolls do not improve the run

Stop comparing names alone. Place one result into the weakest layer and repeat the same wave.

You reached bosses but cannot compare attempts

Keep one fixed layout as the boss baseline and record the first attack or lane point that changes the result.

Common mistakes

Avoid misleading tests

Changing layout and upgrades together

A better result will not tell you which change mattered. Test one variable per repeat.

Treating a rare-looking roll as automatic progress

Its job still depends on where it contributes to your current lane.

Assuming community numbers are official

Odds, pity, level gates, recipes, and reward rates should be checked in-game until the creator publishes them.

FAQ

Questions players ask

What is the best progression order in Build a base RNG?

Use the first loop, establish two coverage layers, test a different role, make one controlled upgrade, then branch into Boss Waves, relic crafting, and offline fighting.

Should I prioritize Luck or Damage?

Watch the first failure. Test Damage when covered enemies survive pressure; test layout first when enemies pass an uncovered area. Luck can be tested separately when the base already uses its current rolls well.

When should I start Boss Waves?

Once the base has at least two contributing layers, run a baseline. The goal of the first attempt is to find the failure point, not to assume a required stat threshold.

Are relic recipes and progression gates confirmed?

The official description confirms boss relics and crafting, but complete recipes, quantities, and gates were not published in the references checked on July 15, 2026.
