Which upgrade should you choose next?

Use this general decision checklist with the options currently on your screen. It is not a tested Nebulous build ranking.

01 // GOAL

Decide what is stopping your run

Are you losing before reaching the core, or struggling to finish the fight? Choose a clear problem before comparing options.

02 // DESCRIPTION

Read the option in your game

Use the exact description shown now. Only count an effect as a benefit if the description actually says it provides that effect.

03 // COST

Compare what the screen shows

If costs or levels are displayed, compare them alongside the description. Do not assume a similarly named upgrade in an old guide has the same values.

04 // NEXT RUN

Check whether the choice helped

After the next fight, ask whether the same problem remains. Keep that result in mind before spending again.

Upgrade questions

Are there only six upgrades?: No. The official listing advertises 90+ Campaign upgrades; the six above are examples it named earlier.
Are Endless cards the same as upgrades?: The listing describes them separately: 90+ upgrades in Campaign, 250+ cards drafted between Endless waves. Card effects are not published.
Which game pass is most useful?: It depends on your problem. Additional Damage (+20%, 149 R$) is the cheapest stat pass; More Resources (+25%, 179 R$) targets upgrade speed; how it combines with the free +15% group bonus is not published.
What is the best upgrade?: A current, tested ranking is not available here. Compare your run's problem with the descriptions of the choices you can actually select.
Do these upgrades stack?: Stacking rules and exact values have not been verified here. Do not assume repeated selections multiply an effect.
Should I try a new build in permadeath?: Consider the risk first: the official rules say death deletes the save. Read the permadeath rules before choosing that mode.
