Use this general decision checklist with the options currently on your screen. It is not a tested Nebulous build ranking.
Are you losing before reaching the core, or struggling to finish the fight? Choose a clear problem before comparing options.
Use the exact description shown now. Only count an effect as a benefit if the description actually says it provides that effect.
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.
After the next fight, ask whether the same problem remains. Keep that result in mind before spending again.
Use the beginner checklist before trying to optimize a build.
