How to Save Energy for Rainbow Lumis in Lumi Master

For Rainbow Lumi progression in Lumi Master, focus energy spending on event nodes that advance milestones offering free energy, Starlit Leaves, or coins. The supplied material does not identify specific nodes or give their energy-to-resource rates, so it cannot establish which stage has the best return.

The video description says the strategy connects energy spending to milestone claims, then uses free energy to continue progressing. Before spending, check which event nodes count toward those milestones and what each milestone rewards. Avoid assuming that a particular stage is most efficient without its costs and rewards to compare.
