Resource management is not about saving everything forever. It is about spending enough power to keep progress efficient without entering the next fight depleted.
Use renewable options for routine encounters
Basic attacks and reusable abilities can handle easier situations while limited resources remain available.
Spend strong abilities when they meaningfully change the outcome
If a powerful action prevents major damage or ends a dangerous fight quickly, the cost may be justified.
Rest when key roles can no longer function well
If several party members have lost the resources that define their role, continuing may create more risk than value.
Review what actually ran out
After a difficult section, identify the resource that became the bottleneck and prepare around it next time.
