The Rule That Saves the Most Resources
Do not try to build every character at once. Select one damage dealer, two compatible supports and one sustain. Raise that group together until it can clear story and farming stages consistently. A second team becomes important later for modes such as Memory of Chaos and Pure Fiction.
Character level, Light Cone level and important Traces are guaranteed improvements. Relic substats are random. This is why early Trailblaze Power should favor guaranteed progression before extended Cavern of Corrosion farming.
