Quick answer: learn the lobby, commit to one base class, unlock one reliable subclass, complete stable routes, and only then optimize Prestige and optional event builds.
Stage 1: Learn the lobby
Find class selection, Boons, party setup, inventory, and the Skill Tree before starting.
Stage 2: Finish a repeatable early route
Focus-fire enemies, spend points promptly, and learn when an encounter is optional.
Stage 3: Unlock one subclass
Choose a path that supports the base class role instead of collecting unlocks at random.
Stage 4: Learn crafting and Boss Souls
Use the Stash and Craft tab to turn run materials into an immediate route advantage.
Stage 5: Invest Prestige
Concentrate early permanent progress in the class you actually play, then branch out once normal clears are reliable.
