A first character is not ruined because you tested the wrong weapon. The mistakes that repeatedly cost time are easier to name: treating Legend as a normal switchable mode, trying to parry yellow attacks, ignoring the Qi and Execute loop, optimizing random gear before choosing a Martial Art, skipping Wayfarers and Boundary Stones, taking preventable fall injuries, and waiting in real time for a normal quest clock gate.

Optimizing before choosing a Martial Art
Do not pick Legend only because it is missable. It is available only during character creation; lowering it is allowed, but returning to Legend is not. Choose it for the challenge and identifiers, not from fear of an incomplete checklist.
