Check the live reroll screen before you commit
The safest reroll plan starts with the current in-game interface. Find the reroll or character option, read what it says will change, and only then decide whether the result fits the build or fighting style you want to play.
Do not treat a community post, a video, or a public code roundup as proof of a permanent reroll rule. These sources can help you find the right question, but the game's live confirmation screen is the best place to check the current action and requirement.
If you are unsure what to keep, pause before rolling again. Compare your current option with the fighting-style notes and consider the role you want to practice. This avoids turning a useful result into a blind repeat attempt.
