How to get boss materials in NTE?

This boss-materials page is more useful when it explains **how to judge which character should receive this scarce resource first** instead of stopping at a generic 'prioritize your core units' line. For current players, the practical question is usually which character is actually blocking your progression, appears in your main team most often, and gains immediate value from the next breakthrough.

A safer way to handle boss materials is:

1. Feed them first to characters who are already active in your main team and can use the upgrade right away

2. If two characters both matter, check who is closer to a meaningful breakpoint instead of splitting the resource evenly

3. Event, shop, and domain sources should be evaluated against your weekly stamina and account pressure rather than farmed in one fixed order every time

So this page now focuses on boss-material sources and allocation logic instead of treating one universal priority rule as the answer.
