How does the Arc Disc system work in NTE? Disc acquisition and upgrade guide

This Arc Disc page is more useful when it explains **whether you should treat discs as a long-term endgame filter or first use workable transitional pieces to stabilize your current team** instead of compressing everything into one rigid growth script. For current players, the practical priority is usually to get usable discs online first, then worry about rarity ceilings, perfect substats, and final endgame pieces.

A safer way to think about Arc Discs is:

1. Give your regular main units functional discs first, then refine stat quality later

2. High rarity and high ceiling matter, but that does not mean early progression should stall for one ideal drop

3. Farming sources, upgrade order, and stat preferences should all be read through the lens of your actual active team rather than copied from one universal route

So this page now focuses on Arc Disc acquisition, transition use, and filtering logic instead of preserving one early-version priority order as the long-term answer.
