How to upgrade weapons in NTE?

This weapon-upgrade page is more useful when it explains **when to keep pushing one weapon higher and when to stop and protect resources for the rest of the team** instead of repeating 'max your main weapon first' as a blanket rule. For current players, the more useful judgment is whether the weapon is truly attached to a long-term main unit, whether the next ascension gives a real breakpoint, and whether you are over-investing in a temporary weapon.

A safer way to think about weapon upgrades is:

1. Upgrade the weapons that are already locked into long-term use and give immediate gains in damage, rotation feel, or consistency

2. If the character is still in a temporary slot, avoid sinking too many materials into a weapon that may soon be replaced

3. Higher rarity alone does not automatically make a weapon first priority; what matters is whether it actually belongs to your current core team plan

So this page now focuses on how weapon upgrades and ascensions work, plus how to judge investment timing, instead of preserving one universal upgrade order.
