Weapon mechanics (applies to every P5X weapon)
Weapons are hard-locked to one character — they cannot be swapped to another character.
Weapon level is SHARED: leveling up any one weapon raises the level of every other weapon owned by that same character, regardless of rarity. Level cap is 80, reached via 7 breach overclocks using crystals (Blue/Purple/Yellow).
Forging is NOT shared — each weapon forges independently. Even-numbered forge steps (0/2/4/6) need a duplicate of the exact same weapon; odd-numbered steps (1/3/5) accept any weapon of the same rarity.

Is Ephemerality worth upgrading?
Weapon level is shared with every weapon owned by the same character (no extra cost there), but forging is per-weapon — worth it mainly if you actively use this character.
