Indeed. I was stating you didn't need to know which weapon because...
Stats can be your hime stats instead, or total atk.
Skills can be typed in.
Weapon type... yeah I concede. That does matter with the 10/20% stat buff (forgot which number it was) for your hime, or if you don't have the weapon type for a soul.
Rarity... is rarity.
Nothing much else for show IMO, which was why I was kinda against using weapon names.
That said, I think you might need to include a formula for the relic weapon skills, they operate on different multipliers, and maybe your union buddies have one.
