What the Official Listing Says
The official Steam page says players can wield over thirty weapons and mix and match more than twenty Phantom Edges. It also explains that defeating powerful foes can award their weapons and signature techniques.
Weapons vs. Phantom Edges
Weapons form the main arsenal and carry fighting techniques. Phantom Edges are a separate group of tools that can be combined with the player's chosen style. The exact categories, upgrade paths, and duplicate rules still need in-game verification.
What the Wiki Will Track
The weapon database will list acquisition source, moves, role, upgrades, and boss matchups for each verified weapon. The Phantom Edge hub will cover effects and pairings without counting unconfirmed trailer appearances as separate items.
