No stats, damage numbers, or tier rankings are documented in any reliable source, so none appear here. Official patch notes give the names; nothing gives the numbers.
The upgrade path
- Acquire the weapon at Epic grade with S-Grade Weapon Keys.
- Upgrade it through synthesis. Both the signature skill’s performance and its visual effects improve with grade.
- The top grade is Eternal, and crafting it requires materials that only drop from Boss Raid.
Below S-grade (what is actually verified)
- Six weapon classes exist: Dagger, Sword, Blunt, Crossbow, Gun, Staff.
- Weapons below S-grade use color-coded rarity tiers. A player review mentions a red tier; the full rarity ladder is not reliably documented.
- Weapon forging (leveling) exists, and forge level 6 is cited as part of at least one map-unlock requirement.
- Costumes are separate from weapons and grant stats that grow with costume level.
Watch out for
- Eternal grade is gated behind Boss Raid entry tickets, so your weapon ceiling is tied to how often you can run the mode.
- Swapping between weapon classes changes the flow of combat, per the store description. Nothing reliable documents a best class, so pick by feel.
