TL;DR: B-grade weapons are your core gear at mid levels (52-61). On low-rate servers they're the ceiling for many players, so the right Special Ability (SA) and a high enchant matter far more than the base weapon. Match the weapon to your class, then push the enchant to +7-+10.

Overview

B-grade weapons carry you through the mid game (levels 52-61). On low-rate servers this is the peak of practical gear for a large share of players, so getting it right pays off for a long time. The base weapon matters less than your enchant level and your chosen Special Ability (SA).

Weapon List

Here are the go-to B-grade weapons by type:

WeaponTypeBest for
Sword of MiraclesOne-handed swordTanks (with shield) and one-hand melee DD
Berserker BladeTwo-handed swordMelee DD chasing maximum P.Atk
Bow of PerilBowArchers - the only real B-grade choice
Demon's DaggerDaggerDaggers / assassin classes
Staff of Evil SpiritsMagic staffMages and nukers
Dragon GrinderFist weaponFist-fighter melee DD

How to Choose

When B-grade is your endgame, the enchant is critical. Push your weapon to +7-+10 - the gap between +0 and +10 is enormous. Then pick the SA that fits your playstyle: Focus for PvP (crit rate), Health for survivability, and Haste for fast farming.

A well-enchanted B-grade weapon at +10 can compete with a plain, unenchanted A-grade weapon - so invest in the enchant before you rush the next grade. For weapon-specific stats, see the Sword of Miracles and Demon's Dagger pages.
