Effect
- At battle start: all weapons in the backpack gain +1 damage
- Applies to all weapons. Dual-wielding buffs both at once
- Only weapon-type items qualify (accessories / food / gems are excluded)
The +1 damage multiplies per hit. A weapon attacking every 1.5s accumulates +20 damage in 30 seconds; a high-speed weapon (daggers at 0.8s) returns +37 or more in net damage. Builds with higher attack count see exponentially growing DPS contribution.
Evaluation & Analysis
Whetstone is a Neutral accessory that permanently grants +1 damage to every weapon for 4G, ranking at the top in both solo performance and crafting-hub value. Because Backpack Battles multiplies "1 damage" by attack count, a single Whetstone produces 50-150 cumulative damage per match — equivalent to one additional buff weapon's worth of contribution. Equippable by every class at 1-slot size, it is a near-mandatory foundation accessory for any weapon-focused build.
Crafting-material value far exceeds solo performance. Whetstone connects to six powerful recipes, each leading to a different build finale.
- Heroic Sword (Wooden Sword + Whetstone x2): A top-tier generic sword for early game
- Heroic Longsword (Heroic Sword + Whetstone): Upgrade of Heroic Sword
- Heroic Shield (Wooden Buckler + Whetstone): Shield that combines damage +1 with defense
- Katana (Whetstone + specific materials): High-speed slashing weapon
- Flame Sword (Whetstone + specific materials): Fire-element sword
- Shepherd's Crook (Whetstone + Broom): Pet activation speed +
