Whetstone

A rare weapon from the Rock set that grants +1 Damage for the rest of the battle when used. Unlike most weapons, it doesn't attack — it's a stat stick that boosts your damage output permanently for the fight. Use it at the start of a battle for maximum benefit. The DNA Multiplier trinket doubles the effect to +2 Damage, since it doubles all status effects applied to the wearer.

The +1 Damage buff persists for the entire battle and applies to all attacks, making it a multiplier on every action taken that fight. Used at the start of a boss fight, it amplifies total output across every hit landed until the fight ends. The DNA Multiplier doubling it to +2 is a significant synergy — that's a consistent +2 to all damage for the whole fight from a single action.

Best used as a pre-fight or early-fight buff on high-attack-frequency cats where the +1 to all hits compounds across many attacks. Part of the Rock set for builds running multiple Rock items. The DNA Multiplier synergy makes this particularly attractive if you're running that trinket. A weapon slot investment that pays off more the longer and harder a fight runs.
