Damage Up
From Inkipedia, the Splatoon wiki
Damage Up increases damage of your main, sub, and special weapons by upto 30%. However, weapons cannot pass their innate "number of hits to splat" threshold. For example, Aerospray MG has a base damage of 24.5, meaning that it takes five shots to splat at base. It cannot drop below this number, so Damage Up will cap its damage at 24.9, so it still takes vie shots to splat. Damage Up is most useful when using weapons with a high rate of fire or those on the lower threshold of the "number of hits to splat." This is ideal for countering opponents equipped with Defense Up.
