Sub weapon

"Divert the enemy with weapons like Splat Bombs or the Sprinkler. Pro tip: You can try out the weapons at Ammo Knights before you buy."

- Splatoon's official website

The sub weapon is a secondary weapon in Splatoon and Splatoon 2. They use up considerably more ink than a main weapon, and as such, usually serve specialized purposes limited to specific combat situations and are not often used as a main method of inking the environment.

Usage
Sub weapons are deployed by pressing the R button. If the sub weapon is throwable, holding down the R button will display a trajectory to help the player aim the weapon. If the sub weapon is not throwable, it will be placed on the ground.

Sub weapons consume a great deal of ink, so it may be necessary to monitor the ink supply before and after deployment of a sub weapon. When the ink supply becomes sufficient for using a sub weapon, a sound effect will play and a red light will show on the ink tank.

Sets
Sub weapons come in sets with main weapons. These lists show which sub weapons come with each main weapon.
