Ability chunk
Ability chunks are a currency in Splatoon 2. They can be acquired from 
Murch or as a reward from Salmon Run. They are used by Murch to add secondary abilities to gear.
Obtaining chunks
Ability chunks can be obtained from 
green capsules that are rewards in Salmon Run. Ordinary green capsules have a 40% chance to contain 2 abilty chuncks and a 10% to yield 4, while shiny green capsules guarantees 4 chunks. Gear rewards can also be exchanged for the abilities present on the given gear, turning those sub abilites into chunks.
Murch has the option to scrub any gear the player has, where the secondary abilities are "scrubbed" off and turned into chunks that the player obtains with the cost of 
20,000 cash or 2,000 cash exclusive to the 
Splatfest Tee. The player also gains chunks when rerolling gear, where the previous sub abilities are turned into chunks.
Adding abilities
Multiple chunks are required to add one of the secondary abilities to a piece of gear. For example, if the player is looking to add one secondary ability of Run Speed Up, they would need 10 Run Speed Up ability chunks. The amount of these chunks that are required rises, if the player wants to add an ability that matches the one already present as a sub on the selected gear.

Uses
Ability chunks are a more reliable method for acquiring sub abilities than re-rolling gear or using drinks from the Crust Bucket. As ability chunks are a reliable method for acquiring sub abilities, they are often used for stacking abilities or getting abilities that are unlikely to appear in a re-roll.
