Perks:

Perks are optional hero upgrades in Overwatch 2 that modify a hero’s abilities or passive effects during a match. They are used to add a layer of progression and customization, letting players adapt a hero’s playstyle as the game goes on.

Perks matter because they can change how a hero is played in a given match, affecting decisions such as when to take fights, how to engage, or which ability interactions to prioritize.
