Subclass

A focus is a player class-specific, upgradeable, and interchangeable bundle of abilities and characteristics used by Guardians in Destiny.

Overview
Focuses are the primary method by which players upgrade and improve their characters. Each focus is a bundle containing a selection of specific grenade types, movement abilities, melee bonuses, weapon specialties, passive abilities, and upgrades to abilities.

Focuses are Player Class-specific. A player can acquire multiple focuses for a single character, and focuses may be switched by the player at will. Focuses earn XP just like weapons and armor, allowing them to be customized and upgraded according to the player's choice.

As the player earns XP, they may upgrade their focus from level 1 to 20, and selected upgrade trees affect what upgrades and abilities are available further down the line. Players may find that different focuses are useful for different scenarios.

Although some weapons and armor may be more effective while using a particular focus, particular focuses do not require a player to use specific weapons or armor.

Design and Inspiration
Focuses are designed to allow players to become more attached to their characters without becoming bored. Thus, players can have a single character that is equally useful in competitive multiplayer or a cooperative Raid simply by switching focuses. Additionally, the ability to switch out weapons and armor regardless of focus provides players the opportunity to further tailor their build for particular situations.
