Starfield:Stealth

Stealth is automatically unlocked and can already be learned by using a skill point to learn it. Stealth makes you harder to detect when sneaking, and also increases the damage of suppressed weapons. It is highly encouraged you take this skill if you ever intend to do anything stealth-based, as it also unlocks the stealth meter. Without this skill, you will not have a readily apparent gauge to know how close you are to being detected.

Backgrounds
This skill is automatically learned with the following backgrounds:
 * Cyber Runner
 * Ronin

Skill Increases
By simply starting combat by sneaking and performing an attack before you are detected, you can make steady progress through this skill without any upfront investment into gear to help you hide.
