Starfield:Stealth

Stealth is a novice tier physical skill that 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 ever, as it also unlocks the stealth meter. Without this skill, you will not know have a readily apparent gauge to how close you are to being detected.

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.
