Starfield Skills and Skill Trees explained

Starfield has 82 Skills in total spread across five different Skill Trees - Physical, Social, Combat, Science, and Tech.

Each Skill Tree is focused around a specific type of Skill. The Social Skill Tree, for example, allows you to unlock Skills like Persuasions and Intimidation which grant you more options when interacting with NPCs. Meanwhile, investing in the Combat Skill Tree can improve your capabilities with the various weapon types, such as Rifles, you can use in Starfield.

Each Skill Tree is also divided into four tiers, such as Advanced (second tier) and Expert (third tier). To access these tiers and their associated skills, you need to invest a certain number of Skill Points into a Skill Tree. This means that if you fancy being able to mind control creatures, for example, you need to invest enough Skill Points into the Social Skill Tree so you can access the Xenosociology skill on the highest tier.

Each Background for your character also comes with three Skills automatically unlocked, with said Skills being themed around the Background itself. The Diplomat Background, for example, begins with the Persuasion, Commerce and Wellness Skills since it's a role initially focused around communication. As you progress through Starfield, you'll be able to customise these Backgrounds by unlocking new skills.

Starfield Skill Ranks: How to unlock and level up a Skill in Starfield

You receive one Skill Point every time you level up in Starfield. This Skill Point can then either be used to unlock a new Skill or invested into one you already have, so you can level up that Skill.

To properly level up a Skill, and in doing so increase its ranking, you must spend one Skill Point and complete a Rank Challenge.There are four Ranks in total for every Skill and increasing a Skill's Rank will unlock more bonuses for said Skill.

The Rank Challenges are themed around the Skill itself, you can naturally complete them as you play Starfield, and become increasingly difficult as you progress to higher Ranks. The Rank 1 challenge for the Security Skill, for example, is 'Pick 5 locks' and then, for Rank 2, it becomes 'Pick 15 locks.'
