Skill

Skills are learned abilities of a character. The skill level shows how good the character is at that skill. Skill levels can be increased by allocating skill points earned from gaining levels. Skills can also be improved by reading specific books or completing quests within the games.

==Mechanics==
The success of an action can be determined by a skill check or a skill roll.
=== Skill check ===
A skill check is when the game checks if the character's skill meets a minimum skill value. For example, the Chosen One can download combat implant schematics with at least 51% in the Science skill and at least 75% in the Doctor skill.
===Skill roll===
A skill roll emulates the way skill rolls are done in traditional pen-and-paper RPGs. A skill roll is successful if a character's skill value is higher than a random generated number (1-100). In this simplified situation, a character's skill value is effectively a chance of success.
However, a skill roll typically has a modifier that adjusts the character's skill value for the purpose of the skill roll. A positive modifier makes an action easier (such as using a tool in a Repair skill roll) while a negative modifier makes an action harder (such as using Small guns in darkness). Some skill rolls use a predesignated system of modifiers (combat) while other skill rolls use modifiers specific that situation (a specific line of dialogue that requires a Speech skill roll).
Rolls are commonly used instead of skill checks for intrinsically random actions like combat, Lockpick, Steal, and avoiding random encounters.
Some skill rolls limit the success rate to a maximum of 95%. A few skill rolls can also generate critical successes and critical failures. For combat skills, the effect is determined by critical hit tables.
==Notes==
* In Fallout: Brotherhood of Steel, skills work like perks in other Fallout games.
* In Fallout 4, skills were replaced entirely by perks.
