Base Ability Scores in Underrail serve as the base for your character and consist of seven attributes: Strength, Dexterity, Agility, Constitution, Perception, Will and Intelligence. Certain functions, items and actions require a minimum score of a certain base ability to be used or performed, while some items, such as foods, temporarily boost them. Some feats also require a minimum score of a certain base ability (and skill level) to be picked and used. Each base ability is set to a default of 5 and has a minimum of 3 and maximum of 10 during character creation.

In the base game, you gain a base ability point every 4 levels. No base points are gained on Veteran levels, but veterans may choose an Increased Base Ability feat. Minimum base ability score is 1 and maximum is 20.

Level 4 8 12 16 20 24
Cumulative base points 1 2 3 4 5 6

Base abilities directly boost related skills by a certain number. An ability score of 4 is the breakpoint where related skills receive no bonus nor penalty from the ability score.[1]

Every point in base ability above 4 increases the effective value of dependent skills by 8.5%, while every point below 4 decreases it by 10%.
