Base Abilities

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. Technically there is no maximum, but ability point bonuses acquired from equipment and consumables are limited to 10 points. The highest ability score you can theoretically achieve is thus 28.

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%.
