Starfinder Themeless Character Theme
Modifier: +1 to any 1 ability
If you decide that none of the themes fit your particular character concept, you can choose not to have a theme. You then gain the following benefits at the listed levels. A themeless character is considerably less powerful than a character with a theme, so choose this option with care.
General Knowledge (1st)
You gain a class skill of your choice when you create a themeless character. Also, you gain an ability adjustment of +1 to any ability score you choose.
Once per day before you roll a skill check, you can gain a +2 bonus to that skill for that check.
Extensive Studies (12th)
Choose a skill that is a class skill for you. Once per day, you can reroll one such skill check before learning the results of the roll. You must take the second result, even if it is worse.
Steely Determination (18th)
Increase your pool of Resolve Points by 1.
