Subtlety
From Starsonata Wiki
Subtlety is a skill found in Bipolar on the base Black Precipice and costs 25 skill points per level, with a max level of 10.
"Your attacks are painless and AIs will tend to ignore them, -1% hostility."
This makes your shots generate less hostility towards AI, a particularly good skill for shield monkeys and snipers.
You cannot have 1 or higher in despicable, the polar opposite (pun intended) of subtlety, which makes you generate more aggression from AI enemies.
