Wasteland 2: Director's Cut · Equipment bonus
Skill trinkets
Some skill-specific trinkets reportedly add one to three levels, but these bonus levels do not unlock perks for that skill.
How it works
The discussion reports trinkets that add +1 to +3 levels. These can contribute to a skill's level, but the participant explicitly says they do not unlock that skill's perks. Alarm Disarm and Brute Force are named as skills without trinkets. The source does not list which trinkets correspond to other skills.
