Nerd Stuff
Nerd Stuff supports hacking computers and robots at increasing difficulty thresholds, and has three named perk unlocks.
How it works
The table lists Hack Computers and Hack Robots, each from difficulty 1 to 10 or less. It names Targeting Override at level 3, Electric Leakage at 5, and Overclock at 7. The guide says Nerd Stuff can turn hostile robots to your side, but the supplied passages do not describe the named perks or specify effects for particular hacking checks.
Read the supporting references
A source-bounded reference to eleven named Ranger skills and their described effects, difficulty thresholds, and listed perk unlocks. It covers combat, general, and exploration skills; it does not rank effectiveness or provide a complete build guide. Guidance explains the referenced mechanics; it is not a tested damage ranking. Check the stated edition and source version before applying a patch-specific detail.
