You bought the legendary Baton of Aiden Pearce, making it 10 times better than usual.
(Just kidding, but its pretty good due to custom made modifications he installed)

Stats:
60 Damage (70 Charged) Well, getting hit in the face with a baton repeatedly quickly will knock you out. Or kill you.
100 Knockdown (140 charged)
30 concealment (same)
2 Second charge time
250 Range (same)
Faster swing speed because a baton is supposed to be used in quick hits (faster than pick axe)

Recent changes-
Fixed swing speed because I made a stupid mistake :/

Recommended with the Watch Dogs maskand Watch_Dogs inspired telescopic baton (this is for the telescopic baton)
