2 x 2.5 = 5

In any event, it is still possible to get an "infinite" duration if you always have something to attack, but that's not generally going to happen.

Minimum duration is 17 seconds (it is only lost each second I believe), and will generally be extended by the passive, but will usually not get to 100 seconds or anything like that due to killing your attack target(s).
