Probably a dumb one, but the wording on things are weird in this game.
I guess the legendary truly only procs when you have your fiend out. It doesnt summon your fiend to do this attack? So 15ish seconds every 3 minutes? (I do see with mindbender its 1 minute cooldown. So up 17 seconds every minute. I use void torrent typically)
Kinda confused why guides can say this is a better lego. Currently running Talbards.
Just making sure i am reading it right
