if you free their thralls early on you can use their nacklace things to put round their heads and just control one and have him on yours..you only get a few of these...and it is SOA or TOB where you get the blue vials which when you drink it essentially casts chaotic commands on you..you get the vials in the illithid dungeon on either underdark of TOB, they are handy.
