Mind Probe (3.5e Maneuver)

''I know all your secrets. To me, you're just a fool with a stupid robe and pointy cap. I'll strip you of your best spells and utterly break you!''

You concentrate intently on the foe and peer into his brain. When you do, you learn all of your opponent's variable abilities - feats, skill tricks, spells known or prepared, powers known, and maneuvers readied. For the rest of the encounter, whenever you use any effect on that opponent that would deprive him of one or more of these abilities, and he would normally be allowed to choose which ones to lose (for instance, a wizard choosing which spell slots are lost to a mind scrub attack), you make that choice instead.

Using this maneuver provokes attacks of opportunity and requires you to make a Concentration check if it is interrupted. A creature under the effects of mind blank is immune to this maneuver.
