Nanaki's lightning attack managed to knock a leg off of one of the Grunts, but aside from that it didn't do much. So long as the other legs were there to move it toward its targets, it would keep moving. It was the minions with the guns that were more of an annoyance than the ones equipped with the swords and axes (though when they got close enough, they were just as annoying, too). So they were ones attacked first.

One of the Shrikes that managed to get inside swooped down, aiming for the minions with the guns. It sent a number of psychic lances down, trying to separate the group of them.
