Charm

This dark gift allowed Marcus to control the minds of humans (even violent ones). When Kain absorbs this gift he can only use it on non-violent hum.n While controling a human he can have them interact with switchs, levers, eta. but not weapons, and they could also cry for help, a feature if used properly would lure a violent human to oh say, a demon-bug in the canyons so they'll fight each other (less work for Kain) or to guide to Kain.
