Currently, every point of Resolve above 10 provides -3% hostile effect duration (up to a maximum of -75% at 35 Resolve). There's also a ring which gives -35%. Do these stack additively, i.e. is it possible to reach -100% hostile effect duration? And if so, does this make you immune to all afflictions? I have to admit, the idea of shrugging off Charm and Stun like they were nothing holds a certain appeal to me.
What specifically counts as a hostile effect? Only afflictions or damage over time effects as well? What about things like drug crash penalties, the Berserker's confusion during Frenzy or the Priest's Incarnate debuff?
