The implication, as I understand it (and someone correct me if I misread it) is that the effect is amplified  for the selected group, but reduced for everything else. So, your healing (or other positive effect) would be increased by 50%, but non-dwarf targets would see a cut by half... so harming undead would be 1/2 of it's normal effect, unless the undead happen to be dwarves.<br/><br/>Is that right Muse?
