Interestingly, the same ogre sorcerers that have the more powerful variant of Astartian magic are also the only (to my knowledge) mortals to make any extensive use of that Astartian soul magic that Muttonhawk just mentioned.

It's part of what enables them to enslave djinn by force of will when other shamans simply cannot do that, and it's also been demonstrated to allow them to temporarily enhance their strength or agility to superhuman levels. There's some IC post where an ogre shaman named Dargok uses this to fight off a bunch of urtelem.
