At ECL 12 you get a lesser version of dominate monster, which is normally a 9th level spell. And what's nice about getting it at ECL 12 is that it comes online before mindblank is widely available and while there's some good monsters that aren't immune to mind affecting abilities. You'll want a 14 int to help meet the skill requirements.
