You invoke the fickle nature of the Warp to tilt probability in your favour. When you must make a Test, you can attempt to manifest this power immediately before making that Test. If you manifest it, you make the Test with Advantage. If you fail to manifest it, you make the Test with Disadvantage. This power cannot be used to augment Psychic Mastery Tests, and it cannot be used more than once per Round.
Specialisation in Divination applies to this power's Manifest Test.
