In the Deathwatch Core Rule book, the paragraph describing Focus Power Test states:
A Focus Power test is a Willpower Test that determines whether a functions successful. The amount of time it takes to make this test is determined by the power being used and may be a Free Action, Half Action, Full Action or Reaction. In most cases, passing a Focus Power Test simply means that the power has manifested, while failing the test means that it has not. However, degrees of success or failure may also play a part depending on the type and nature of the power being used. Many powers also indicate an Opposed Willpower Test, especially when used against an unwilling foe. In these cases, the Opposed Test is also the Focus Power Test, and even if the psyker scores better than his opponent but does not roll under his Willpower, the power will still fail. You may add a bonus to your Focus Power Test equal to 5 times the Psy Rating used for the power. A Focus Power roll of 91-00 always fails.
Does this apply to all Focus Power Tests, or just to opposed tests?
