I was going through Arsenal, and I ran into the Focus Will maneuver. It says that you gain +2 dice on willpower tests. Now, ordinarily, I would think that would be any test that used just Willpower ... but SR4 doesn't have 'willpower tests' using only willpower. Then I thought they meant attacks of will ... but they don't say 'attacks of will', nor does the errata change Focus Will.
The more I look at it, the more I tend to lean towards 'Willpower tests' meaning any time you use willpower in a test. Which has several implications.
So, what *is* a willpower test? Thoughts, opinions, official rulings? (I might even except a rant, if it answers the question. )
