I was wondering how this actually works.
Focus Power: is a Difficult (-10) Opposed Willpower Test
Then it says: The psyker may nominate a single target within range and line of sight, who may resist with a Willpower test......................
Does that happen after the Opposed Willpower Test or is that the Opposed Willpower Test? I´m just asking, because in a way both options seem plausible.
I mean, an opposed WP test (even with the +20 WP) is pretty much no defense vs a psyker, who just might compel you to kill yourself .
Adding to that, it´s also very cheap in terms of XP.
EDIT: Alright, I don´t believe in it anymore, pretty much every spell with an opposed test, has the same sentence in it. So the opposed test is the resist I guess (bit of joke imo). One could argue that the opposed test is akin to a "to hit" roll (the psyker worming his way into the other ones mind), while a seperate WP is the "evasion", but I don´t think so.
