[RPG] Can a psyker mask their presence

If you are the guy with the temptation to go for the easy joke, this may be extraordinarily difficult, since as GM you really have the opportunity to set the tone.

Maybe you need operant conditioning. Every time you go for the easy joke, throw a token in a jar that the players can use as a bonus of some kind. Make them the arbiters, so they are both watching for you to slip up and tacitly monitoring their own behavior.

Maybe you need a way to express this stuff directly. Sometimes playing an inherently over-the-top setting absolutely straight is just not viable, and injecting a little appropriate recognition of the absurdity is both a relief and helps maintain focus. Maybe have a comic relief NPC, a guy who recognizes the ridiculousness, a sort of court jester, and use that guy as your mouthpiece for that stuff.

There's been some important errata to how psy powers work, which is good, because the book's rules are actually somewhere between "unclear" and "contradictory" in several areas.

The most important thing to know is that the example is wrong, wrong, wrong, and should be wholesale disregarded.

The other important thing to know is that all Focus Power tests are made at a difficulty of Challenging (+0).

Also, note that you get +5 to your Focus Power test per point of effective Psy Rating - "effective" meaning "including modifiers for Fettered or Push". (Push provides +3 Psy Rating, and thus +15 to your check.)
