This is probably more of a fluff than a hard rule question, but are Astropaths and Sanctioned Psykers supposed to keep their powers hidden from regular public and use them as scarcely as possible? Is there somewhere along their training/sanctioning the reinforced rule of not manifesting powers around ordinary folk?
As an Astropath, pretty much all I got going for me (at least at lower levels) is trying to Compel enemies or Deprive them of their senses for better crowd control. Since I start with Telepathy, I don't have any buffs or other "support" techniques. My Stub Auto is good in a pinch but can't reach Lasgun enemies and I have no melee skills whatsoever. Considering an encounter takes more than 3 rounds:
- Would it be acceptable for the psyker to try his best in the fight and use one useful action (aka: power) per Round? Is that perfectly normal for an Astropath trying to serve his Rogue Trader in the best way he can, or is it considered abusive from a psyker training point of view?
- Should the presence of "innocent" imperial citizens make a difference in power use in the case of an already started fight?
- Would using Fettered versus Unfettered/Pushed make any difference on any of the above? If yes, how can the Astropath determine when a situation is dire enough that a Pushed Power is needed, regardless of the bystanders?
- Would such frequency of using powers (i.e: one per round for 3-4-5 rounds) demand periodic auto-corruption tests (representing the Psyker is becoming power-maddened)? Or maybe it's nothing out of the ordinary for a hardened Astropath (we often have tons of years of practice before joining a Rogue Trader crew)?
I'm sincerely just trying to be useful to my RT, but I also don't want to be power-playing the character, so any opinions or suggestions on these would be greatly appreciated.
