I'm currently in the middle of creating my first psyker character (after a long history of assassins and a few guardsmen) - however, I'd still like to remain traditional to my style of play with sneaking around at times. The only issue is, I can't seem to find any silent move or concealment skills/talents for a psyker. There are some psychic powers that help with it like chameleon, but I can't seem to see them gaining the benefit of those powers without the skills to back them up. Am I missing something, or would I need to elite advance these?

Savant Adjunct (rank 7) gets concealment. The Sabotuer altrernative rank from the free FFG PDF Salvation Demands Sacrifice has it too, and might be the perfect alternative rank for your character.

Not aware of any way to get silent move though. Try playing without those skills perhaps. We all have those skills we always take (mine is awareness) so will it really hurt not to? Try exploring uses of the psykers abilities; who needs to be sneaky when you can make people forget you were there?

Silent move and Concealment are both basic skills meaning you can use them untrained, at half the characteristic. Any bonuses you get to them (powers, the situation, etc) apply after the halving.

In our groop, we generally rule that any Basic skill is almost always available as an Elite advance, the logic being that if everyone is at least partially familiar with Silent Moves (say) then it should be easy to practice that/find training.

But short of trying to build with powers (shape flesh?) that can compensate somehow, it may be easier to spenf a few hundred XP on buying those Elite advances.

Since both concealment and move silent are basic its up to your GM to allow if you can take them as elite advances, but remember that as a psyker you get access to minor powers like chameleon which gives you a +30 to concealment, more if you overbleed it i think, I don't have the book on me at the moment so I'm not 100% sure one that. But point being, if you have a standard agility of 30, half for basic is 15 +30 for chameleon is a 45, that isn't bad considering that the guards may or may not have awareness and will have to roll against you. plus you can always use fate points to bolster or reroll should you be likely to fail.

Concealment is I think, more important since just becuase someone hears you move its a lot less likely that they are going to think "oh my emperor! there is an invisible person sneaking past me!" but more likely "what the chaos was that! I cant see a damned thing over there."

Psykers can do pretty much anything, also think about spasming a guard and slipping by while he cant react or get a chance to see you as you pass a concealment check.

Hope that helps.

The Telepathy discipline power actually negates the need. It completely removes any perception of you whatsoever, and the minor power Without a Trace from the Radical's Handbook means you leave no trace at all (no pict recordings, fingerprints, no sign you were ever there). Combine this with something like Forget Me for when either fail, and you have an untraceable, undetectable Assassin.
