Sup /tg/,
I need some helps. I am a recently new Dark Heresy GM but a long time player of Deathwatch. One of my players has said he would be interested in running an adventure or two using either DH or RT rules so that our group of 5 can have 2 GMs for occasions where I am not able to run a game.
So for this players turn at GMing I would like to play a Psyker as I have never played one before, always playing the Assassin or Dev or Tac Marine; however I find my self lacking knowledge in the fluff department as how to role play a good Psyker (also I have no idea which schools of powers are useless as fuck and which ones are awesome). I was thinking playing a telepath who's main form of fighting is making people kill them selves and friends but considering during the opposed WP test oppoents get a +30 to such commands it may not be a good idea.
Can /tg/ provide some help/advice/pro psyker tips?
