Psyker-Players of mine tend to think about the Majority of Minor Powers as "useless". While do not agree "per se" with them, I would like to come along with some additional powers (especially since I want to keep all "full blown psykers" to have all the same Minor powers).
So far, I only came up with this one. Anyway, I am not sure about the balancing. Constructive input welcome!
The psyker lashes out with the force of his mind against the one of a nearby target. The target must be in seen by the psyker. If the psyker succeeds in calling onto his powers, the target muss pass an routine(+20) check for willpower. If the check fails, the target becomes stunned for one round.
Overbleed: For every 10 points of overbleed, the psyker can either increase the range of his power by 10m or heigthend the difficulty of the willpowercheck of the target by one step (from routine to ordinary; from ordinary to challenging and so on).
