Make genetic instability scale according to the mutations

[Dr_Bee]

I still think that making certain powers synergize for a diminished stability penalty would be pretty neat. it would give good geneticist something to more to search for. also I think there really should be some sort of benefit for handing out powers. right now the easy way to distribute powers is expensive, the hard and cheap way requires getting people to trust you not to kill them. consider this is SS13 think about how often the hard and cheap way is used.
