I have just finished reading Ravenore. Which got me thinking about adverseries for my players.
Cognitae training could a skill giving a bonus to int test.
Enuncia is the use of sound to munipulate the energies of the warp producing effects like psychic powers,
Enuncia could be used by granting characters to purchase powers as if they were a psyker. The powers would be unchanged but when casting the character use Intelligence instead of Will power. This would also work with perils of the warp as mispromunciation would have the same effects.
Any thoughts or ideas welcome.
