Warp talents

By Alox, in Proofreading Changes

The Bastion of Iron Will and the Warp talents in Mental fortitude refers to the users psy rating, but psy rating is not a prerequisite. Is this an error?

And how are non-psykers supposed to get access to Strong Minded?

It appears they get Strong Minded by wasting 600xp on Bastion of Iron Will. Which, as you point out, doesn't have Psyker as a pre-req.
