I know they removed the fettered option but...

By Gorrath, in Dark Heresy Rules Questions

...why does it say this in the rulebook if there's no more fettered power?

" By minimising the amount of power he draws, a psyker
can reduce the chances of horrible side-effects such as Psychic
Phenomena or Perils of the Warp (see page 195). When using a
psychic power, the psyker must choose an effective psy rating for
the power that is equal to or below his base psy rating. This value
must be at least 1."

That's a typo. They removed the rules for fettered powers but left some fluff text in the book.

Anyone has some house rules they're using in their campaign instead of the fettered option?

Something more risky than fettered but less risky than no fettered rule?
