I was looking in the book but could only find a section that stated Navigator powers are standard actions but doesn't list if it's half/full and what subtype it is (attack/concentration/reaction/etc..)

Anyone know where this info is?

Check out the errata. That should fix up the action type issue.

For the other bits though? Good luck!

Once you have the errata though I'd suggest ignoring the bit in the FAQ in the end dealing with mutations. There are no rules for it and I have yet to see a good reason for it, so why bother? It just creates a headache and need for future houserules.

Ok yes I see the update with the type of actions it is but no info on subtypes

Guess i'll just use best judgement based on what the power does and compare it to psyker powers that do actions that kind of seem the same.

or you can send in a rules question and post here what you get back;-)
