Hello,
All things related to army building are easiest to find on the army builder. Either the official devil team one:
http://infinitythegame.com/army/ or there's aleph toolbox which is another option that can go on phones and such.
General rules for sectorials are in the human sphere expansion available in the downloads section:
http://www.infinitythegame.com/infinity/en/downloads/. In the army builder you can selecet a sectorial when choosing to make a new list. This has all the changes in it. Between the standard army and the sectorials normally only availability changes. In some cases the
SWC cost changes (unsure about points, never noticed) but the basic statline stays the same. And some units get the linkable rule.
Lastly I dont play pano so cant say.
