To be correct, this thread has been started with large size medium security bases - but it was 50 pages ago at the time of 2.1 - and in-game rules and our knowledge about slightly evolved since then =))))Hi,
I noticed this thread starts as medium base listings yet I have seen that small are also supposed to have MEF. The Pathfinder app suggests so too. I am not finding them at all at the moment. Nothing but stufg I dont need. Even though I selected MEF on Pathfinder. RNG not being kind to me, is medium better?
I think that the most complete statistical data on materials yield is still here ("More stats" page).
Some very general rules -
1) upper limit of "rarity" increase with security level
2) number of "seeds" increase with size
And as always all is in the hands of RNGesus.
