AoF vs AoL (in General)

So, what is better for a single mage with fireball with a DD familiar? I'm assuming AoF has the edge judging by the cost to acquire one, but is the amplification of the opponent's AMF (if they have one) worth it? I'm trying to read the descriptions in the help section and am kind of confused because I don't know how much of a benefit the AoF is to a familiar with a DD spell.

And for the AoLeadership, does it work on one minion? And if so does the effect transfer with junction? And+ if it does transfer, what has the bigger benefit for your tatoo... AoF or AoL? (assuming vs. AMF)

Just trying to weigh the pros / cons of each. Thanks.

If you're using a familiar, I'm 99.99999% sure the AoF with drastically outperform the AoL, if the latter works at all.

Use AoF and NSC's together

I would say always junction an AoF on to a familiar. Of course, if you have a minion or two in front of him that don't have an amulet, the AoL certainly couldn't hurt (you).

AoF.

The AMF amplification is cancelled out by the DD increase. The AMF effect stays exactly the same, unless AGs are involved. (These are on the familiar, of course. Your mage will suffer a decently large AMF jump.)
