It's official, SE has some kinda weird Summoner Foot Fetish. Seriously hoping for Avatar: MAB in other inventory slots eventually... Nevertheless, these are the best boots without a doubt for magic bloodpacts... Until next pair...
Augments I received on these varied, The ones I Currently have on them IS MAB+12 PDT-2% Which i got with an NQ Stone.
Also Garota, good news is, Other pieces of this set have a lot of Pet oriented Augments.
These Skirmish sets see to have a large variet of possible Augments, Ranging from Magic Accuracy, to Pet: MAB...
The Hagondes Pants can get Avatar Perp-5 and even Avatar: MAB+. Real nice stuff they did with these sets and can really play out to some great SMN Gear.
I believe as long as you have more than around 80 total Avatar:MAB then you will get higher numbers from Convoker's Pigaches than these even at the full +50. So basically if you have even an Eminent Pole you should use Convoker's.
Dasva on BG mentioned to compare 2 sets you do (total pet mab)*(total pet dmg) and by using this method I got my above results.
