rare crafts no longer get 2 magick affixes since v1.3 unfortunately Grim Dawn Version v1.3.0.0 + Hotfixes (and the other rare crafts/+1 class faction belts can only roll 1 affix)
Ashes of Malmouth and Forgotten Gods Magic quality crafting recipes have been reclassified as Rare. These recipes now always generate at least one Rare affix, but their crafting costs have been increased
And a lot of MIs also can’t drop with double magick affixes at all (ex nemesis items)
Bunch of regular MIs can roll double magick, but seems like it’s being discouraged more and more
(someone even just requested to make all MIs roll at minimum 1 rare affix now 
)
