Interesting fact:
Tried to add 2 different Merlinic Hoods to my Gearswap. Exported the items and it seems that indeed the "big numbers" on the augments are a double roll internally. This is what gearswap spat out for my +8INT +34MACC +35MAC Hood:
"Merlinic Hood", augments={'Mag. Acc.+24 "Mag.Atk.Bns."+24','INT+8','Mag. Acc.+10','"Mag.Atk.Bns."+11'
This was a Pellucid piece. The only 30+ MAB roll I had with a Fern looks like this:
"Merlinic Shalwar", augments={'Mag. Acc.+18 "Mag.Atk.Bns."+18','Magic burst mdg.+10%','"Mag.Atk.Bns."+14'
