Getting Back Into Sam, Nm / Af Tips

looking for some advice on how to go about getting my af3 necklace and body. i've heard some nasty things about the nms who drop them, and was hoping for some tips from fellow sams on how they got theres. the NM section just turns into math nerds going off on tangents about how A is 0.0000x% better than B, not giving any tips at all >_>; anyone with helpful advice is welcome.

tomorrow if i'm not doing anything vastly important, i'll go bear-blast mictlantecuhtli rq since he's a big fat joke

that aside, chione in uleguerand (tier two avnm)'s the ideal way of getting unkai body seals (or any other body seal for that matter) by warping out right as it's about to die so your t2 abyssite doesn't change into a t3
