Drop from Unity NM Intuila in Bibiki Bay. Can be upgraded to +1 using 50 Intuila's Hides. NM also drops: Intuila's Hides, Assiduity Pants +1, Nourishing Earring and Nourishing Earring +1.
Finally... The iLvl replacement for Nares Trews. Very nice. Now we are 1/3 of the way from not having to ever do NNI again. Its been around for years, and I've still only ever gotten one win in it.
Now we just need them to make iLvl counterparts to Phorcys Korazin and Thaumas Coat and we can kiss that horrid event goodbye.
