Where is the 'Hero's (Accessory) of Maiming'?

[Ruethryl]

However there are Darklight "of Slaying" as well as Darklight "of Maiming". The fact is Monks and Dragoons use different gearstats for best results. There is an "Allagan Ring of Maiming" and an "Allagan Ring of Slaying".

Maiming = DRG, Striking = MNK, Aiming = BRD.

Slaying = Hero's gear, there are no Slaying Allagan pieces..
