Alphollon C Meriard will remove the curse from a piece of cursed armor if you bring him the appropriate abjuration item. Hecatomb armor pieces require a Neptunal Abjuration.
Breakdown
The high quality version of cursed armor pieces are the -1 pieces. Turning in a -1 cursed armor will get you the +1 version of the armor.
I totally want this set for SATA :P But it'll be ahwile before I can get it. Not only high prices on cursed gear, but pretty hard to get the Abjs for them. I dunno.
