This piece would actually be good for a Galkan SAM (like me :D) The Accuracy+10 is the same as Haubergeon and the Attack+20 is twice as good. Plus it doesn't give a -evasion, while it does give -50 HP, but what's 50 HP to a 73 Galkan anyway?
Now getting it versus Haubergeon or Haubergeon +1 is a very different story... ><
It's the Abjured version of the Cursed Togi. Have to find someone with ~100 skill in Woodworking to make it for you, then you have to take it to San d'Oria to uncurse it.
