This is my current Advanced Coliseum Orion Blades:
This is the best I can do as the DURA went down to 88% success rate, and I still manage to enchant without breaking (thank my lucky stars!), though I could Cube down the Strength part to get some DURA back, but not enough to get Min to Lv.10.
Until I have more Ely, get the Master Hand title or Craft Mask, and more Advanced Enchant Remedy I'll want be enchanting the normal Coliseum Orion Blades with 216 DURA (but I believe I can cube it to 220+ DURA given the enchant levels on the blades).
I need to get these Advanced ones to +14 or something to make them excellent?
EDIT: Sorry uploaded the WRONG picture.
