when ever I try to upgrade the Ninja Relic head to l109 all that happens is the NPC takes my Rem Tails and then tells me how many she is holding, I have completed COP and beaten all Dynaminsis . I have tried the base head and the upgraded head to no avail. I have upgraded the Ninja pants and Both the blm and thf heads to l109 with no problems . I have talked to both NPC's wile the armor is equipped and I am sure i am trading the correct materials .
