Got a head/legs so far, a 6-man party that only lost chain due to lack of mobs farming for 4-5 hours in cirdas caverns only came up with the legs from pyres. And I scrounged all the npc's even remotely near the ones mentioned in the OF thread, nowhere to buy them.
Then next day was randomly fighting mobs and had a pyre with a cirdas head III, got it to 5% but it disappeared after spamming 9 soul spectacles on it while I couldn't for the life of me get it below 5%. ...and the heads affect the quality of drops
