I haven't SB in HM dungeons in a while. I decided to duty queue for Halatali or Brayflox, I was bonding Zircon accessories (i48-49) as a BLM. These dungeons are i55, Dungeon iLVLs, which should have provided an optimal SB rate, as the mLVL should 7-10 levels above the items.
My accessories only gained 4% for the entire run. Did they re-nerf SBing dungeons again?
