This is the piece you get for defeating Master Hoff in the last polymock quest. However, without a gold piece, polymock is pretty tough for a lot of people. I picked up an Iboga myself and was able to finally clear the polymock quests and get all the Asuran summon skills.
Trading this piece for 20-30k in gold (no ecto) or for 60 destroyer cores straight up. Can PM me here or catch me ingame as Rood Inverse.
WTS: gold Mirage Iboga polymock piece; cash or cores
