The Sulphurous Grabber is a Hardmode yoyo that drops from Sulphurous Skaters. While it is thrown, the yoyo will occasionally release nine damaging bubbles that can be either green or purple. If the yoyo touches a green bubble, it will power up, gaining increased damage and releasing bubbles more often. Only the yoyo can inflict the Irradiated debuff.
Its best modifier is Godly.
