Ruinous Souls are post-Moon Lord crafting materials that drop from Polterghast. They are used to craft two armor sets, numerous weapons, the Phantom Heart, and Stratus Bricks. 85 are required to craft everything they are used in, including one group of Stratus Bricks, or 76 if crafting only one Bloodflare headpiece and excluding Stratus Bricks, meaning Polterghast must be defeated a minimum of 17 / 15 or 16 / 13 times respectively.
