A Trueform Pin is an accessory found in Super Mario RPG: Legend of the Seven Stars. When equipped, the pin prevents the party member from being turned into a Scarecrow or a Mushroom. The accessory also increases the party member’s Defense and Magic Defense by four points each.
A Trueform Pin can be earned by defeating Pandorite in the Kero Sewers. The accessory proves to be very useful during the level’s boss battle with Belome.
