Push Pin

Push Pin is a trinket.

Effects

 * Adds a 10% chance to shoot a piercing and spectral tear.
 * The activation chance depends on the Luck stat. The activation rate is equal to 1/(10 - (Luck / 2)). At base luck (0), the chance is 10%, maxing out at 100% at 18 luck.
 * Due to how this formula works, increases in activation rate are only seen with every 2 points of luck, as this formula rounds down after dividing Isaac's luck by 2.
