Notes[edit | edit source]

  • Unlike other multiple shot items like Mutant Spider Mutant SpiderMutant Spider Icon.pngGrants quadruple shot but decreases tears. or The Inner Eye The Inner EyeThe Inner Eye Icon.pngGrants triple shot but decreases tears., 20/20 does not reduce rate of fire, effectively doubling damage per second potential.
