Hi there. For 4e D&D, it seems like the Defenses category is pulling just one mod out of the ability scores per defense score. Right now it looks like: Fortitude adds Constitution modifier Reflex adds Dexterity modifier Will adds Charisma modifier Each of these should be taking the highest of two modifiers as below: Fortitude adds highest of Strength or Constitution mod Reflex adds highest of Dexterity or Intelligence mod Will adds highest of Wisdom or Charisma mod Thanks for your attention in the matter, hope it'll get patched up soon! -Martturi
