I'm going to rule tenatively that Garrett's Marshall Ability doesn't allow him to stack his charisma bonus to his intelligence bonus on anything but skill checks, but I could reverse that if you showed me the precise wording of the relevant abilities so I could make a ruling on them.  (I don't have access to the miniatures handbook at the moment, so I'm a little strapped to make a ruling)<br/><br/>Sorry to shut you down like that, but you're already nearly a physical god.  ;)
