I'm running a 4e D&D game and one of my players is a beast master ranger. Now, of course, I've made a sheet for his pet so that it can have all its own stats and everything nice and separate, and we've also put the powers that use the beast's stats in the beast's sheet. However some powers, like Predator's Strike reference both the pet's and ranger's ability scores, so I'm wondering if there's a way to write the power macros on the sheet to reference ability scores from a different sheet.
