I'm in a game using the D&D 5E by Roll20 sheet, and I'm playing as a war domain cleric.  I'd like to add my war cleric ability as an other resource, and have it update automatically when my wisdom mod changes.  I've tried entering @{wisdom_mod} into the max field but that just displays that text, not the mod itself. I've tried searching and reading the wiki but I can't see a way to call an attribute. Also, my fellow player would like to know how to add their charisma modifier automatically to their initiative (Swashbuckler rogue)
