Okay, I can't figure this one out. I'm using the standard Roll20 5E D&D sheet and I'm trying to make a macro that basically takes whatever my dexterity_mod is and add three to it in an emote (basically a simple spell notification for the GM and players). It doesn't have to change my AC or anything... /me casts Mage Armor and gives @{selected|token_name} a temporary AC of @[[dexterity_mod + 3]]
