Howdy Zavier Y. Not as such, no. Roll20, to the best of my knowledge, has no user-accessible if/then functions whatsoever. The things you're talking about are called "token icons" by most, and 'status indicator overlays' by the Wiki: Without the API ( a mentor-level feature ), what you ask is simply not possible. Mostly. I have one idea for a possible work-around which I'll share later in this post. With the API, it may be possible to do what you ask. I'm not sure, as I'm not one of the API wizards around here. You might ask in the API forum ; it's possible The Aaron, Vince, Brian, or one of the other API Wizards could come up with something. Barring that, one possibility could be a macro which looks for an Attribute on the character sheet. For example, let's say you want a cold damage macro that only affects those who are vulnerable to cold damage... Set up a character sheet, with an Attribute called "Cold", and give it a value of 0 or 1. 0 means they are immune to cold damage, 1 means they are not. Then a macro could look like: The White Dragon breathes cold at you and does [[ ((@{target|cold}) * (3d6)) ]] points of cold damage. Square brackets to make it an inline roll (hiding the mechanics). @{target|cold} calls up the value stored as the attribute "Cold" in the journal entry linked to the token you choose when you use the macro. Then, multiplying the dieroll (3d6) by the attribute's value (0 or 1) you get a response of either 0 or the dieroll, depending. This would return an output like: The White Dragon breathes cold at you and does [14] points of cold damage. Granted, you'd have to manually choose each target, but it's something. -Phnord
