I posted a suggestion because there is no reason that the functionality shouldn't exist natively in Roll20 that I can see: Function to append a monster sheet with a template However I wonder whether this can be achieved readily with an API that asks for a Template sheet and a Target sheet, then appends the features, actions etc from the template onto (preferably a copy of) the target sheet with the template name appended as a prefix to the sheet name? Original text below: It would be good to have a function to Append an Monster Sheet with a Template for all those homebrew cases where an area or event creates a variant of existing monsters: e.g. Shadowy; Gribbly. If we could set up a template or NPC sheet with just the features / resistances / traits / actions etc we wanted, and then select which character sheets these to it would save a massive amount of time when trying to add richness to our games. So I could turn a Hobgoblin into a "Shadowy Hobgoblin" or "Gribbly Hobgoblin" for example, with the respective extra features. Surely virtually all the tech is already available in game to achieve this right? Here's hoping this is an easy win for Roll20.
