Monster Advancement in FG?

[A'egis Ward]

Does FG support scaling monsters to new CRs? Or, is there a way to edit a monster or duplicate an entry and then modify and save it for use?

Drag the creature to the NPC campaign list, unlock it and edit it. This will be available in that campaign only. Info in the 5E user guide here: https://www.fantasygrounds.com/wiki/index.php/5E_NPC_Sheet#Use_Existing

If you then want to use this creature in another campaign you can export it as a module. Info here: https://www.fantasygrounds.com/wiki/index.php/Library#Module_Export

Wonderful! Thank you, Trenloe.
