This is probably a general question, though in particular it's going to be for Pathfinder and the Pathfinder character sheet. Generally, the way I (as GM) have been doing things in Roll20 is to create a character which represents a generic type of NPC (goblin, town guard, hill giant), and then used a token for each individual instance of that creature type. So all instances share one character, and I've used the 3 colour stats on the token to represent unique things (hitpoints (green), AC (blue) and a bonus to hit/damage (red)). These colours aren't tied to the attributes on the character. Looking at character sheets though, a lot of the normal bonuses/penalties are built into the character, and to make use of this every token would need to be backed by it's own character. Is this how people generally do things? One character per token for every NPC? It seems a bit heavy weight, and would make it hard to tweak all creatures of a particular type, but I can't see an obvious way of taking advantage of character sheets if I continue doing things my old way.
