Dynamic DC

Currently, Franz gives a static 15 DC for all types of scenarios irrespective of what you do. I feel Franz should be able to see the context of the action - or use the DC provided in a description the player made - and adjust the DC accordingly so you can have easy tasks and difficult tasks.

It would become a whole lot more immersive if my characters didn’t just walk through a mass charming spell after rolling a lucky 16 against 15 instead of the DC being something more like 21.
