There are already a dozen digital tools made by fans and posted across the net, including on the Daggerheart reddit. I've seen Spencer Starke posting there, so I know Critical Role and Darrington Press are aware of it. I guess we'll see how much they want to go after their own fans.
There’s probably a question here of profit, if you’re selling the tool vs providing it free. Also most of the tools I see are linking over to Demiplane for character sheet info, does that require a purchase to have or is the charbuilder there free?
