Has anyone built one? I'm thinking about making a campaign around a criminal-ish, "Ocean's 11" type of group; I have other prepared classes in mind, but the Mastermind is the primary one I really wish to include. Having no experience yet with the class, I wondered if anyone here has playtested it or theorycrafted a build to any degree. I'd appreciate any feedback so I can begin to build the campaign's world around such abilities it would bring to the table.
For reference, there is no wrong answer. I build my campaigns once I know the classes being played, and I do have a ban list of classes, so we don't need to worry about things such as "Wizard/Arcanist does it better".
