So, if you were the DM of a 5E campaign where one (or more) of the players wanted to play a multi-class character, how would you handle that situation? Alternatively, if your favorite non-D&D tabletop RPG uses a class-based system, but lacks multi-class rules, what house rules would you use to fix that? Finally, the most important question: what cool name do you use for multi-class classes, other than the [Noun]/[Noun]/[Noun] template?
*This is not, strictly speaking, entirely true. The correct spelling of the official name for the TAZcast Fighter/Rogue multi-class build is, of course, "Ruf Boi".
