For now, it's worded as "When this guest is friended," which is awkward and very distinctly modern. Ideally, I could just consolidate that whole line into a simple symbol, so I can refer players back to the rulebook where I have more room to state things in more detail. (It also makes the game easier to translate for foreign markets.)
Oh hey! I already have that symbol on the cards. It's the little icon of two stacked cards that appears with the Friend Bonus.
The special powers are a little complex to explain visually, especially in a small space. Here's the full list of powers with a quick first attempt at expressing them visually.
Lots to think about in the coming weeks. I look forward to testing these at small sizes and in actual play.
