The tarot mechanic is so lovely, and has the benefit of being both simple and flexible. I really enjoy being inspired by whichever deck I'm using when writing my healer's adventures. It's also nice that you have the option of ditching your party and either re-rolling or retiring altogether. I did use a d6 to randomize several things (e.g. the kind of party I'd join) but didn't feel I needed to do that to enhance the game.
