One of my favorite tools to use when developing an adventure, magic item or even a story is using tarot cards. I've got about six or seven different decks. For my current task, I'm using the Dark Grimoire Tarot. It's a tarot deck inspired by HP Lovecraft stories. Need I say more?
I'm working on a the micro sandbox, Misanthropic Islands, and in area two the players encounter a area blasted by shards of stone. Mixed within the stones is a massive 100' diameter wheel with script in the center and symbols on the edge.
It's what I am currently calling Wheel of Fate, a tool of judgment used by the stone giants. The wheel is divided into a 12 equal parts. Some good, more bad. I'm using it like a Deck of Many Things.
How do the cards come into play? I grabbed the tarot deck, give them a good shuffle then start flipping over the cards and stop on ones that strike some spark for me. Some symbol and a consequence/reward that goes with it. I keep the game mechanics very simple. But using the wheel can be deadly. Here is some of what I've come up with.
Okay, back to work.
