Do I require a physical Tarot deck for this, or will a virtual deck do just fine?
The tricky part of the mechanics of ARMORED BONES (and my other tarot deck roleplaying game, LAST CHARGE OF THE SENTRY ARCANES) is that the gameplay requires you to shuffle a Tarot Deck apart into two separate decks: one for the Major Arcana Cards, the other for the Minor Arcana Cards.
One thing you can do is use this TINY TAROT app (https://raindrinker.itch.io/tiny-tarot), which only lets you draw Major Arcana cards, then use a physical or digital deck of classic playing cards to stand in for the Minor Arcana deck (Spades are Swords, Clubs are Wands, etc).
His Majesty The Worm, another tarot-focused dungeon crawling game, also has some interesting alternatives to physical Tarot decks suggested on its website.
Thanks for your interest in my game. Hope you have fun with it!
