Thought I'd share this with anyone who cares to read it. I work at a photography studio and we have a department that makes baseball cards. I had them use their baseball card stock to make the Danse Macabre and Crown of Command ending cards. Unfortunately this stock is slightly thicker and heavier than the card stock the other endings come on, and slightly more glossy. (So it's a dead giveaway when choosing a random ending to encounter). Instead, I created a simple chart to roll a d12 on for our endings:
1) Crown of Command
2) Danse Macabre
3) Crown and Sceptre
4) Ice Queen
5) Warlock Quests
6) Hand of Doom
7) Eagle King
8) Battle Royale
9) Judgement Day
10) Sacred Pools
11) Demon Lord
12) Hidden Variant ending (remove Sacred Pools and Warlock Quests, shuffle, and either draw at random or roll 1d10 and count from the top of the stack to whatever number the die rolls on, rerolling on a 10 result)
In related news, if I ever wanted to make another set of the Danse Macabre and Crown of Command cards, what would be a better solution? Would a place like Kinkos have the right card stock?
