The game upposed to be https://en.wikipedia.org/wiki/Potion-making:_Practice (Potion-Making. University Course with red and blue decks but should 7-8 cards in hands) which popular in my family. In fact every character was supposed to have somebody’s representation and Nyx represents me (with gender swapping) so this version should be first. But when we came to idea of using filly Nyx it was suspended.
 
“Eye of The Beast” amulet reduces damage taken from Elite Monsters by 10%. That’s how it works in “Royal Quest” MMORPG. Must be good for protector of ponies. Or may be it’s just a trinket coming with one of Equestrian versions of D&D games.
