Dark Esoterica (闇奥義, Yamiougi) is an effect which debuted in BS42, and is exclusive to the 'DarkStones' spirits. The Keyword is divided in two sub-keywords, Heaven and Hell. Dark Esoterica - Heaven counts cards of the designated color on the player's Hand and Removed Zone, while Hell counts cards on the Field and Trash. It is also worth noting that the "Heaven" of Pyroxene Esoterica is written as "Paradisiac Heaven," while the Dark Esoterica is written as "Heaven's Prison." In a similar fashion, "Hell" is written as "Earth's Prison," thus also being connected to the Pyroxene Esoterica - Earth keyword.
While each Esoterica is different, their effects are deeply ingrained with their respective colors, and are generally control-oriented. While their conditions have varying degrees of ease to achieve and punish color mixing, with The DarkStoneMaiden Alice, Dark Esoterica can be activated freely.
