"The player can sacrifice cards at the infernal pit for gold and wildcards. Whenever a card is sacrificed this way, it cannot be returned back. The player can also win a card at the infernal pit. If the player provides a number of sacrifices, their chance to obtain the premium card grows. However, the infernal pit does not offer hero cards. The infernal pit offers a new card every eight hours. Different rarities have different requirements to reach full chance. Basically, it is the gold value of the card x20. \n* If the infernal deal card is a Common: A sacrifice worthy of 1000 gold provides 100% chance of winning \n* If the infernal deal card is an Uncommon: A sacrifice worthy of 6000 gold provides 100% chance of winning \n* If the infernal deal card is a Rare or Epic: A sacrifice worthy of 20000 gold provides 100% chance of winning. Premium cards provide double value in terms of determining your chances of winning the Infernal Deal card. For instance, sacrificing 10 premium uncommons gives the same percentage of win chance as sacrificing 20 non-premium uncommons. However, they don't provide double gold."@en . .
