The Evil Pieces, also known as the Devil's Pieces, are a set of 15 chess pieces given to top-class Devils to increase their ranks by reincarnating other beings into Devils.
Based on the game of chess, there are a total of 15 pieces (1 Queen ♛, 2 Rooks ♜, 2 Bishops ♝, 2 Knights ♞, and 8 Pawns ♟) that are given to top-class Devils (King ♚) with a peerage. These pieces are used to reincarnate other beings into Devils and become servants of the top-class Devil. The reincarnation abilities of the Evil Pieces, however, are not absolute as they cannot reincarnate Gods/Buddhas and Dragon God into Devils even with a Mutation Piece.
There are also special pieces known as the Mutation Pieces. If reviving a person requires more than one piece, then using one Mutation Piece would be sufficient in reincarnating that person instead of having to use several pieces. Mutation Pieces can be a Queen, Rook, Knight, Bishop, or Pawn. They are said to be very rare, and only 1 out of 10 Devils possess the Piece. Normal Evil Pieces can also change into Mutation Pieces.
Queens are worth 9 Pawns. Queens possess all the characteristics of Rooks, Knights, and Bishops, making them the most balanced piece as well as the most powerful.
Rooks are worth 5 Pawns. Rooks gain superhuman strength, leading to high offense and defense. However, they are not very quick, and can get beaten easily by a high-speed opponent. It was mentioned in Volume 2 and shown by Rias in Volume 4 that the King can perform castling with a Rook piece.
Bishops are worth 3 Pawns. Bishops gain enhanced magical abilities which they can use to conjure up a multitude of spells (offensive, healing, etc.). However, more powerful spells consume most of their magical power, which takes a long time to regain, forcing them to use their power carefully or risk becoming vulnerable to physical attacks.
Knights are worth 3 Pawns. Knights gain increased speed and mobility, enabling them to perform high-speed attacks and maneuvers. However, their main weakness is their low defense, making them vulnerable to powerful attacks if they are not careful. Another weakness among knights are their legs; if their legs are injured, their mobility is greatly reduced.
Pawns are worth 1 Pawn each. The traits of Pawns is the ability to promote into a Queen, Rook, Knight, or Bishop in enemy territory or with the permission of their King.
Sacred Gears also known as God's Artifacts, are items with powerful abilities bestowed upon humans by the original God from the Bible. They are one of the main points of interest in the High School DxD series
Only humans or human hybrids can be born with Sacred Gears. Angels and Devils can obtain them by resurrecting a human or human hybrid as one of their own. The Fallen Angels have devised a ceremony to extract and possess a Sacred Gear from the original user.
It is possible for an individual to own more than one Sacred Gear at a time. As to why Angels and Devils are never born with them, yet keep them when transformed from humans, is another mystery. Presumably because God never foresaw the new systems of reincarnating Devils and Angels which arose after His death.
Sacred Gears have an ultimate state of activation called the Balance Breaker, which is the most powerful manifestation of the Sacred Gear. Once reached, the Balance Breaker can be entered again far more easily than the first time. An incomplete Balance Breaker can be reached by self-sacrifice on the part of the user, such as when Issei sacrificed his left arm, allowing it to be transformed into a Dragon arm. However, this sacrifice method does not count as a true activation of Balance Breaker. Reaching the Balance Breaker can be triggered by the feelings of its possessor. Balance Breaker is said to be have been never intended, and that it was a flaw in the system created by God.
