Abyss Mode

Abyss Mode is one of the two new modes featured in the handheld versions of BlazBlue: Continuum Shift II, and in the console versions of BlazBlue: Continuum Shift Extend.

Special mechanics

 * 1) Shop: Here, the players use their accumulated money earned from playing other modes (or Abyss Mode) to buy status boosts or special abilities for their chosen character. Items are either unlocked by finding them in Abyss Mode or by increasing the player level. Each item can only be bought once per Abyss Mode playthrough, and are not permanent. When the player loses, the Shop will be reset and items may be bought again.
 * 2) Depth: While fighting enemies in this mode, a "depth counter" will steadily increase, depending on the number of successful hits, including Astral Heats. On most occasions, Depth will increase every two successful hits, except during Astral Heats that have extreme combo lengths, such as Makoto's or Litchi's. After a given depth, players will encounter "boss characters". Depth is not accumulated during a Boss Fight.
 * 3) "Boss characters": These characters have special status levels, and only appear at predetermined levels. They appear at Depth Levels 20, 40, 60, and 80 every 100 Depths, Depth 999, and the special Ragna the Bloodedge boss at Depth 666. Special statistics vary between the bosses. Early on, the bosses will be buffed-up versions (by way of status levels) of the standard characters, but later on, the player may also encounter strengthened Unlimited characters. After defeating a boss, the player can choose one reward out of five from a list. These are always randomly chosen, but can consist of status boosts, Reward boosts, Special abilities and positive (skip a certain number of floors) or negative (go back a certain number of floors) Depth boosts.
 * 4) Reward: After defeating enemies, the player receives a Reward. The total Reward can be seen in the upper left corner, above the player's HP gauge (where normally the points in Score Attack/Arcade would be shown) and in the upper right corner every 100 floors on the Abyss Menu screen, where the player can decide whether to go forward or leave the Abyss. The Reward added to the total after defeating an enemy depends on the Depth the player is at. However, keep in mind that if a battle is lost, players leave the Abyss empty-handed. The Reward accumulated until the loss will drop to the next 100th Depth. For example, losing on floor 236 will drop the Reward on floor 300, and to reclaim it, the boss there will have to be defeated. The reward will also stay on floor 300 if the battle against the boss is lost there, as players never got past that point. Another thing to remember is that if while trying to reclaim the last loss players were to lose on the way there, the old loss will be gone forever and the new loss will be assigned to its position (e.g. players have a loss to be reclaimed at floor 300, but lose on floor 150. The loss at floor 300 is erased and the new loss can be found at floor 200). The reward and EXP for playing Abyss Mode can still be received, as the two items are separate.

Status levels
Players can equally strengthen their own character to be able to match up with stronger bosses during the course of Abyss Mode. These boosts are listed in four categories.
 * StrLv: Short for Strength Level. Boosts in this category give more attack power to the character's attacks.
 * DefLv: Short for Defense Level. Boosts in this category give more health to the character.
 * HetLv: Short for Heat Level. Boosts in this category give more Heat to the character at the start of a fight. This also effects how much Heat is gained from attacks.
 * SpdLv: Short for Speed Level. Boosts in this category increase the overall movement speed (walking, dashing, Air Dashing), as well as the number of double jumps available to the character. A normal character with normal movement options in the air can have a maxiumum of four aerial jumps, and three air dashes with Speed Level maxed.

The maximum level of each category is 50. Above that, no more status boosts are accounted for. With level 50 on every status, the character has:


 * Twice as much HP.
 * Doubled damage.
 * A Heat stat of 100 at the start of a round, along with a much higher heat gain ability.
 * Doubled speed, along with four extra aerial jumps/three air dashes.

Initial Status levels can be bought in the Shop at the beginning. Those boosts range from +1 to +9. Should all of them be bought, Abyss Mode could potentially be started with Level 45 on all stats. After defeating a boss, there is a chance to get single Status boosts, or (albeit rare) a boost to all stats (called "All +1" or "All +2"). This makes for faster level gain on all stats.

Special abilities
Special abilities come in various forms. They can give another Break Burst Symbol, reduce the Heat consumption for Rapid Cancels to 25%, etc. Not all of them are unlocked by player level progress, some of them have to be won from specific bosses.

Only three Special abilities can be active at a time. In BlazBlue: Continuum Shift Extend, when a new Special Ability is selected, the player is given a choice as to which one they would like to replace. That said, it is better to choose abilities wisely, only switching out when truly necessary.

List of Special abilities
Here, all available Special abilities form Abyss Mode will be listed, along with unlock conditions, their in-game description and their price in the shop.
