In BB2, Soulstones are character-specific currency.

In other words, it is a currency that is not held in the account, but held individually by each character.

Soulstones are consumed for rerolling equipments and skills and for crafting, and the amount of Soulstones earned during the adventure is also important in the deeper level of the game.

Soulstones can be obtained from defeated monsters, but powerful elite monsters drop more Soulstones.

A choice must be made: take a risk and collect more Soulstones, or focus on stability and take the route with fewer enemies.

In BB2, unions will be core contents at the play cycle.

Players will always belong to one of the Unions, and will be able to earn Union Credit by accomplishing missions presented by the Union, and earn various rewards by progressing through progressions called Union Orders.

The union affiliation can be changed at any time, but not all union missions can proceed at the same time, and the adventurer created will be a character belonging to the union to which you currently belong.

Each union has its own characteristics, with different missions and order rewards.

Unions also play a role in furthering flavor, role-playing, worldview and story understanding.

Unions will be numerous and more will be added in major updates.

BB2 will feature “Inventory items” designed based on BB1 camp item system.

• Each character can have up to 5.
• They cannot be used during combat and can only be used while moving from one room to another.
• Inventory items obtained in the dungeon can be taken back to your warehouse and brought back to the dungeon when you start your next adventure with your next character.
• The default limit is 1 carry-on, but up to 5 items can be brought in by using a bag.
• If you are defeated in a dungeon, you will lose any inventory items in your possession.
  (Some items can be repatriated to the ground during the adventure or automatically sent back to the ground upon death.)
• Many inventory items can be obtained from the Union, but there are also rare items that can only be obtained through dungeon drops.
  Of course, you may not always be able to bring them back safely…

In BB2, the lab parts will be revamped, and the system will be reborn as a new training system.

The parts are divided into 5 parts: head, left arm, right arm, left leg, and right leg, and only one part can be brought back after each adventure to strengthen each setup (Race × Job).

It is important to choose parts while considering what kind of build you will ultimately build with that setup.

The contract in BB2 will be a new system that is completely different from BB1.

While equipments and skills normally available in dungeons are selected through rerolls, each contract offers multiple crafting menus, allowing for more conscious build construction.

Which contracts are combined depends on the build and style of play you are aiming for.

Rarity is an important factor in BB2.

Equipment that was called “legendary items” in BB1 will be represented by multiple rarities in BB2.

In other words, they are divided into 3 tiers: ★5, which has a high appearance rate and is obtained moderately often; ★6, which is rarely obtained; and the highest realty ★7, which may or may not be encountered once in dozens of hours of play. (★1 to ★4 are no-name equipment.)

Similar rarity settings are available for skills, runes, and inventory items.

Rarity was carefully designed to realize one of the production policies described below, which is to be able to take advantage of both improvisation and planning.

The ★5 items are stable performers and can be crafted by contract, so they are reliably available and serve as the core of the build.

Items from ★6 and up are difficult to target because their availability is limited to random drops in dungeons, and many of them have sharp performance, but if well matched to your build, many of them can exceed the power of items up to ★5.

Players will be tested on their ability to either faithfully realize the build originally planned, or to take advantage of opportunities presented by chance to make adjustments and changes to the build.

In addition, to ensure that many discoveries and surprises can be enjoyed for a long time in play, the ★6~ items are not merely upper-compatible with lower rarities, but are more unique and offer effects that cannot be achieved with other items.

Because BB2 completely redoes the level and battle design from scratch, many elements of BB1 will appear as completely different elements, although many of the names are still used.

For example, “Eternal Dark” has been changed to “Move the unique effect of another piece of equipment into an empty slot on this equipment” and “Diamond Dust” has been redesigned as a skill that “once activated, it will spread Stun until deactivated.”(They are still under development and may be subject to change.)

Some of the unique abilities are milder than in BB1, while many of the skill runes, which will be introduced at a later date, are as powerful or more powerful than ever before.

These redesigns in BB2 are based on the following concepts:

• The charm of the Buriedbornes series itself, “elements that make adventurers dramatically stronger,” will not be lost.
• Then, aim for a balance where strength is not dependent on any one element, but is achieved through a complex combination/composition as a whole.
• Give each user room to come up with their own unique build
• Improvisation and planning, so that both can be utilized to broaden the game strategy.
