World Mode Mechanics

Not to be confused with Story.

World Mode is where content such as songs and Partners can be unlocked by progressing through maps. This mode was added in version 1.5. Partners can gain EXP and level up when playing in this mode. Only registered users who are logged in have access to this mode.

Chapters & Maps

When the 'World' button on the main menu is pressed, a chapter selection screen is displayed. Upon selecting a chapter, a map selection screen is displayed. Many maps have unlock conditions, such as spending Fragments or purchasing song packs.

Progression

Tiles & Steps

The hexagonal spaces forming a zigzag up the screen are called Tiles. As you climb up the Tiles, you can receive the rewards stated on them. In order to progress, you need to gain Steps by playing songs. The number displayed under each Tile is the number of Steps you need to get to the next Tile. For more detailed information (Step count and reward) on each individual map, see World Mode Data.

Tiles, as well as Steps, are counted starting from 0 instead of 1, and Steps only have 1 decimal place.

• To complete a map, you'll need to progress the number of Tiles displayed on the map selection screen + 1.
• To move to the next Tile, you'll need to gain the number of Steps on the current Tile + 0.1. Hence, you might have gained enough Steps, but have not moved to the next Tile. However, the final Tile on every map has a Step count of 0, so the additional 0.1 may be omitted.

Calculating Steps

The amount of steps gained per song depends on the Chart Potential and the selected Partner's STEP stat. It may be calculated as:

$\text{Steps Gained} = \bigl(2.45\sqrt{\text{Chart Potential}}+2.5\bigr)\times\dfrac{\text{STEP Stat}}{50}$

Every 1 point of STEP stat above 50 corresponds to +2% steps, and every 1 point below 50 corresponds to -2% steps. This is similar to the multiplier for Fragments based on FRAG stat.

Stamina

Unlike Music Play mode, you must consume two Stamina for each song play. Stamina can be recovered in three ways:

• 30 minutes for 1 stamina (6 hours for a full refill from an empty meter)
• 50 Memories for 6 stamina
• 1000 Fragments for 6 stamina

If you don't have enough Stamina, the "Music Play" button will be greyed out.

Disabled Play Button

If you recover stamina using Fragments, you will have to wait 24 hours until you can do so again.

Your Stamina can exceed the maximum amount of 12, shown on the bar as +N. Theoretically, there is no limit to excess stamina, but the highest that players have managed thus far is +7.

Rewards

After playing a song, your partner will receive experience points (EXP for short), and you'll gain Steps determined by chart potential (see Potential). You will not gain Fragments, but it will affect your Potential.

Legacy

Since v1.7.0, special chapters known as Legacy chapters have been introduced. In these chapters, the number of Stamina required per play (by selecting "Play") is reduced from 2 to 1.

Play+

A "Play+" button is available in these chapters, where one can multiply Step and partner EXP gain by spending more Stamina and/or Fragments.

Playing a song by selecting "Play+" requires 2, 4, or 6 Stamina, and results in ×2, ×4, and ×6 multipliers respectively. Fragments can also be consumed to further upscale the multiplier: consuming 100, 250, and 500 Fragments results in ×1.1, ×1.25, and ×1.5 multipliers, respectively.

Boost

Since v2.4.0, one can multiply Step and partner EXP gain in non-Legacy chapters as well by spending Memories.

By selecting the Boost icon, 50 Memories are consumed for the next play, which results in a ×4 multiplier for Steps and EXP gained.

Chapter 0: Extra

Chapter 0 contains one map (0-B) that can be replayed indefinitely. In addition, all limited-time events are listed here. These can only be completed once and disappear after the stipulated end time. There are also unrestricted events with unlockable songs and Partners.

Limited Event Map

This is a single map, 0-LE (Limited Event), used to host all limited-time events.

Although each event is available only for its listed duration, returning events are possible. For each returning event, past progress on the event is restored.

Tile Types

There are many different types of Tiles, each with its own function. The required Step count for one Tile generally differs from Tile to Tile.

Name	Tile Icon	Label Icon	Description
Tile		None	Uncleared and cleared Tiles have this appearance, with the addition of the required Step count on uncleared Tiles.
Current Tile		None	Your currently selected Partner is displayed above this Tile, and the remaining Steps to move to the next Tile is displayed on the bottom.
Song Restriction Tile			To progress on these Tiles, you need to play a specific Song or Song Pack. There is no restriction on difficulty.
Fixed Speed Tile			To progress on these Tiles, you need to play Songs under a predetermined Note Speed. There is no restriction on difficulty. So far, only "Speed = 2" restriction Tiles can be encountered, but future updates may implement more Speed restrictions.
Random Song Tile			To progress on these Tiles, you'll need to play a randomly-chosen Song either from the whole collection or limited to a certain Song Pack. There is no restriction on difficulty.
Stamina Plus Tile			Upon ending a turn on these Tiles, the listed amount of Stamina is recovered. In order to receive the listed Stamina amount, you must end a turn exactly on the Tile. No Stamina is replenished if the Tile is missed.

Map Icons

Icon	Name	Description
	Map Complete	The green "COMPLETE" banner appears once a map is completed. These maps can no longer be accessed. Certain game updates extend maps, which removes the banner from those maps.
	Current Map	The most recently accessed map. From 2.2.0, this map can be immediately accessed from the Main Menu by pressing the Continue text at the bottom of the World Mode button.
	Map Reward	The image in the icon indicates the next reward to be unlocked. A check mark indicates that the next reward is already owned. This is only for players who had played the songs or unlocked the partners before World Mode was implemented in 1.5.0.

World Mode Data

These pages are lists of step data and reward data fetched from the game server API. They are not likely to change, though it is possible for them to be reset in the game server.

Notes: Tiles on a map are divided into groups of 5 tiles. This might aid in calculations.

For ease of navigation, data sheets have been separated by chapter.

• World Mode Data Chapter 0: Extra
• World Mode Data Chapter 1: Lost World (Legacy)
• World Mode Data Chapter 2: Outer Reaches
• World Mode Data Chapter 3: Spire of Convergence
• World Mode Data Chapter 4: Dormant Echoes

Trivia

• When playing a song in World Mode, you cannot retry until you finish or quit a song and return to the map.
  • Quitting a song in World Mode will abandon it. You will not earn progress (Steps and EXP). Moreover, the consumed Stamina will not be refunded, even though the song is not completed.
• Extra II, despite being named chapter3_light internally, has both Light and Conflict songs.
• The buildings in the background of Chapter 3 strongly resemble and are likely inspired by real-world constructs:
  • Left building: National Library of St Mark's in Venice, Italy.
  • Middle building: Milan Cathedral in Lombardy, Italy.
  • Right building (behind middle building): St Mark's Campanile in Venice, Italy.
• The World Mode icon changes when a new chapter is released. Past icons were:

Chapter 1	Chapter 2	Chapter 3
