World Mode Mechanics

World Mode is Arcaea's equivalent of a story mode, in which 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.

Stamina

Stamina count. Image credit: Japanese Arcaea Wiki

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 (3 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.

• Originally, the waiting time was 3 days, but was changed to 2 days in 1.5.2, and then to 1 day as it is now in 1.7.0.

Your Stamina can exceed the maximum amount of 6, 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. The number of Steps earned is also influenced by your partner's STEP stat.

Every 1 STEP above or below 50 equates to 2% steps above or below what you would normally get. For example, if your song result is 10.0 and your Partner has a STEP stat of 50, you'll gain exactly 10 steps. If your Partner has a STEP stat of 80, you would get a 60% increase, which would be 16.0 steps gained. Conversely, if your Partner has a STEP stat of 30, you'll get a 40% decrease, which would only net you 6.0 steps.

Legacy

Since version 1.7, 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 the number of Steps achieved by spending more Stamina and/or Fragments.

Playing a song by selecting "Play+" requires 2, 4, or 6 Stamina, and results in x2, x4, and x6 Step count respectively. Fragments can also be consumed to further upscale the Step count: consuming 100, 250, and 500 Fragments results in ×1.1, ×1.25, and ×1.5 Step count, respectively.

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.

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 (1-7 and 3-5), 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.
Fragment Reward Tile			Appears identical to a normal Tile. Upon reaching these Tiles, the listed amount of Fragments are gained. You do not have to end a turn exactly on the Tile to get the Fragments, as opposed to Stamina Plus Tiles; you gain the Fragments even when moving past the Tile.
Song Reward Tile			Appears identical to a normal Tile. Upon reaching these Tiles, you'll unlock the displayed Song. You do not have to end a turn exactly on the Tile in order to unlock the Song, as opposed to Stamina Plus Tiles; you unlock the song even when moving past the Tile.
Partner Reward Tile			Appears identical to a normal Tile. Upon reaching these Tiles, you'll unlock the displayed Partner. All current Partners are situated on the last Tile of their respective Maps, so these Tiles cannot be missed.

Icon Reference

Picture	Meaning
	Map Completed The green "COMPLETE" banner appears once you've completed a map. You'll no longer be able to access it.
	Current Map The map you most recently left off in.
	Map Rewards A check mark means that you already own the reward. This would be for players who had played the unlockable songs before World Mode was implemented; the chapter may not have been played at all, but the rewards are owned.

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

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.
