There is one main type of earnable currency in Arcaea, Fragments. The total Fragments held by a player are displayed in the upper-right of the game screen (except in gameplay or cutscenes). There are also several types of consumable items with various functions: Ether Drops, and Cores.

## Fragments

* Unlock songs with a Fragment requirement (after completing song requirements).
* Refill 6 stamina in World Mode (24 hour cool-down) - 1000 Fragments.
* Unlock certain World Mode maps.
* Boost progress in Legacy and Beyond World Mode maps.
* Extend your available friend slots.
* Unlock songs with a Fragment requirement (after completing song requirements).
* Level up Partners - 10 Fragments.

Fragments can be earned by playing songs in Music Play mode or World Mode, from rewards in World Mode maps, or from Course Mode rewards. Fragments earned from song plays depend on the song's level and difficulty (specifically its Chart Constant), score, clear status, and the partner's skill and FRAG stat. Fragments earned after a play are categorised as:

* **PLAY** - Fragments earned after losing a track.
* **CLEAR** - Fragments earned after clearing a track.
* **PERFORMANCE** - Fragments earned after clearing a track with a Full Recall or Pure Memory.
	+ The CLEAR amount is reduced in this case, but the overall amount is higher with the bonus.
* **FIRST CLEAR** - 10 Fragments rewarded for clearing a song the first time.
* **PARTNER** - Fragments rewarded as bonus or lost as penalty due to the selected Partner's skill. This bonus is applied **before** multipliers.

### Calculation

In these calculations:

* "Difficulty" refers to PST/PRS/FTR/BYD. PST, PRS, FTR, and BYD have a value of 1, 2, 3, and 4 respectively.
* "Level" refers to the numerical level of the chart. ? has a value of 1, 9+ has a value of 9 and 10+ has a value of 10.
* PLAY/CLEAR/PERFORMANCE fragments are calculated differently, depending on clear type:
	+ TRACK LOST:

* TRACK COMPLETE:

{\displaystyle \text{CLEAR}=\text{Difficulty}+7+\left\lfloor\dfrac{\text{Level}}{1.2}+0.2\right\rfloor}

* FULL RECALL:

{\displaystyle \begin{align}

\end{align}}

\text{CLEAR}&=\text{Difficulty}+7\\
\text{PERFORMANCE}&=\left\lfloor\left\lfloor\dfrac{\text{Level}}{1.2}+0.2\right\rfloor\times2.7\right\rfloor
\end{align}}

* The total fragments earned are then summed, and a multiplier applied based on the Partner's FRAG stat. The multiplier is given by FRAG/50, i.e. every 1 FRAG above or below 50 equates to 2% fragments above or below the default amount
	+ For example, a FRAG stat of 70 gives a x1.4 multiplier, i.e. a bonus of 40% Fragments.
	+ Values are only rounded after all calculations, despite intermediate Fragment rewards being displayed with only one decimal place.

### Upgrading Partners

Fragments can be spent in batches of 10 to upgrade a Partner, similar to Ether Drops:

* The amount of Fragments used to upgrade a Partner, however, can be any integer value if the player possesses an amount of Fragments that is not divisible by 10.
	+ This can be done by maxing the amount the fragments used to upgrade a Partner, and then reducing by 10 at a time by pressing the minus arrow.

It will not be possible to upgrade Partners if the player holds fewer than 10 Fragments at a time.
The experience gained from spending Fragments can be calculated as

# EXP Gained
Amount of Fragments spent
×
2

{\displaystyle \text{EXP Gained } = \text{Amount of Fragments spent}\times 2}

The amount of EXP required to level-up a Partner can be seen here.

 Arcaea Website

**Switch:**
*Memories are not included in Arcaea for Switch. DLC must be purchased directly from the Nintendo eShop.*
## Ether Drops

*Main Article: Partners § Ether Drops*

Ether Drops are consumable items that provide an alternative EXP source for levelling up Partners. Ether Drops are earned as rewards in World Mode, and as bonuses for purchasing **Mobile:** songs or **Switch:** DLC song packs.

## Cores

*Main Article: Partners § Cores*

Cores are consumable items required to Awaken Partners, which raises their level cap from 20 to 30 and grants them new skills. Cores are earned as rewards in World Mode.

## Warped Shards

**Mobile:**
Warped Shards are consumable items that can be used to play Courses in Course Mode.

Currently, Warped Shards can only be earned from rewards in World Mode. Warped Shards can be used to replace the 4 Stamina requirement of entering a course, as well as allowing players to play any course even when one or multiple songs within a course are not owned by the player.

Warped Shards that are spent to launch a course will remain permanently consumed. As there are only a limited amount of Warped Shards available for collection, it is advised that players consider carefully about using Warped Shards instead of using stamina to play a course if the player owns all the songs in the course.**Switch:**
*Warped Shards are not included in Arcaea for Switch. Courses in Course Mode can be played without limitations, as long as the relevant charts have all been unlocked first.*
## 5th Anniversary Ticket

Tickets that were obtained but unused were automatically converted to 55 Ether Drops on expiry. The ticket was available as a reward in the 5th Anniversary event map.**Switch:**
*This item is not available in Arcaea for Switch.*
