Arena
One of the main draws of Rhombus Square is the Arena. Here, players can compete in scored matches against previously-fought enemies and win Arena Coins, which can be traded for powerful equipment and cosmetic items.
The arena has many Cups, which can be unlocked by default or by completing specific parts of the main game. Each cup consists of one or more Rounds. In a round, you must fight and defeat specific enemies, which often spawn in two waves. The rounds can be taken on individually, although it is necessary to complete each round in order to unlock the next one. The cups can also be taken on in Rush Mode, in which all rounds are played in series, with Lea recovering half her health between rounds.
Your performance in the arena is scored, and your score can award you with Medals and Trophies, as well as Arena Coins which can be used to buy equipment and cosmetic items.
List of Arena Cups
There are three types of arena cups. The standard cups are Solo Cups, which have you fighting alone against various CrossWorlds enemies. Team Cups are similar, but allow you to bring your teammates with you. Custom Cups are cups created by other characters in the story; due to this, they do not award Arena Coins, but may include enemies that aren't officially part of CrossWorlds. There is also a tab for Custom Team Cups, but there are currently no cups of this type.

Scoring
Your performance in the arena is given a score. The table below lists and explains the various factors that count towards your score.
Several score items benefit from a Chain Bonus. Killing enemies will increase your Chain Multiplier, which multiplies the points obtained for those items. However, taking too much damage or spending too long without damaging any enemies will reset your Chain Multiplier to zero.
| Score Item | Explanation |
|---|---|
| Damage Done | Total damage dealt to enemies, which is typically equal to the sum of their max health. Additional damage on an already dead enemy does not count. |
| Effective Damage | Extra points for all damage dealt that the enemy is weak against. This counts the amount above the default damage for any damage with a ^ symbol, which includes elemental weaknesses, break states, and Mark. |
| Damage Taken | Removes points equal to 25 times your damage taken; in PVP rounds, this is instead just your damage taken. |
| Elimination | 500 points per regular enemy kill. |
| Elimination Chain Bonus | 500 additional points for each level of chain you have before the elimination. |
| Boss Elimination | 5000 points per boss kill. |
| Boss Elimination Chain Bonus | 5000 additional points for each level of chain you have before the elimination. |
| Multi Elimination | When several enemies are killed as a group, 1000 points per enemy after the first one. |
| Multi Elimination Chain Bonus | 1000 additional points for each level of chain you have before that specific enemy was eliminated; the chain multiplier continues to increase with each enemy in the multi elimination. As the first enemy starts a chain, all multi eliminations will receive this bonus. |
| Environment Kill | 1000 points each for killing enemies with the environment. These points are rarely possible to obtain, as most arena rounds do not have sources of environment damage. |
| Overkill | 10 points each for killing an enemy in one hit. |
| Overkill Chain Bonus | 10 additional points for each level of chain you have before the elimination. Unlike other chain bonuses, this one applies the multiplier before the kill increases the chain. |
| Level 2 Art Finisher | 500 points each for killing enemies with level 2 combat arts. Not all arts properly add this bonus. |
| Level 3 Art Finisher | 1000 points each for killing enemies with level 3 combat arts. Not all arts properly add this bonus. |
| Element Overload | -10,000 points for each elemental overload. |
| Enemy HP Recovered | Negative the amount of HP that enemies have healed. |
| Perfect Guard | 100 points (initially) for each perfect guard performed, however perfect guarding x times in a row will reduce the score by a 1/x multiplier. |
| Perfect Dodge | 100 points (initially) for each perfect dash performed, however perfect dashing x times in a row will reduce the score by a 1/x multiplier. |
| Enemy Break | 500 points for each time an enemy is broken. |
| Guard Counter | 500 points for each guard counter performed. |
| Status Inflicted | 250 points for each status effect inflicted. |
| Rounds Won | In PVP, 5000 points for each round won. Due to the nature of PVP matches, you will always get 25000 points from this. |
| Rounds Lost | In PVP, -5000 points for each round lost. |
Bonus Objectives
In addition to these fixed point sources, individual arena rounds will have one or more bonus objectives that award a variable amount of points for achieving a goal. Possible bonus objectives are listed below.
| Bonus Objective | Notes |
|---|---|
| No Damage Taken | Worth 10000 points. It is not listed in the round overview, but is still present in every arena round. |
| No Items Used | Worth 5000 points. It is not listed in the round overview, but is still present in every arena round. |
| Time Bonus: # Minutes | Going over the specified limit will earn you partial points, reducing to zero at twice the limit. This bonus objective is available in every arena round. |
| Deal # Effective Damage | |
| Take less than # Hits | |
| Use at least # Combat Arts | This rare bonus objective appears only in the two rounds against Dirty Frobbits. |
| Reach a #x Chain Multiplier | |
| Use less than # Items |
Scoring Strategies
While the strategy for individual rounds can vary, some general advice based on this scoring system can be given. Effective damage is a very generous source of points, which makes it undesirable to be too overpowered, since dealing more damage while breaking an enemy means they have less HP to deal effective damage to once they're broken. Taking damage is heavily penalized, which makes tanky builds less effective; it is typically better to use an offensive build and focus on dodging attacks. And for rounds with large numbers of enemies, getting a high chain multiplier can provide a substantial boost to your score, so be careful to avoid attacks and don't stop attacking for too long.
Awards
Your score for each round determines the medal you receive for that round. The medals are Bronze, Silver, Gold and Platinum. Bronze simply requires you to beat the round, while the other three medals have required score thresholds.
Rush Mode also has a medal. This medal is based on the total score from all rounds in the rush, compared to the sum of all round thresholds.
Once all rounds in a cup are completed, you are awarded a trophy, which are also available in Bronze, Silver, Gold and Platinum (as well as True Platinum). This trophy is based on the average of all medals in the cup, including the Rush Mode medal. If you have both a platinum trophy and a platinum Rush Mode medal, you will receive a True Platinum trophy. As single-round cups do not have a Rush Mode, a platinum medal results in an automatic True Platinum trophy.
Platinum medals and trophies have no in-game effect, and exist only as bragging-rights rewards. Lower levels will affect arena completion and arena coins.

Arena Coins
Earning medals in the arena awards you with arena coins. The number of coins available per round depends on the cup, but a bronze medal will award 20% of the total coins, a silver medal will award 50%, and a gold medal will award 100%.
The Rush Mode medal also awards arena coins, but is worth significantly more than other medals, and will award half as many coins as all of the round medals in that cup combined.
Custom cups do not award arena coins.
Arena coins can be used at the Arena Coin shop to purchase various items, including many powerful pieces of equipment and cosmetics. The A New Home DLC adds items to upgrade the arena equipment, and items that grant bonus CP. Only one of each item can be purchased from the shop, and there are enough arena coins obtainable to purchase all items.
