Infinite Mechanical Castle

The **Infinite Mechanical Castle (カラクリ無限城)** is a High Difficulty Mission Type. It was built as a tough training facility meant to test the true abilities of your Flower Knights. Defeat the strong Pest-type Karakuri on each floor, aim for the highest floor, and earn the exclusive Mechanism Medals.

The Castle features some of the most difficult content the game has to offer - with higher Floors geared towards high-level players.

## Team Composition

Form a party of 5 Flower Knights and their Flower Memories for each floor. Every floor has a list of **Recommended Abilities** and **Enemy Types** listed above your team composition, so keep this information in mind when planning your team and aim for the best composition possible. You can have up to 12 different sets of 5 Flower Knights and their Flower Memories.

## Normal and Hard Difficulty

In the Infinite Mechanical Castle, the player can select between two difficulty levels - **Normal** (通常) and **Hard** (破級). The Normal levels are relatively easy whereas the Hard levels are geared towards advanced players.

* The player can freely switch between the two difficulties.
* Progressing in one mode will count as progress in the other.
* The clear rewards are the same and shared between the two difficulties, so you can only get a floor's clear reward one time.

## Mock Battles and Challenging

You can choose to attempt a **Mock Battle** (模擬戦) or **Challenge** (挑戦) for each floor.

During a Mock Battle, your combat progress **will not be counted**, and the HP of your Flower Knights will be reverted back to their pre-battle states when combat ends.

When Challenging a floor, the remaining HP of your Flower Knights is retained after the battle if you are victorious. Upon clearing a floor for the first time, you will also gain Clear Rewards (if any) as well as progress to the next floor.

## Turn Limit

Some floors have a turn limit for battles. If you fail to defeat all enemies within the turn limit, you automatically lose.

Constructing an effective team of Flower Knights is key to defeating all enemies within the turn limit.

## Flower Knights' HP

All Flower Knights start with full HP and any **remaining HP** post-battle will be carried over to the next floor (This does not apply to mock battles). If Flower Knights with the exact same name are used, HP will be shared across them equally. The HP of all Flower Knights will be reset to full on the first day of each month.

* Different variants of the same Flower Knight **do not count** as "having the same name".
	+ For example, if a **Bloomed** Dancing Lady Orchid (Bride of Phos) is reduced to 50% HP, an **Evolved** Dancing Lady Orchid (Bride of Phos) in the same party will also be reduced to 50% HP.
	+ However, if a Dancing Lady Orchid (Valentine) is owned, her HP will not be affected.
* If Flower Memories and/or Equipment are added to a Flower Knight to boost their max HP, said Flower Knight's current HP % will be recalculated accordingly to reflect the boosted HP.
* During combat, any surplus HP gained as a result of Skills and Abilities will not go over a Flower Knight's maximum HP (in other words, you can't go OVER LIMIT).

* **The HP of all Flower Knights is reset at 0400 JST on the 1st day of each month**
(as of the August 1, 2022 maintenance).

## Healing Nectars

As evident from their name, these orange Healing Nectars can be used to restore 100% of your Flower Knights' HP.

* 20 Healing Nectars were given to players upon initial release. More can be acquired from the Castle's clear rewards.

## Enemy HP

When a party of Flower Knights challenges a floor and the entire party gets incapacitated, enemies' remaining HP will **not** be retained the next time you decide to challenge them again. Their HP will be reverted to a pre-combat state.

You have to defeat them with 1 party, so do try various team compositions if you are stuck.

## Ranking

The ranking tab displays the ranking of all your Comrade in Arms and their respective clear progress/points on Hard mode. This list refreshes every 10 minutes.

* These ranking results do not grant any rewards.
* Ranking is determined by two factors:
	+ Number of floors cleared in the Hard difficulty.
	+ Total points scored on cleared floors in Hard difficulty.

### Point Scoring

You can earn up to 10000 Points per floor. Scoring conditions are as follows:

* Number of Flower Knights alive after the battle (1500 Points per Knight)
* Victory with all Knights alive (500 Points)
* Received damage calculation:
	+ The less damage received, the higher the points awarded (Capped at 2000 Points)
	+ Formula: Let "Flower Knight HP at beginning of battle" be X:
	+ ((X - (X - Flower Knight HP at end of battle)) / X) x 2000

In order to achieve a perfect score, you have to defeat all enemies without letting your Knights lose any HP.

## Clear Rewards

Clearing a floor offers various rewards such as Ampules, Life Crystals, Flower Stones, and **Mechanism Medals (絡繰りの勲章)**. This currency is exclusive to the Infinite Castle and are used to purchase Wares.

* Clear Rewards can only be obtained once per floor.
* Clear Rewards cannot be obtained from Mock Battles.
* Clear Rewards are shared between Normal and Hard mode.

 Every multiple of 5
