Raid System

Raid battles are unlocked when you reach Rank 13. If you clear a raid, you’ll receive that correspond to the type of the raid. The goal here is to collect and exchange them. The most important things to exchange for here are the sacred artifacts that can only be obtained in raid exchange shop and materials to train them.

These are the artifacts that don’t rely on gacha to get, farming for them is one of the main contents of this game.

The number of attempts resets at:
 * 5:00 JST
 * 15:00 JST
 * 21:00 JST

Types of Raid Battles

 * Raid battles can be “summoned” (hosted) by using your AP, and you can call on other players to “rescue” the battles, which will cost them RP. When you host a raid, you will receive additional rewards. If you have AP to spare, you should host them due to the number of extra rewards you will receive from raid battles.
 * Rescuers (helpers) don’t receive these extra rewards.

Additional Rewards
(In the Q&A of the game, it’s stated that if the contribution is below a certain number, you won't be able to participate in the rankings and you won't be able to earn achievement points, but you will be able to obtain experience points and rewards.)
 * Host: Awarded to the person who hosted the battle.
 * MVP: Awarded to those with the highest contribution.
 * Vice MVP: Awarded to those who ranked below 1st but still high in contribution (2nd and 3rd for every raids at the moment).

Although damage has the greatest impact on contribution, other factors also affect it. Therefore, consider the timing of applying status ailments and debuffs when you attack. Especially for status ailments, you can’t stack ailments that have already occurred, so it’s a good idea to plan the timing as much as possible.

Rescue

 * Rescue is the act of notifying other players of the battle you are participating in. If you don’t do this, you’ll have to solo if you’re the host.
 * Battles are displayed on the rescue list depending on the time remaining of the battle. Older battles will be pushed to the bottom of the list.
 * Everyone participating in the same battle can call for rescue.
 * Rescue is possible even when your unit is wiped out. (The resurrection confirmation window disappears by tapping outside the frame).
 * There are three types of rescue: general rescue, friend rescue, and guild rescue. Calling for rescue has a cooldown of 5 minutes. All, friend, and guild rescue are independent, so you can send them separately.
 * The number of raid rescue requests in the title mission will increase by 1 when requesting rescue all at once, but it will increase by 3 times when requesting rescue individually.
 * You can also get a rescue code that can be copied and posted outside of the game. Use it when you can’t get enough helpers through general means, or when you want to notify your friends outside of the game.

Calling for general rescue at the start of a raid battle:

 * Pros: The HP of the enemy will be chunked down fast in the early stages of the battle.
 * Cons: If someone with less optimal strength joined in, there’s a chance that they will eventually fall off on damage.

Calling for friends or guild rescue at the start of the battle:

 * Pros: You can prevent people with less optimal strength from joining in, which will lower the chance of accidents.
 * Cons: Depending on the time of the day, there may not be enough people.

Estimate damage to join raid battles:
Even so, depending on the time of the day, there may not be enough people and you’ll have to call for rescue every five minutes.
 * Hard raid battle: If you can deal more than 100,000 damage, you can join from the start.
 * Extra raid battle: If you can deal more than 150,000 damage, you can join from the start.

If you call for friends and guild rescue to prevent accidents but can’t get enough people, you’ll have to send for all rescuers later.
