Raid Boss Strategy & Best Characters

---|---|
Plates | Slash Plate x4 Physical Plate x4 Elemental Plate x1 |
Features | - Has an AoE attack - Grants a Shield + when the Shield is broken, DMG Taken is increased (2 turns) - Grants ATK buff and DEF PEN Rate buff |
Use Slash & ST Attack Characters
In the Kaiju No. 2 Raid Battle, characters with ST Attack and the Slash Element will receive a Support buff. This provides a very high damage bonus, so prioritize using these characters.
Focus on CRIT Rate
A Support buff is also applied when a Critical Hit occurs. Use Uniparts and weapons to increase your CRIT Rate.
Defenders Are Not Needed
In Raid Battles, the number of turns is fixed, so they are not long battles. As long as your characters are not getting defeated, it's recommended to challenge with a formation focused on damage instead of using a Defender.

What is a Raid Battle?
An All-Player Co-op Event
Event Period | Until Boss is defeated |
---|---|
Eligibility | Player Rank 4 or higher |
Raid Battles are a cooperative mode where all players work together to take on a Kaiju. Rather than traditional multiplayer cooperation, each player independently damages a Kaiju with extremely high HP in real time.
Limited Action Turns/Rounds
Raid Battle Kaiju have massive HP, making it impossible to defeat them in a single fight. With a limited number of rounds, your focus should be on maximizing the damage dealt within that timeframe.
You Can Receive Support Effects

In Raid Battles, you can select a Support effect after each battle. This effect applies to all players, and you can also benefit from the Support effects chosen by others during the fight.
Complete Missions to Collect Points

Raid Battles feature missions where you earn rewards by collecting points. Since there are also daily missions, make sure to participate every day.
3 Stamina-Free Attempts per Day
During an active Raid Battle, you receive 3 tickets daily. Each ticket allows one challenge, so be sure to use all three each day. After your tickets are used, you can continue participating by spending Stamina.
