Event Description

• Defense Frontline is an event where you challenge daily rotating Kaiju.
• Defense Frontline runs for 5 days.
• Different Kaiju appear from Day 1 through Day 5.
• You can attempt Defense Frontline up to 3 times per day.
• Your stage reached depends on the amount of damage you deal to the Kaiju. Reward amounts change based on your stage reached.
• A quest is cleared either after 8 rounds elapse or when the Kaiju is defeated.
• There is no defeat in Defense Frontline. You will receive rewards based on your stage reached.
• Rewards in Defense Frontline can be claimed up to 3 times per day. After clearing at least 1 quest in a day, you can skip your remaining attempts and earn rewards based on the highest stage reached that day.

Rewards

• Depending on the stage reached upon quest completion, you can earn rewards such as Dimensional Crystals, Crystal Shards, and ★5 unimaterials.
• The amount of certain rewards will vary even when clearing a quest at the same stage reached.
• For details on rewards, please refer to Defense Frontline > Rewards.
• The reward claim limit is refreshed at the daily reset.¹

¹ If you have remaining reward claims at 4:00 AM JST, they will be refreshed to reach a total of 3.

Mock Battle

• Mock Battles yield no rewards, but also do not consume challenge attempts.
• There is no daily limit on challenge attempts for Mock Battles.

Stage Effects

• In Defense Frontline, each Kaiju features unique stage effects.
• Utilize the stage effects to give yourself an advantage in neutralizing Kaiju.

Important

• A challenge attempt will be consumed even if you retreat from battle.
• If you retreat, the quest will be cleared based on the stage reached for the damage dealt up to that point.
• If you clear a battle when the daily reset occurs during the session, it will consume a challenge attempt from before the reset and grant rewards.
• Data for a suspended battle started before the event ends will be kept for 12 hours from the start of the battle, regardless of whether the event concludes during the suspension.
• After 12 hours from battle start, the battle will be discarded and no rewards will be earned, even if the event is still ongoing.
