Future raid events will feature a new factor known as raid boosts.
Raid boosts bolster your team for the corresponding raid event with effects such as increased damage dealt to enemies or boosted adventurer HP.
You can get these raid boost effects when you clear boss battles and raid battles during raid events.
Use boosts to power up your party and challenge boss battles!
We're also adding new features in the next raid event.
Some of these features include a new Omega difficulty, the addition of silver and bronze emblems to the clear reward and Grand Bounty for Nightmare difficulty, the addition of special items to play the Extra Raid Battle whenever you want, and a feature that will allow you to trade for any of the elementally-attuned 5 ★ core weapons by clearing the extra battle.
For more information, see the notification for the next raid event.
