Demon Slayer Event Dungeon Details

Demon Slayer Event Dungeon is a Dungeon Collaboration Event where you will be able to tackle new challenges such as the Akaza and Doma Showdown.
Akaza Showdown Tips

The Akaza Showdown is a Boss fight dungeon with 4 different stage each presenting a higher difficulty than the previous instance.
Prioritize Attack Stats

As Concussion is a unique Debuff without an Immunity, it is important to increase your team's Attack stat to prevent your team from being stunned. Additionally, due to its long duration it is not uncommon for heroes with low Attack to be chain stunned.
Aim for Quick Clear

As Akaza can increase his Attack stat over the duration of the fight, it is likely that Akaza will eventually have a higher Attack stat in a prolonged encounter.

Recommended Team

|---|---|---|---|---|
Xiao Support | Ryan Sub-DPS | Biscuit Buffer | Rachel Sub DPS | Shane DPS |
The recommended team that is fairly flexible Rachel provides Debuffs to increase Shanes damage while Xiao and Biscuit provide buffs for the party. While optional having Ryan in the team can allow for a faster clear as the Cooldown Reduction will allow Shane to use her Skills more often.
New Player Teams
| Front Row | Front Row | Front Row | Front Row | Back Row |
|---|---|---|---|---|
Heavenia Buffer | Biscuit Buffer | Rachel Sub DPS | Xiao Support | Shane DPS |
A fairly F2P friendly team which includes heroes that can be obtained in the early to mid-game. Heavenia (Awakening can be replaced with any hero that provides an Attack buff for the party.
Tips! | Due to the high difficulty of the Event Dungeon, it is best to clear a lower difficulty dungeon until you have access to additional Legendary Heroes with Transcendence. |
