The Seven Deadly Sins – Death Match (Raid Boss) Guide


Death Match is an event where 2 Players will co-op in real-time to overcome raid bosses in order to receive materials needed to Limit Break your character’s max level. Here are some things you should note before participating in Death Match (DM).

There are 2 ways to participate in DM. You can either Host a DM (up to 6 times) or wait for someone to invite you to a DM (unlimited). For the latter to happen, you need to be idle in the World Map or in Town.

To host a DM, you will need to fight in any Boss Battle. Each time you complete a Boss Battle, the “Death Match Rate” will increase. When it becomes 100%, the DM Boss will be summoned. You can increase the “Death Match Rate” gain by purchasing the following Decorations:

Boss Strategy

The first and the simplest boss that require some communication to make the fight very easy. Red Demon is not immune to Freeze or Petrify. The whole idea of this fight is to not allow Red Demon to make a single move. In order to do so, your team needs to have at minimum of 2 CC characters in total, 3 to be safe and 4 to guarantee a win. Communicate with your party member and let them know if you have a CC skill to end the turn. Make sure to cast your CC skill at the “Last Move (6th slot)” so that the CC will not be removed.

Recommended Characters

Individually, you can go 2 CC members and 1 Damage Dealer. Bring along a powerful Support to make sure your CP is high enough so that you can start the battle first.

This is a DPS-check battle which require you to have strong HP units and Attack Buffs. Since Gray Demon is a flying unit, you will not be able to attack it with melee base damage until its shield depletes and fall onto the ground. It will also land after 3 turns. Since the boss is immune to any debuff, it is important for your party to have at least one Attack Buffer.

Recommended characters

In a party setting, it is good to have at least 1 Buffer and 1 Healer in the team. Players will need to adjust your setup accordingly.
