Body like spring wood, heart like dead ash. Yet embers of a craftsman's spark still linger at his fingertips. As ancient grudges are ignited once more, he promises to send both himself and the gods to the other side... Torn flesh, tempered a thousand times into a blade... What answer will it create?

Mortenax Blade Hypercarry (Acheron)

Mortenax Blade Hypercarry (Archer)

Since Mortenax Blade is a general debuffer, you can pair him up with most hypercarry Main DPS to give them a lot of vulnerability and damage increase to work with. You can run him with another hypercarry support, then a sustain character to complete the team.

Mortenax Blade Hypercarry (Ashveil)

Since Mortenax Blade is a general debuffer, you can pair him up with most hypercarry Main DPS to give them a lot of vulnerability and damage increase to work with. You can run him with another hypercarry support, then a sustain character to complete the team.

Mortenax Blade Hypercarry (The Herta)

Since Mortenax Blade is a general debuffer, you can pair him up with most hypercarry Main DPS to give them a lot of vulnerability and damage increase to work with. You can run him with another hypercarry support, then a sustain character to complete the team.

Mortenax Blade Beginner Team

For beginners who don't have any limited 4-Star or 5-Star characters yet, Mortenax Blade can be used as your debuffer or DPS in the team. March 7th (The Hunt) increases Mortenax Blade's SPD while dealing good damage of her own. Asta increases the party's SPD and ATK. Lynx will be the team's sustain unit.

Mortenax Blade Nihility Team

Mortenax Blade can also be used in a mostly Nihility team, with Acheron as the main DPS. You can run the team either sustainless or with a sustain character, as both compositions are viable. Sustainless teams are better with Welt since he can delay enemies.

Mortenax Blade Follow-Up ATK Team

Mortenax Blade can also be used in a Follow-UP ATK team, with Ashveil as the main DPS. Since his additional Skill from his Talent counts as a Follow-Up ATK, he will benefit from all the buffs a Follow-Up ATK team can provide.
