Introductions
Welcome to our team composition guide for Mortenax Blade in Honkai: Star Rail. In this guide, we'll explore the best teams to build for Mortenax Blade, including recommended team compositions, character synergies, and everything you need to know to let your Blade teams bleed the battlefield.
Best Synergies for Mortenax Blade
Ashveil is one of Mortenax Blade's strongest teammates due to his ability to rapidly attack and support his allies. Since Mortenax Blade gains Charge whenever allies attack enemies (while his Zone is active), Ashveil efficiently accelerates his Talent-procced Skills.
Tribbie is a strong support option for Mortenax Blade, providing Vulnerability and All-Type RES PEN while requiring relatively few Skill Points. Additionally, Tribbie's ability to provide consistent amplification synergizes with Blade's own supportive capabilities, allowing teams to use both supports simultaneously, increasing everyone's DMG.
Acheron synergizes perfectly with Mortenax Blade due to his constant debuff application. Since enemies are afflicted with debuffs whenever allies attack during his Zone, Mortenax Blade can rapidly accelerate Acheron's Ultimate generation.
Additionally, Mortenax Blade fulfills the Nihility requirement for Acheron's major Trace while also activating his own Major Trace: Heart, Refined ad Infinitum, granting all allies increased Ultimate DMG. Combined with his numerous other buffs, this dramatically amplifies Acheron's ULT damage.
Feixiao pairs exceptionally well with Mortenax Blade due to her high action frequency. Since Mortenax Blade gains Charge whenever allies attack, Feixiao rapidly accelerates his Talent-procced Skills. Mortenax Blade also significantly increases Feixiao's DPS through various debuffs.
