Mortenax Blade is one of the strongest generelist supports and sub DPS in Honkai Star Rail. He can deal insane numbers of damage to all enemies, while also buffing his allies on the field. But to reach those high numbers, you have to use the correct build and play him in his best teams. So, here is a full HSR Mortenax Blade build guide to help find his best teams, light cones, and relics.
Honkai Star Rail Mortenax Blade Build
As Mortenax Blade is in the HSR banners, you need to know how to build him properly. Here is Mortenax Blade’s best build in Honkai Star Rail, with his best light cone, relic, stats, and planar ornament:
| Type | Information |
|---|---|
| Light Cone | Reforged in Hellfire |
| Relic | Divine-Querying Master Smith |
| Planar Ornament | Punklorde Stage Zero |
| Main Stats | Body: Crit Rate % Boots: Speed Sphere: HP% Rope: HP% |
| Sub Stats | HP% > Crit Rate = Crit DMG > Speed |
Prioritize getting 7000 or more HP on Mortenax Blade, as he completely scales on HP. Furthermore, invest in Crit Rate and try to hit at least 80%. He will have 100% Crit Rate with his Ultimate if you can hit it. Other than that, add Crit DMG and Speed. The following sections will give more insight into Mortenax Blade’s light cone, relic, and planar ornament options. Check the HSR tier list to learn about Mortenax Blade’s position in the current meta compared to other characters.
HSR Mortenax Blade Light Cone
- Reforged in Hellfire
- Lies Dance on the Breeze
- Before the Tutorial Mission Starts
- Resolution Shines as Pearls of Sweat
- Holiday Thermae Escapade
Reforged in Hellfire is Mortenax Blade’s signature light cone, and it is also his best in-slot option. This light cone greatly increases his Max HP, regenerates his Energy, and buffs the Crit DMG greatly. For a 5-star alternative, you can go for Cipher’s signature light cone, Lies Dance on the Breeze, which increases the Speed of the wearer and greatly decreases enemy defenses.
For 4-star alternatives, you can use Before the Tutorial Mission Starts as the priority, followed by Resolution Shines as Pearls of Sweat and Holiday Thermae Escapade.
HSR Mortenax Blade Relics
- Divine-Querying Master Smith
- Longevous Disciple
The new Divine-Querying Master Smith relic set is the best option for Mortenax Blade, and by a huge margin. It greatly increases the HP and Crit Damage, alongside the damage dealt.
Longevious Disciple is an old inferior version for HP scaling characters, so you can use it as an alternative if you haven’t farmed the new set yet.
HSR Mortenax Blade Planar Ornaments
- Sprightly Vonwacq
- Bone Collection’s Serene Demesne
Sprightly Vonwacq is the best planar ornament for Mortenax Blade, increasing Energy Regeneration of the wearer. It also lets them take the first action after entering battle. For an alternative, you can go for Bone Collection’s Serene Demesne, which increases the Max HP. However, the other part of this planar ornament’s effect is useless on Mortenax Blade.
HSR Mortenax Blade Teams
Mortenax Blade is one of the best new generalist sub DPS and support in the game. This makes him available for many teams. When it comes to his best team, Mortenax Blade is best paired with Ashveil, Tribbie, and Dan Heng Permansor Terrae.
| DPS | Support / Sub DPS | Support | Sustain / Support |
|---|---|---|---|
| Ashveil | Mortenax Blade | Tribbie | Dan Heng Permansor Terrae |
| Acheron | Ashveil | Welt | Mortenax Blade |
| Feixiao | Ashveil | Mortenax Blade | Tribbie |
| Evanescia | Elation MC | Yao Guang | Mortenax Blade |
| The Herta | Anaxa | Tribbie | Mortenax Blade |
| Castorice | Tribbie | Mortenax Blade | Hyacine |
As he has plenty of self-sustaining ability, he doesn’t heavily need a sustain to survive. So, you can play him as a fourth support and sub-DPS alongside Acheron’s and Feixiao’s team. For Elation teams, Mortenax Blade can also join Evanescia teams as the fourth character. Due to his HP-consuming mechanic, you can also play Mortenax Blade in Castorice teams.

Overall, I recommend getting Mortenax Blade as he can slot in multiple teams without any issues. Acheron players are particularly recommended to get him if they want to bring back the Nihility Emanator in the current meta.
