Honkai: Star Rail Version 4.6 Phase 2 officially began on October 21, 2026, bringing back the 5-star character Mortenax Blade! Pearl's banner remains available until the end of the version, with Qingque, Xueyi, and Misha featured as rate-up 4-star characters.

The highlight of this rerun is the all-male Follow-Up Attack (FUA) team featuring Mortenax Blade, Aventurine • Waveflair, and Ashveil. Their abilities work together to trigger frequent chained attacks, making this a fun and powerful team for FUA fans.

This lineup focuses on frequent FUAs, DEF reduction, increased damage taken, and chained attacks, delivering smooth rotations and consistent team damage.

This guide covers Mortenax Blade's pull priority, best Eidolons and Light Cones, all-male FUA team compositions, Relic builds, and combat rotations to help Trailblazers decide whether he's worth their Stellar Jade.

1. Mortenax Blade Build & Role: The Key to Follow-Up Teams

Mortenax Blade Honkai Star Rail Character Art

Mortenax Blade

5-Star | Fire | Nihility

Role: Sub-DPS / DEF Shred Support / Field Enabler

Mortenax Blade's kit revolves around his Ultimate and field mechanics. His Ultimate activates a special field and applies debuffs to enemies, providing DEF reduction and increased damage taken.

As teammates continue attacking, Mortenax Blade builds up his resources and automatically triggers Follow-Up Attacks (FUAs), dealing extra damage while maintaining debuff uptime.

Why Is He Great for an All-Male FUA Team?

  • Strong Synergy: His Follow-Up Attacks help Aventurine • Waveflair build momentum while supporting Ashveil's FUA triggers.
  • E0 Is Enough: His field, DEF shred, damage amplification, and Follow-Up Attack mechanics are available without Eidolons.
  • Flexible Team Options: He works in both Follow-Up Attack teams and Acheron debuff teams.
  • Watch Your Rotation: His field involves HP consumption, and his Ultimate costs 160 Energy. Frequent team attacks help maintain consistent uptime.

Quick Verdict: If you already own Aventurine • Waveflair and Ashveil, Mortenax Blade is a strong E0S0 pickup. Otherwise, consider the cost of completing the full team before pulling.

2. Is Mortenax Blade Worth Pulling in HSR 4.6?

2.1 Pull Priority: Who Should Get Him?

Player Situation Verdict Why?
Own Aventurine • Waveflair + Ashveil Recommended E0S0 Completes the three-character FUA core and improves team synergy.
Own only Aventurine • Waveflair or Ashveil Situational Still usable, but the full FUA engine remains incomplete.
Own neither core character Consider Skipping Building a team around three limited 5-stars is expensive.
Own Acheron and want more team options Good at E0S0 Adds debuff utility and can support both Acheron and FUA teams.

For most Trailblazers, E0 Mortenax Blade already provides his core utility. You don't need high Eidolon investment to make the team work.

Planning to complete your FUA team during Version 4.6 Phase 2? Check your current pity, guarantee, and Stellar Jade first. If you need additional Oneiric Shards, explore HSR Top Up options and set a budget before pulling. Securing the characters you need matters more than chasing extra Eidolons.

2.2 Best Eidolons & Signature Light Cone

Recommended Investment: E0S0 → E1 → Signature Light Cone → E2

Eidolon / Light Cone Value Best For
E0 Full core kit with field effects, DEF shred, and Follow-Up Attacks. Most players. E0S0 is a solid stopping point.
Mortenax Blade E1 Eidolon E1 Improves field uptime and long-fight consistency while providing additional buffs. Dedicated FUA team players.
Reforged in Hellfire Mortenax Blade Signature Light Cone Reforged in Hellfire Boosts HP, Energy-related utility, and CRIT DMG for better personal damage and smoother rotations. Players with extra pulls who want higher damage.
Mortenax Blade E2 Eidolon E2 Strengthens Ultimate and Follow-Up Attack synergy, increasing his personal damage ceiling. High-investment players.
E3–E6 Additional damage upgrades with a significantly higher investment cost. Dedicated fans and E6 collectors.

F2P Recommendation: Stop at E0S0. E1 mainly improves rotation consistency and field uptime, while his signature Light Cone focuses more on personal damage.

2.3 HSR 4.6 Pull Planning: Mortenax Blade or Pearl?

Alongside the Mortenax Blade rerun, Pearl (Ice / Elation) remains available throughout Version 4.6.

Your Goal Pull Priority
Own Aventurine • Waveflair + Ashveil Mortenax Blade E0S0
Main Elation teams, need better sustain Consider Pearl first
Main Acheron, need another debuffer Consider Mortenax Blade E0S0
Want a fully invested all-male FUA team Get E0 first, then consider E1
Low on Stellar Jade, saving for future banners Save your pulls

3. Best Mortenax Blade Teams: All-Male FUA & Acheron

3.1 All-Male Follow-Up Attack Team

Mortenax Blade

Core Team: Aventurine • Waveflair + Ashveil + Mortenax Blade

This team uses frequent attacks to trigger chained Follow-Up Attacks, while DEF shred and increased damage taken effects boost overall team damage.

How Each Character Contributes

  • Aventurine • Waveflair: Main DPS who builds Elation-related resources through frequent attacks to trigger additional damage.
  • Ashveil: Core Follow-Up Attack enabler who marks priority targets and chains attacks with teammates.
  • Mortenax Blade: Provides field effects, DEF shred, and damage amplification while contributing automatic Follow-Up Attacks.

Best Fourth-Slot Options

Dan Heng • Permansor Terrae / Luocha / Gallagher

Want to keep the all-male lineup? Pick a sustain unit based on your roster and the content you're tackling.

For tougher endgame content, consider Hyacine or Huohuo for more reliable healing and better survivability, even if that means giving up the all-male theme.

Team Tip: Make sure your sustain is reliable before pushing for maximum Follow-Up Attack damage.

3.2 Acheron Debuff Team: A Flexible Alternative

Mortenax Blade isn't limited to FUA teams. He can also support Acheron by applying debuffs, reducing enemy DEF, and increasing the damage enemies take.

Recommended Team: Acheron + Mortenax Blade + Another Nihility Support + Sustain

His debuff application helps Acheron generate Slashed Dream stacks and access her Ultimate more consistently.

If you've already invested in Acheron, Mortenax Blade offers value beyond Follow-Up Attack teams, making him a more flexible roster addition.

4. All-Male FUA Team: Pros, Cons & Endgame Performance

4.1 Why This Team Is Fun to Play

  • All-Male Lineup: A unique team for players who want to bring their favorite male characters together.
  • Nonstop Follow-Up Attacks: Frequent chained attacks make the combat rotation fast and satisfying.
  • Multiple Damage Dealers: Damage is spread across the three-character core instead of relying on a single hypercarry.
  • Good Multi-Target Potential: Chained Follow-Up Attacks can perform well against waves of enemies.
  • Flexible Mortenax Blade: He also fits Acheron and other debuff-focused teams.

4.2 Weaknesses You Should Know Before Pulling

  • Survivability Issues: Without enough healing or damage mitigation, the team can struggle in high-pressure fights.
  • Expensive Team Core: Three limited 5-star characters make this lineup costly for newer and F2P players.
  • Rotation-Dependent: Losing field uptime or letting Ashveil's target mark expire can reduce team damage.
  • Overlapping Debuffs: DEF reduction can stack, but its total effectiveness depends on the combined debuffs and applicable limits.
  • Not Ideal for Every Fight: Against hard-hitting bosses, reliable sustain is often more valuable than maximizing FUA frequency.

Overall Verdict: The all-male FUA team is best for players with an established roster who enjoy fast, chained attacks. Prioritize core characters first, key Eidolons second, and signature Light Cones last.

Just a few pulls away from pity? If you're considering an HSR Top Up to get more Oneiric Shards, set a spending limit first. Don't let an E1 or signature Light Cone chase disrupt your plans for future banners.

Final Verdict: Should You Pull Mortenax Blade?

Mortenax Blade's Version 4.6 Phase 2 rerun is a great opportunity for players who already own Aventurine • Waveflair and Ashveil to complete their all-male Follow-Up Attack team.

E0S0 already provides his main utility, so there's no need to chase extra Eidolons or his signature Light Cone just to make the team functional.

If you love male characters and enjoy rapid-fire Follow-Up Attacks, this lineup is worth building.

However, if you care more about consistent endgame clears or you're short on Stellar Jade, improving your existing teams may offer better value than investing in three limited 5-stars.

Final Pull Recommendation: Already have Aventurine • Waveflair and Ashveil? Go for Mortenax Blade E0S0. Missing the core characters? Consider saving your pulls.

Good luck with your Warps, Trailblazers! May you win your 50/50 and complete your dream Follow-Up Attack team!

FAQ: Mortenax Blade & All-Male FUA Team

Q1: Can the all-male FUA team clear Memory of Chaos?

Yes, with sufficient investment and survivability. For tougher stages, use Luocha, Gallagher, or Dan Heng • Permansor Terrae as your sustain. If you don't mind changing the all-male lineup, Hyacine and Huohuo are strong alternatives.

Q2: Who should I pull first: Ashveil, Aventurine • Waveflair, or Mortenax Blade?

If your goal is to build this specific all-male FUA team, consider:

Ashveil (FUA Enabler) > Aventurine • Waveflair (Main DPS) > Mortenax Blade (Debuff Support)

This ranking is based on team-building priority, not overall character strength.

Q3: Does Mortenax Blade's field make the team too fragile?

His field mechanics involve HP consumption. Although his kit offers some defensive and recovery effects, they don't fully replace a dedicated sustain. A reliable healer is recommended for difficult endgame content.

Q4: Is Mortenax Blade E1 better than his signature Light Cone?

E1 is generally the better priority for players focused on field uptime and team utility. However, neither upgrade is required if you're satisfied with E0S0.

Q5: Is Mortenax Blade worth pulling without Aventurine • Waveflair or Ashveil?

If you already have Acheron or need additional Nihility debuff support, E0S0 can still be worthwhile. But if you're pulling only to build the all-male FUA team from scratch, it's better to consider the total investment first.
