Note for beginners

Mortenax Blade has no clear weak point based on current data, but needs the right build (see the Build section below) to reach full potential.

Should you pull Mortenax Blade?

Mortenax Blade is a hybrid between a 'reckless brawler' and a 'living shield': he burns his own HP to unleash massive AoE Fire damage across all enemies while also taunting them (forcing enemies to attack him instead of teammates) and cutting his own damage taken to protect the team.

Since he is brand new, this is an early assessment - a cautious 4/5: high potential but still needs more real-world verification.

Pros
  • Massive AoE damage (hits all enemies at once) that scales off Max HP, so you don't need to sink resources into an expensive ATK stat.
  • Self-taunts enemies and cuts 90% of damage he takes on entering combat - he tanks hits for the team while dealing damage, great for players worried about a 'fragile' team wipe.
  • His Ultimate weakens all enemies at once (lower DEF, higher DMG taken), so the whole team benefits from bigger numbers, not just him.
  • Has a built-in auto-loop: attack enough and he automatically unleashes a 420% Max HP AoE finisher, no complicated combo timing needed.
Cons
  • He constantly 'burns' his own HP to deal damage (losing 10-20% Max HP each time he uses his Skill or Ultimate) - without a solid healer, he can easily put himself in danger mid-fight.
  • He just released, so the community hasn't fully verified optimal numbers and team comps yet - everything here is an 'early assessment' and may change as more real data comes in.
  • There's no reliable Eidolon (character rank-up) data yet to recommend investing further copies right now - hold off on spending extra resources on his Eidolons for the time being.
  • His enhanced Basic ATK hits a single target while his enhanced Ultimate hits everyone - the alternating single-target vs AoE hits can be confusing for newer players tracking turn order.

How to play

Open with the Skill 'A Rain of Blades Seals Fate': it consumes 10% of his own Max HP and deals damage equal to 90% Max HP to all enemies, plus 4 extra instances each dealing 30% Max HP to a random enemy.

Once Energy is full, use the Ultimate 'Fornax Ex Corpore' to inflict 'Balefire Bind' on all enemies (reduces their DEF by 35% and increases DMG they take by 60% for 2 turns), then it consumes another 20% Max HP to deploy a Zone and enter an Enhanced State.

While enhanced, his Basic ATK becomes 'A Tempered Blade Severs Souls' (140% Max HP to one target plus Taunt).

Every ally attack landed on an enemy while the Zone is active grants 1 Charge via the Talent 'All Karma Comes Due'; once Charge hits 9 (with HP above 1), it auto-restores 30 Energy and unleashes the enhanced Ultimate 'Tenax Per Ignem' - a 420% Max HP nuke hitting all enemies, which is his main finishing move.

Stat targets

Because Mortenax Blade's damage scales off his own Max HP percentage instead of the usual ATK stat, stack HP% on the Feet and prioritize Fire DMG Boost on the Sphere. Use CRIT DMG% on the Body to hit harder on crits.

For the Rope, pick Energy Regeneration if his Ultimate feels slow to charge, or switch to HP% once Energy is comfortable. Substat priority: CRIT Rate > CRIT DMG > HP% > SPD > Effect RES (so he isn't easily crowd-controlled while tanking hits for the team).

Teams

Best teammates to pair with

Best teams for Mortenax Blade

Team 1 (premium, high investment): Mortenax Blade + Robin (team-wide ATK/CRIT buffs) + Ruan Mei (general DMG boost and enemy weaken) + Huohuo (healing plus SPD buff).

Team 2 (budget-friendly, easy to build): Mortenax Blade + Tingyun (ATK buff and Energy support) + Gallagher (shield plus healing) + Lynx (healing and emergency rescue) - great for newer players since Mortenax burns a lot of his own HP and needs steady healing.

Team 3 (debuff-stacking, weakens enemies): Mortenax Blade + Pela (DEF shred) + Jiaoqiu (extra Fire DMG amplification) + Bailu (healing).

All three teams need at least one dedicated healer, since Mortenax Blade constantly burns his own HP.

How far to invest, which milestones matter

Too new — community data is not settled enough for an Eidolon call. E0 is fine; do not rush copies before the meta stabilizes.

Skills & Traces

What to level first — tap each skill for details

Skill Leveling Priority

Ultimate ★★★★★ Ultimate both applies the team-wide "Balefire Bind" debuff (DEF down, DMG taken up) and serves as the massive AoE nuke Tenax Per Ignem scaling off Max HP, so it should be maxed first.
Talent ★★★★★ Talent sustains the Zone, reapplies Balefire Bind after every ally attack, and builds Charge to trigger extra Ultimate casts, making it just as important as Ultimate.
Skill ★★★☆☆ Skill deals HP%-scaling AoE DMG but costs the character's own HP, contributing extra output rather than being the core power source, so it sits at medium priority.
Basic ATK ★☆☆☆☆ Basic ATK only hits a single target and applies Taunt, unrelated to the core debuff/Zone loop, so it remains the lowest leveling priority.
Trace priority: A6 > A4 > A2 Eidolon priority: E6 = E4 > E1 = E2 > E3 = E5

Mortenax Blade FAQ

What is the best Light Cone for Mortenax Blade?

The best Light Cone for Mortenax Blade is In the Name of the World (top pick). See F2P options in the Light Cones section above.

Is Mortenax Blade worth pulling?

Mortenax Blade is a hybrid between a 'reckless brawler' and a 'living shield': he burns his own HP to unleash massive AoE Fire damage across all enemies while also taunting them (forcing enemies to attack him instead of teammates) and cutting his own damage taken to protect the team. Since he is brand new, this is an early assessment - a cautious 4/5: high potential but still needs more real-world verification.

What is the best team for Mortenax Blade?

Team 1 (premium, high investment): Mortenax Blade + Robin (team-wide ATK/CRIT buffs) + Ruan Mei (general DMG boost and enemy weaken) + Huohuo (healing plus SPD buff). Team 2 (budget-friendly, easy to build): Mortenax Blade + Tingyun (ATK buff and Energy support) + Gallagher (shield plus healing) + Lynx (healing and emergency rescue) - great for newer players since Mortenax burns a lot of his own HP and needs steady healing. Team 3 (debuff-stacking, weakens enemies): Mortenax Blade + Pela (DEF shred) + Jiaoqiu (extra Fire DMG amplification) + Bailu (healing). All three teams need at least one dedicated healer, since Mortenax Blade constantly burns his own HP.

How much Energy does Mortenax Blade's Ultimate cost?

Mortenax Blade's Ultimate costs 160 Energy. See the Skills section above for the Energy gain and Break DMG of every skill.

What materials does Mortenax Blade need to reach max Ascension?

See the full Ascension Materials list above, pulled directly from the latest game data.

How to read this build page

Every character build page has these parts: recommended Light Cone/Relic sets and stat table, a Trace/skill leveling order, Eidolon milestones worth considering, and a reference SPD threshold. Read them in that order — gear tells you "what to use", Traces tell you "what to level first", Eidolon tells you "is it worth pulling dupes", SPD tells you "how fast you need to be to keep the rotation on time". The section below explains how to read each part and applies the same way to every character on the site — check the exact numbers in the table above this section, since community sources sometimes differ by a few points.

Why the Light Cone and Relic picks make sense

Most characters have a "signature" Light Cone built for their exact role, plus a few cheaper substitutes from the standard banner or easy-to-get 3-4★ cones. Missing the signature isn't a dead end — most characters keep most of their power with a well-matched substitute, typically losing somewhere between a few percent and roughly a fifth of total damage depending on the setup, per most public comparisons.

  • Relic sets (2pc+2pc or 4pc) are picked for the set effect that fits that character's role (single-target DPS, AoE, shield/healing support, Break damage, and so on).
  • Main stats per slot (Body/Feet/Sphere/Rope) and substats follow a priority that changes by role: DPS roles usually chase CRIT Rate/CRIT DMG before ATK%; Break-focused roles prioritize Break Effect; support/healing roles often value Effect Hit/RES or Outgoing Healing over pure CRIT.

These weights differ per character and can shift slightly between ranking sources — follow the exact priority table above rather than applying one formula to every role.

Trace/skill leveling order by role (a general guideline, not a fixed rule)

There's no single order that's correct for every character, and community sources sometimes disagree depending on the team the character is used in — but the general pattern by role is:

  • DPS: level whichever skill (Skill or Ultimate) carries most of the damage for that character first, with Basic ATK usually last if it isn't the main damage source.
  • Support/Buffer: prioritize Traces that boost buff strength or the skill that applies the effect over Basic ATK, since this role's value comes from lifting the team rather than personal damage.
  • Healer/Shielder: prioritize the main healing or shield skill first, since that is the reason the team runs this character.
  • Break/CC: prioritize whichever skill contributes the most Toughness Damage, since the Break/Weakness Break window is where the team dumps damage.

Major Traces unlock at fixed ascension levels in-game, not by choice — but which one to level first (when resources are limited) should follow the role priority above. Since the exact order can differ between ranking sources, check the specific recommendation in the table above for this character.

Eidolons: how far E0 gets you, and which milestone is worth considering

General rule: most characters at E0 (no duplicates) already handle most content, even 5-star characters. Eidolons are a duplicate-fueled upgrade system — higher levels cost more resources for a smaller power gain, and the actual gain varies a lot per character (some barely change role at E0, others shift how they're played at a specific level). The milestones most often cited by the community tend to sit at E1, E2, or E6 depending on the character — but none of these are required to clear the game's content. Check the Eidolon section in the table above for this character's specific milestone and gain; if sources disagree on how to rate a milestone, trust the in-game effect description over a pre-set percentage number.

How to think about SPD breakpoints

SPD (Speed) controls how often a character acts in the turn order — higher SPD means denser actions, and for some roles (especially support/healing that need to buff or heal before the team gets hit) hitting the right SPD "breakpoint" matters more than the raw SPD number. Values like 101 or 134 SPD are often cited as community-common breakpoints (letting a character act again before or after a specific point in certain team setups) — this is crowd-verified action-gauge math, not an official fixed number the game states for every situation. The right breakpoint also depends on the team and allies' SPD, so treat the SPD suggestion in the table above as a starting point to adjust from, not a mandatory target.

Where to dig deeper

This section only teaches you how to read the page — for deeper comparisons, use the dedicated tools:

  • Tier list to see where this character stands against the full roster.
  • Teams for full in-game comps with rotation order.
  • Relic score to check how your current gear scores against the benchmark.
