Sephiria Katana – Weapon Overview, Stats, and Builds

Learn about the Sephiria katana, its base stats, enhancement paths, and how to build around it in this action roguelite.

The Sephiria katana is a weapon class in the action roguelite Sephiria. It is a fast, medium-range weapon that rewards aggressive play with a unique stance system that includes a lead (sheathed) and drawn state. This page covers the katana's base stats, enhancement paths, how to obtain it, and its role in common builds.

Overview

The katana is one of six weapon types available in Sephiria as of the early access period. It features a 3-hit basic attack combo with medium stiffness and a special attack that changes depending on whether the blade is sheathed (lead) or drawn.

Players who prefer a hit-and-run style often use the katana's dash attack, which has a short motion and can be woven between normal attacks for faster damage output. The weapon also grants a brief invincibility window when switching between lead and drawn states, which can be used to avoid enemy attacks.

The following table summarizes the katana's base damage coefficients and activation coefficient. All values are taken from the game's weapon enhancement documentation.

How to Obtain

The katana is a weapon that players can unlock and select during a run. According to player reports, the katana is unlocked after a certain point in the game's progression; it was not available from the start in early access. Once unlocked, it can be chosen as the starting weapon or found during a run, similar to other weapons in the game.

The exact unlock condition has not been verified from the available sources.

Enhancement Paths

Each weapon in Sephiria can be enhanced up to two times. The second enhancement builds on the first, and the player chooses between two different upgrade paths at each stage. The katana's enhancement tree includes several options, each suited to a different playstyle.

Helbanus (Fire Attribute Path)

  • Helbanus (Primary): Weapon attacks deal additional fire damage equal to 30% of the damage dealt.
  • Seething Helbanus (Secondary): Increases burn stack limit by 2 and fire attribute damage by 4.
  • Heidi (Secondary): Consuming a dash count grants an Overheat stack (up to 6). Overheat sets attack speed to 300% and changes normal attacks to fire-based damage (110% of fire attribute damage).
  • Solis Eckley (Secondary): Changes lead to Eclipse. Eclipse consumes up to 10 Sun Swords to grant a 10-second buff that adds fire damage equal to 70% of fire attribute damage to weapon attacks, applies Sun Sword bonuses to normal attacks, and increases weapon damage by 10% per Sun Sword consumed.

Geomchamdo Path (Normal Attack Builds)

  • Geomchamdo: Cheon Gwang-sak (Primary): Normal attacks build Sword Gauge. Special Attack: Strong Slash is replaced with Normal Attack: Iahap Slash, which deals 200% physical damage. When the gauge is full, Iahap Slash becomes Dagger Clash, dealing 400% physical damage with a wider range.
  • Geomchamdo: Biryu (Secondary): Increases critical chance by 30% and changes Dagger Clash to hit the entire screen.
  • Geomchamdo: Pamu (Secondary): Seals Dagger Clash but grants a Rampage buff when the gauge is full. Rampage changes normal attacks to a 4-hit combo with additional damage (75% physical damage) between hits.

Other Enhancement Paths

  • Attitude 'Onohara' (Primary): Increases attack speed by 15% and makes Strong Slash scale with attack speed.

    • Myeongdo 'Muramasa' (Secondary): Keeps the blade permanently in lead state, changes Strong Slash to Quick Slash, which costs no MP but reduces weapon attack damage by 30%. Increases attack speed efficiency by 80%.
    • Gokdo 'How' (Secondary): Strong Slash becomes a ranged, multi-hit attack that scales with evasion (1% damage per 2 evasion). Attack speed is reduced by 24%.
  • Winter Blacksmith's Study (Primary): Changes lead to Tackle, a dash that grants invincibility and costs 5 MP. Weapon attacks deal additional ice damage equal to 15% of ice attribute damage, and ice attribute damage is increased by 3.

    • Silence of the Perennial Snow (Secondary): Changes Tackle to Ice Sliding, which deals 50% ice damage to enemies touched. Blocking an attack during the invincibility window triggers the Echo of the Glacier artifact.
    • Fragment of Nastrond (Secondary): Attacking after a Tackle triggers Ice Arm: Skadi, which deals 25 + 175% ice attribute damage to nearby enemies (4-second cooldown).
  • Lightning Bronte (Primary): Reduces weapon attack damage by 20% but changes damage to scale with lightning attribute damage.

    • A Flash of Light (Secondary): Inflicting electric shock damage grants a stack of Storage (max 10). Special Attack: Strong Slash consumes 2 stacks to cast Flash, which deals lightning damage that scales with the target's electric shock stacks.
  • Cutlassfish (Primary): Normal attack damage increases by 1% per 2 defense.

    • Pagap Island (Secondary): While not in lead state, gain a stack of Hardening every 0.8 seconds (max 10). Each stack grants +1 defense. At max stacks, normal attacks deal bonus damage scaling with defense, and leading with 10 stacks fires a shock wave that consumes one stack.

Uses

The katana's enhancement paths support several distinct playstyles:

  • Fire/Burn Builds: The Helbanus path is the most popular for fire builds. Players can choose between the Overheat mechanic for burst damage or the Eclipse buff for sustained Sun Sword damage. A common strategy involves using the lead state to generate Overheat stacks and then unleashing them with normal attacks.

  • Normal Attack Builds: The Geomchamdo path focuses on building the Sword Gauge through normal attacks and then releasing powerful finishers. This build benefits from attack speed and critical chance.

  • Evasion/Shadow Builds: The Gokdo 'How' enhancement scales damage with evasion, making it a natural fit for builds that stack the Shadow stat. This playstyle emphasizes dodging and repositioning over tanking damage.

  • Ice Builds: The Winter Blacksmith's Study path converts the katana into an ice weapon with a focus on mobility and frostbite application.

  • Defense Builds: The Cutlassfish path rewards players who invest in defense, turning the katana into a tankier option.

Version Context

Sephiria is in early access. The katana's enhancement tree has been updated over time, with some paths added or adjusted in specific patches. For example, the Winter Blacksmith's Study path received an additional ice damage effect in update 0.8.13, and the Cutlassfish path was added after patch 0.11. As of the last check, the game has six weapon types, and the katana is one of them.
