Quasimorph Eclipse Blades Class Guide
Melee dominance through door peeking, carnage stacking, and infection immunity
Eclipse Blades is Quasimorph’s flagship melee class — a high-risk, high-reward kit that rewards positioning knowledge, patience, and clone management over raw firepower. The class peaks in chokepoint-heavy mission types like Conquest and Sabotage, where door tiles become turn banks and multiple enemies file through predictable entry points. This guide covers Eclipse Blades mechanics, perk priorities, operator synergy, and the door-peek loop that defines competitive melee play after the 1.0 launch.
Eclipse Blades class overview
Eclipse Blades specializes in close-quarters melee dominance with perks that amplify series-of-hits weapons, grant accuracy bonuses while moving, and convert kills into stacking damage buffs called carnage. The class ships with a base kit that rewards aggressive positioning through doorways and corridors where multiple enemies must path single-file.
Core strengths:
- Highest single-turn damage potential in the game when carnage stacks align
- Series-of-hits melee weapons proc multiple times per action, multiplying buff effectiveness
- Infection immunity via Isabella Capet pairing removes the need for sorbets
- Low ammo weight allows heavier medkit and food loads
Core weaknesses:
- Dies quickly in open Defence arenas without cover
- Calorie consumption spikes when sprinting between doors
- Cannot handle ranged-only encounters without a cut sidearm
- Quasimorphosis events force retreats or fights in bad geometry
Perk breakdown and priorities
Eclipse Blades perks fall into three tracks: accuracy and evasion, carnage amplification, and cannibalism conversion. Prioritize carnage track first, then accuracy for consistency.
Carnage track (priority 1)
Carnage — Each kill within 4 tiles grants a stacking buff that increases melee damage. At 3 stacks, Eclipse Blades damage output rivals heavy gunners. At 5+ stacks, a single door peek can eliminate elite targets.
- Stack management matters more than raw damage numbers
- End fights before stacks decay (stacks persist 2 turns after last kill)
- Pair with sprint positioning to maintain proximity after kills
Carnage Boost (upgrade) — Increases maximum carnage stacks and extends duration. Required for endgame Eclipse viability.
Carnage Surge (capstone) — Grants temporary action point refund on high-stack kills. Enables double-door plays in Sabotage objectives.
Accuracy and evasion track (priority 2)
Blade Precision — Increases melee accuracy, reducing whiffed attacks on sprint-open doors. Accuracy loss while moving is the most common source of early Eclipse failures.
Opportunist — Grants bonus accuracy against enemies who just moved. Useful when enemies patrol into your door tile rather than charging.
Dodge Reflexes — Adds evasion while unencumbered. Eclipse Blades naturally stays light; this perk leverages that constraint.
Cannibalism track (priority 3)
Cannibalism — Converts remaining food calories into damage buff after kills. Isabella Capet operators ignore infection from raw meat consumption, making this track free damage for her builds.
Metabolic Overdrive (upgrade) — Extends cannibalism window and reduces calorie conversion penalty. Useful in long Sabotage clears where food supply is limited.
Feast (capstone) — On-kill calorie restoration. Reduces food dependency between extractions and enables marathon door-clearing sessions.
Best operators for Eclipse Blades
Isabella Capet (best overall)
Isabella Capet is the premier Eclipse Blades operator. Her infection immunity removes the raw meat infection penalty that would otherwise cripple cannibalism track effectiveness. She provides:
- No infection from raw meat, enabling unlimited cannibalism procs
- Low-health damage scaling that synergizes with Eclipse’s risk-reward playstyle
- Moderate accuracy base that Blade Precision elevates to reliable levels
Recommended starting clone build: Prioritize health and accuracy traits. Dodge is secondary — Eclipse Blades wins through burst, not attrition.
Kenzi (dodge alternative)
Kenzi offers high base evasion, creating a glass-cannon Eclipse variant that dodges through patrols rather than facetanking. This build sacrifices some carnage uptime for safety in open stations.
Best for: Players transitioning from Scouts who prefer mobility over burst.
Percy Paladin Fawcett (tank pairing)
Percy’s universal tank perk makes him a safe Eclipse pilot for first clears. He absorbs one mispositioning mistake per mission — valuable when learning door geometry.
Best for: New Eclipse players learning door-peek timing.
Door peek mechanics and positioning
Door peeking is the foundational Eclipse Blades technique. It transforms doorways from simple transitions into turn banks where you control which enemy enters your attack range first.
Basic door peek loop
- Sprint to a door tile adjacent to an enemy path
- End turn on the door tile in Sprint stance
- Enemy pathing AI enters the doorway one-by-one
- Attack with series-of-hits melee as each enemy enters range
- Carnage stacks accumulate with each kill
- Use accumulated carnage for high-value target removal
Advanced door geometry
Corner doors — Position at hallway intersections where two doorways meet. This lets you threaten two angles simultaneously and retreat if one direction goes wrong.
End-cap doors — Doors at dead-ends are safest Eclipse positions. Enemies must enter single-file with no retreat angle for them.
Stairwell tiles — Vertical movement tiles create predictable entry points. Learn which stations have stairwell chokepoints and pre-position before patrol routes cycle.
Sprint stance accuracy penalty management
Sprint grants 3 actions but imposes accuracy penalty. Eclipse Blades perks reduce this penalty, but players should:
- Use Blade Precision perk to close the accuracy gap
- Attack enemies at 2-tile range rather than maximum melee range
- Pre-buff with cannibalism before opening contested doors
- Accept that some Sprint attacks will miss — plan for 80% hit rate
Weapon recommendations
Early game (Mars zones)
Jackhammer — Found early, reliable series-of-hits pattern, good cut damage for robot floors. Carries players through first Mars contracts without craft investment.
Claw knives — Light weight, fast series-of-hits, decent cut profile. Upgrade path from Jackhammer to crafted blades.
Mid game (Phobos, Deimos, Tezctlan stations)
Crafted machetes — Best bang-for-buck cut weapons. Craft from components disassembled at bench. Prioritize cut damage and series-of-hits pattern.
MPL-95 — High-end crafted option with excellent series-of-hits and cut profile. Hoard components from Mars farming runs.
Endgame (Absence zones, RealWare, outer system)
Varangian — Top-tier crafted blade with maximum series-of-hits and cut damage. Requires endgame bench tech and rare components.
Macuahuitl — Alternative endgame option with slightly different pattern. Choose based on bench recipe availability.
Backup ranged weapon (mandatory)
Always carry a cut shotgun or pistol for:
- Cutters and flamethrower enemies who close faster than melee range
- Ranged-only encounters in open rooms
- Quasimorphosis events where positioning breaks down
Consumables and loadout
Required items
- Medkit — Primary panic heal. Stabilizes wounds for extract.
- Bandages or splints — Efficient mid-fight patching without medkit waste.
- Food — Raw meat from mission loot. Isabella Capet ignores infection.
- Cut sidearm — Backup ranged for emergencies.
Optional items
- Sorbets — Not needed with Isabella Capet. Other operators require 1-2 for infection control.
- Deployable cover — Niche use in open Defense missions. Generally skip for Eclipse.
- Timer reducers — Required on timed missions from Walkthrough Hub.
Loadout example
Primary: Crafted machete (series-of-hits, cut) Backup: Cut shotgun Medkit: 2x Bandages: 3x Food: Raw meat stack (Isabella ignores infection) Cut sidearm: Compact pistol Weight target: Under 70% carry capacity
Mission type suitability
| Mission type | Eclipse viability | Notes |
|---|---|---|
| Conquest | Excellent | Chokepoints, door geometry, multi-kill potential |
| Sabotage | Excellent | Objective rooms create natural door banks |
| Espionage | Good (with cut sidearm) | Quiet melee, but ranged sections need backup |
| Defence | Poor | Open arenas, no door geometry, ranged pressure |
| Extraction | Good | Natural chokepoints, but timers matter |
Carnage management and stack decay
Carnage stacks decay 2 turns after your last kill. Managing decay is critical for extended missions:
High-stack plays (5+): Save for elite targets. Door peek, build to 5 stacks on trash, then delete a Commander or Baron with full carnage.
Stack maintenance: In long corridors, kill frequency determines carnage uptime. Position to maintain 2-3 stacks between elite encounters.
Emergency stack rebuild: Retreat to a side room, let patrol respawn, re-engage. This resets enemy density without full mission restart.
Common mistakes and fixes
Mistake: Sprint attacking into full rooms
Opening a Sprint attack into a room with 4+ enemies means you hit one, eat 3 overwatch reactions, and die. Fix: Single-door peek only, let enemies file in.
Mistake: Ignoring cut sidearm
Entering a station with no ranged backup means cutters and flamethrowers delete you before melee range. Fix: Always pack cut pistol or shotgun.
Mistake: Over-farming carnage before extract
Extended mission time raises Quasimorphosis meter, increasing horror spawns. Fix: Set carnage threshold (3-4 stacks), extract on objective completion.
Mistake: Using Isabella without infection immunity knowledge
Raw meat is free damage with Isabella, but players sometimes waste calories on full-health clones. Fix: Save cannibalism for post-kill low-health situations.
Eclipse Blades versus other melee classes
Phoenix Brigade — Less burst, more sustain. Better for drawn-out Defence missions. Eclipse wins in burst; Phoenix wins in attrition.
Tunnel Rats — Economy-focused kit. Eclipse outdamages in combat; Tunnel Rats outpaces in loot extraction. Different goals, not direct competitors.
