BUILD REPORT

“Ghost Blade”

This build weaponizes the Assassin's Active Camo and smoke toolkit to close distance undetected, deliver a devastating Knife strike from invisibility, then vanish back into a fresh smoke field before the target's crew can react. Every item chosen tightens the gap between approach, kill, and exfil — the Knife is the anchor, Active Camo is the delivery mechanism, and smoke is both your approach vector and your escape hatch.

A

LOADOUT GRADE

RANKED VIABLE

Weapons

Knife

PRIMARY

80 damage per swing at CQB range is the highest single-hit melee damage in the database, and with Shadow Strike equipped it deals greatly increased damage from invisibility — making it a near-guaranteed down on isolated targets from a clean backstab approach. No ammo dependency means zero logistical overhead on a solo runner.

Magnum MC

SECONDARY

41 damage per shot at Mid range with 138 RPM fills the engagement bracket the Knife cannot reach. When a target breaks contact past CQB range or you need to punish a fleeing runner before they can rally, the Magnum MC's per-shot output keeps pressure on without requiring sustained mag dumps that would burn your repositioning window.

Weapon Mods

CHIP

See Ya (Superior)

Reloading the Magnum MC on an empty magazine causes you to briefly go invisible — directly extending Active Camo's disruption window or re-establishing concealment mid-fight after a kill. On a solo flanker this is a second escape valve that costs nothing beyond a reload timing discipline.

CHIP

Cloudborn (Enhanced)

The Assassin is permanently inside or adjacent to smoke — Shadow Dive and Smoke Screen both generate fields you will be standing in. Cloudborn grants increased stability, accuracy, handling, and movement speed while in smoke, making every engagement window inside your own deployed fields a stat-buffed scenario at no additional resource cost.

BARREL

Steady Barrel (Superior)

Greatly increases stability, ready speed, and accuracy while moving — critical for the Magnum MC since flanking approaches are made at sprint or crouch-walk speed. Pulling the Magnum while closing on a secondary target needs to be instant and on-target, and this barrel ensures the transition from knife to sidearm doesn't cost you the window.

OPTIC

Oracle Lens (Superior)

Greatly increases ADS speed, accuracy while moving, and ADS accuracy — the Magnum MC's 138 RPM means every shot must land, and this optic ensures that mid-repositioning ADS snaps are tight. Synergizes with the constant-movement discipline of a flanking build.

Shell Cores

Shadow Strike (Prestige, Passive, Meta Rating: S)

PASSIVE

This is the build's load-bearing core. It directly multiplies Knife damage when attacking from invisibility — Active Camo is a 15-second window specifically designed to get you behind a target, and Shadow Strike turns that approach into a near-instant elimination. S-tier meta rating is justified: no other core converts the Assassin's stealth uptime into raw kill efficiency at this level.

Safe Landings (Deluxe, Passive, Meta Rating: A)

PASSIVE

Shadow Dive is a vertical flanking tool and repositioning escape — Safe Landings causes the landing to knock nearby hostiles away and creates a longer-lasting smoke field. This extends your post-dive concealment window significantly beyond the base 4-second dissipation, giving you time to reset Active Camo or execute a follow-up Knife strike without being immediately re-acquired.

Guerrilla (Superior, Passive, Meta Rating: B)

PASSIVE

Active Camo and Shadow Dive recharge faster while you are inside smoke — and this build generates smoke constantly between Smoke Screen, Shadow Dive, and Safe Landings' extended fields. On a solo runner with no support, keeping Active Camo cycling tightly is the difference between a repeatable flanking pattern and a one-shot gimmick.

Implants

HEAD

Sprint Kit V2 (Enhanced)

Loot Speed: 10%, Agility: 10, Fall Resistance: 10%

Agility: +10 directly improves the movement speed that makes flanking viable — every tick of extra sprint speed tightens the gap during Active Camo's 15-second window. The passive Tox Injectors applies Toxin on knife heavy attacks, adding a damage-over-time component that pairs with Shadow Strike for even more punishing opener damage. Fall Resistance supports Shadow Dive re-entries.

TORSO

Knife Fight V4 (Superior)

Hardware: -10, Melee Damage: 50, Fall Resistance: 20%

Melee Damage: +50 is the single largest melee damage modifier in the torso slot, directly amplifying the Knife's 80-damage base further when combined with Shadow Strike's invisibility bonus. The Escape Artist passive — removing hostile pings when your shield breaks — is a solo survival mechanism that denies enemy crews a read on your position exactly when you're most exposed. Hardware: -10 is accepted as the trade-off.

LEGS

Graceful Landings V4 (Superior)

Melee Damage: 20, Agility: 20, Fall Resistance: 50%

Melee Damage: +20 stacks on top of Knife Fight V4's +50, pushing the Knife's effective damage output significantly higher before Shadow Strike's multiplier is applied. Agility: +20 is the highest confirmed Agility value in the legs slot, maximizing flanking approach speed. The Frenzy Matrix passive — increased tactical recharge rate and sprint speed after a kill — means each successful Knife elimination feeds the next Active Camo cycle faster.

◇ Assassin Cradle Build — Season 2 Stat Plan

Free respec · resets each season

Double down on Strength to maximize Knife lethality through the full perk chain, then invest in Recharge to keep Active Camo and Shadow Dive cycling fast enough to sustain a solo flanking tempo.

STRENGTH TRACK

6 ENERGY

PERK · Finisher Protection

First breakpoint — take less damage while performing finishers, which are frequent on a Knife build that regularly closes to melee range. Keeps the aggressive play pattern from being punished mid-execution. Note: exact values are source-listed as unconfirmed.

STRENGTH TRACK

11 ENERGY

PERK · Close & Personal

Melee and knife attacks generate less heat — critical because the Assassin's Active Camo and Patience core both generate heat, and chaining Knife strikes inside that window compounds heat buildup. This perk keeps the attack chain sustainable. Note: exact values are source-listed as unconfirmed.

STRENGTH TRACK

14 ENERGY

PERK · Leech

Knife attacks restore a small amount of health — on a 120 HP shell with no shield and Hardware: -10 from implants, passive in-combat sustain from every Knife swing is directly valuable. Full Strength track investment at 14 Energy. Note: exact values are source-listed as unconfirmed.

RECHARGE TRACK

4 ENERGY

PERK · Head Start

Start runs with partial Tactical charge — Active Camo comes online faster at drop, enabling an aggressive early-game flanking window before other runners have established positions. Note: exact values are source-listed as unconfirmed.

RECHARGE TRACK

14 ENERGY

PERK · Lethal AMP

Downing a Runner grants Tactical energy and eliminating grants Prime energy — every Knife kill directly feeds the next Active Camo charge and accelerates Smoke Screen availability. This closes the loop on the solo flanking cycle: kill, recharge, re-cloak, repeat. Note: exact values are source-listed as unconfirmed.

STRENGTHS

+Shadow Strike + Knife Fight V4 (Melee Damage: +50) + Graceful Landings V4 (Melee Damage: +20) stack massive melee damage multipliers on the Knife's 80-damage base before Shadow Strike's invisibility bonus is even applied — making opening strikes catastrophic for isolated targets

+Active Camo (15s) + Guerrilla core + Frenzy Matrix passive (from Graceful Landings V4) creates a tightly cycling ability loop where kills directly feed the next cloak window, sustaining the flanking pattern across multiple engagements

+Safe Landings + Ghost Protocol-extended smoke fields + Cloudborn mod turn every Smoke Screen or Shadow Dive into a extended concealment zone that buffs your own weapons — your escape routes are also your combat advantage zones

WEAKNESSES

−Knife Fight V4 and Sprint Kit V2 impose a combined Hardware: -20 penalty on a shell that already has only 120 base HP and no shield — any failure to land the opener or disengage cleanly exposes an extremely fragile runner to lethal return fire

−Effective engagement range is almost entirely CQB; the Magnum MC covers mid-range emergencies but its 12-round mag and 138 RPM punish missed shots, and long-range engagements are simply unwinnable — map positioning discipline is mandatory

RANKED NOTE

This is a casual build with no rank constraints — it's optimized for effectiveness and fun at the experienced level, not score thresholds, so no holotag tier target is assigned.

⬢ Build Analysis

Ghost Blade is what happens when you stop treating the Knife as a gimmick and start treating it as a precision instrument. Shadow Strike is the S-tier reason this build exists — it converts Active Camo's 15-second window from a reposition tool into a damage multiplier, and stacking Knife Fight V4's confirmed Melee Damage: +50 with Graceful Landings V4's confirmed Melee Damage: +20 on top of the Knife's 80 base damage means your opener from invisibility is hitting at a number that drops most targets before they process what happened. Guerrilla keeps Active Camo and Shadow Dive recharging inside your own smoke fields, and Safe Landings extends Shadow Dive's smoke from 4 seconds to a meaningfully longer window — enough to reset camo or execute a follow-up. The Recharge track's Lethal AMP perk (source-listed, unconfirmed) closes the kill-to-recloak loop, meaning each elimination is also an ability refund. See Ya on the Magnum MC gives you a second brief invisibility pulse on mag dump, which is a genuine mid-fight escape that costs nothing but reload timing. Cloudborn in smoke, Frenzy Matrix after a kill — every system feeds the next. The Hardware deficit is real and the margin for error is thin, but that's the Assassin's contract.
