BUILD REPORT

“Ghost Dividend”

Ghost Dividend is a free-loadout scavenger rig built entirely around Rook's zero-risk drop profile: you move fast, loot faster, and exit clean before anyone knows you were there. Signal Mask is your primary engagement tool — use it to ghost past UESC patrols and Runners alike, while Recuperation buys you recovery windows between loot pulls without burning consumables.

A

LOADOUT GRADE

Weapons

M77 Assault Rifle

PRIMARY

At 16 damage, 450 RPM, and a 24-round Light Rounds magazine with Flex range coverage, the M77 covers both close hallways and mid-range open zones without requiring ammo type swaps. Its Flex range rating means you are never caught in an unfavorable bracket during unplanned encounters, and Light Rounds are the most commonly scavenged ammo type on the map — critical for a shell that lives off the floor.

KKV-9SD

SECONDARY

At 9 damage per shot and 1200 RPM with a 28-round Light Rounds magazine, the KKV-9SD is a lightweight pistol slot option that shares Light Rounds with the M77, preventing ammo competition. It fills the pure CQB panic role if Signal Mask drops unexpectedly at close range, and its high fire rate means short-duration burst fights — the only fights a Rook should be taking — can be resolved before the engagement escalates.

Weapon Mods

CHIP SLOT

Scrapyard Chip (Superior)

Directly amplifies Rook's core scavenger identity: defeating hostiles has a chance to spawn depleted health items or standard materials, generating passive loot economy from any mandatory combat. On a free-loadout shell where every recovered item is pure profit, this chip converts even reluctant fights into loot events.

OPTIC SLOT

Oracle Lens (Superior)

Greatly increases ADS speed, accuracy while moving, and ADS accuracy. On a scavenger shell that prioritizes repositioning and disengagement over held positions, the movement-accuracy bonus means you can take snap shots while retreating without losing effective damage, and the ADS speed increase tightens the window between spotting a threat and responding.

BARREL SLOT

Steady Barrel (Superior)

Greatly increases stability, ready speed, and accuracy while moving. The ready speed component directly compresses the weapon-swap overhead when emerging from a loot animation, and movement accuracy stacks with the Oracle Lens bonus — meaning this Rook can stay mobile during engagements rather than planting to fight.

MAGAZINE SLOT

Interval Mag (Prestige)

A custom M77 prestige mag that sources list as increasing range, magazine size, and reload speed, with reported stats of ads_spread -0.14 and aim_assist +0.05. The aim assist gain tightens tracking during the mobile, unstable engagements this shell generates, and a larger magazine reduces mid-loot reload exposure. Note: exact stat values are source-listed, not in-game confirmed.

Shell Cores

The Big Score (Standard, Universal)

PASSIVE

After opening a locked door or container, Loot Speed is temporarily greatly increased. Rook already has the highest loot speed of any shell — stacking a temporary burst on top of that after every locked container interaction means high-value rooms are cleared faster than any other shell configuration can achieve. This is the signature Rook core: it turns the act of looting into a self-reinforcing speed loop.

Cash Flow (Standard, Unknown)

PASSIVE

Opening an unlooted container pings a nearby data card. On a map-knowledge and credits farming run, this is a passive minimap that chains loot locations together — each container opened reveals the next high-value item. For an experienced Rook runner learning spawn patterns and data card locations, this converts loot pulls into cartographic intelligence.

Implants

HEAD

Sprint Kit V2 (Enhanced)

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

All three stats serve Rook's scavenger loop directly. Loot Speed 10% stacks multiplicatively with Rook's native loot speed advantage and The Big Score activation. Agility 10 improves traversal and repositioning speed between loot nodes. Fall Resistance 10% reduces the HP cost of vertical shortcuts through the map — relevant on a 120 HP shell with no shield.

TORSO

Nimble Fingers V2 (Enhanced)

Loot Speed: 25%, Agility: 5

Loot Speed 25% is the single largest loot-speed implant value available at confirmed Enhanced rarity in the torso slot. Combined with Sprint Kit V2's 10% and Rook's native bonus, this creates a dramatically compressed loot animation window. The passive Ballistic Resistance further reduces incoming UESC ballistic damage — meaningful on a 120 HP no-shield shell that cannot afford to trade hits.

LEGS

Graceful Landings V2 (Enhanced)

Agility: 10, Fall Resistance: 20%

Agility 10 stacks with head slot Agility 10 for a combined +20 Agility baseline, pushing movement speed and repositioning to the level where Signal Mask disruption from sprinting becomes less punishing — you get back into position faster. Fall Resistance 20% is the highest confirmed value in the Enhanced leg tier and directly enables aggressive vertical routing that other shells cannot safely use.

◇ Rook Cradle Build — Season 2 Stat Plan

Free respec · resets each season

Primary investment in Dexterity for Loot Speed and Agility gains that compound Rook's native scavenger advantage, with a secondary line in Resistance to extend survivability on a 120 HP no-shield shell.

DEXTERITY TRACK

5 ENERGY

PERK · Loot Siphon

Opening unlooted containers is Rook's primary action every run — sources list this perk as granting Tactical energy on each unlooted container open, which means Signal Mask recharges passively through the loot loop itself. Every chest pulled is an ability battery refill. Note: effect is source-listed unverified.

DEXTERITY TRACK

11 ENERGY

PERK · Slider

Sprint sliding generating less heat directly enables the high-mobility traversal routing Rook uses to cover ground between loot nodes quickly. On a shell with no shield, reducing heat accumulation from movement keeps the heat bar available as a buffer. Note: effect is source-listed unverified.

DEXTERITY TRACK

14 ENERGY

PERK · Full Throttle

Gaining Cardio Kick effects at run start means every drop begins with accelerated movement — compressing the critical early-loot window before Runners begin rotating. For a scavenger shell, first-loot priority is a primary edge. Note: effect is source-listed unverified.

RESISTANCE TRACK

3 ENERGY

PERK · Scab Factory

Bleeding out more slowly when downed is the highest-value early Resistance perk for a solo 120 HP no-shield shell. With no teammate to revive and no shield to absorb burst damage, extending the bleed-out window is the only solo self-rescue mechanic available. Note: effect is source-listed unverified.

RESISTANCE TRACK

14 ENERGY

PERK · Field Medic

Medical consumables taking less time to use directly accelerates Recuperation's ground-state healing and shortens the animation vulnerability window when patching mid-run. For a solo scavenger using consumables as the primary sustain mechanism, faster application means fewer situations where a patrol catches you mid-heal. Note: effect is source-listed unverified.

STRENGTHS

+Stacked loot speed from Nimble Fingers V2 (25%), Sprint Kit V2 (10%), The Big Score burst activation, and Rook's native loot advantage creates the fastest container-clear profile in the game

+Combined Agility +20 from implants alone (Graceful Landings V2 + Sprint Kit V2 + Nimble Fingers V2) enables aggressive vertical routing and fast repositioning after Signal Mask breaks

+M77 and KKV-9SD share Light Rounds, the most abundant floor ammo — a free-loadout shell never runs dry on a shared-ammo two-weapon configuration

WEAKNESSES

−120 HP with no shield means a single undetected Runner engagement or patrol volley can end the run before Recuperation stabilizes — Signal Mask discipline is non-negotiable

−Build has no direct combat damage amplification; in forced fights against geared Runners, the M77's 16 damage at 450 RPM is serviceable but not dominant — disengage is always the correct play

RANKED NOTE

Rook cannot be selected in ranked by design — this build targets unranked casual play exclusively and carries no ranked score implications.

⬢ Build Analysis

Ghost Dividend is built around one principle: Rook's free-loadout guarantee means the cost of a bad engagement is zero, but the cost of a slow loot pull is opportunity. So we invert the typical build logic — instead of arming up to fight, we arm up to vanish and vacuum. The Nimble Fingers V2 torso (Loot Speed 25%) combined with Sprint Kit V2 head (Loot Speed 10%, Agility 10) and The Big Score core creates a loot-speed cascade that no other shell can replicate. Cash Flow then chains containers to data card pings, turning each loot pull into a breadcrumb trail. The M77 Assault Rifle earns its slot through Flex range coverage and Light Rounds sharing with the KKV-9SD — two weapons, one ammo type, maximum floor-loot compatibility. Scrapyard Chip converts any mandatory kill into a material spawn, keeping the economy loop intact even when Signal Mask fails. Graceful Landings V2 legs add Fall Resistance 20% to unlock vertical shortcuts that compress rotation time. The Dexterity Cradle path to Full Throttle means every drop opens hot with Cardio Kick active — that's first-node loot priority, secured before anyone else hits the floor.
