Do do that voodoo that you do so well.

This review was machine-translated from the Japanese original. Numbers are checked against the original; if the wording reads oddly, the Japanese version is authoritative.

Ordnance (grenade type) puts enemies into Jinxed (cursed) state, and killing that enemy accelerates Ordnance cooldown, a grenade spin specialization class MOD. Shoot → curse → kill → can shoot again immediately, loop to keep Ordnance rolling, a sheet for C4SH.

🧩 Source of red text Cole Porter’s 1929 song “You Do Something to Me” includes the line “Do do that voodoo that you do so well” as the source. The phrase became famous when quoted by Hedley Lamarr in the film ‘Blazing Saddles’ (Blazing Saddles, 1974). “voodoo (witchcraft)” is tied to this MOD’s unique effect that puts enemies into Jinxed (cursed) state. It is (unverified) which direct path from the band/film was taken.

What kind of class MOD? (Beginner’s perspective)

• C4SH (Rogue / Rogue lineage) exclusive Legendary class MOD
• Theme is Ordnance (grenade type) spin enhancement
• Enemies hit by Ordnance Damage become Jinxed (cursed) state
• Killing a Jinxed enemy grants +20% Ordnance Cooldown Rate (12-second duration)
• This effect stacks up to max 10Stack = the more you kill, the faster you can fire Ordnance
• Exclusive status +29% Ordnance Cooldown Rate (raises CD speed from base) = core of Ordnance rapid-fire build

Unique Effects (Mechanics)

The exclusive status +N% is a level-dependent reference value (added 2026-08-06) The +N% below originates from Lootlemon / MentalMars. In-game, the exclusive status numbers change with Lv (the only fixed aspect is the status type (type), not the numbers).

• Measured: duration and damage categories are Lv45 = +41% / Lv47 = +43%. Other MODs / other VHs have the same values at the same Lv (not dependent on individual rolls or prefixes) = provisional formula value% = Lv − 4
• Using this formula, the Web’s +45% is written as a fixed value equivalent to Lv49
• ⚠️ Whether numbers from other categories such as +23% / +60% follow this formula is (unverified) (Cooldown rate may be Lv-independent, being +23% at Lv45/47)

Cooler: Ordnance Damage makes enemies Jinxed. Jinxed enemy kill grants +20% Ordnance Cooldown Rate (12 seconds, up to 10Stack).

• In-game: Ordnance Damage puts enemies into Jinxed state. Killing a Jinxed enemy grants +20% Ordnance Cooldown Rate (up to 10Stack)
• Web (Lootlemon): Whenever C4SH deals Ordnance Damage to an enemy, that enemy becomes Jinxed. Whenever C4SH kills a Jinxed enemy, he gains +20% Ordnance Cooldown Rate for 12 seconds. This effect stacks up to 10 times. Always comes with the Stat: +29% Ordnance Cooldown Rate
• Exclusive status +29% Ordnance Cooldown Rate (Ordnance CD speed)
• ※Skill bonuses (+N) and associated stats vary per individual (＝selection point).
• Weakness: Benefits assume Ordnance skill = builds not centered on grenade/Ordnance find it less useful

Drop Farming

Build Synergy

• Core of Ordnance spin build: Jinxed kills accelerate Ordnance CD up to 10Stack = a C4SH build that continuously fires grenades/Ordnance gains an extra tier
• Exclusive +29% Ordnance Cooldown Rate: Since CD speed is boosted from the start, it directly ties to Ordnance enhancement skills/equipment
• Maximum efficiency in mob-dense areas: The Jinxed→kill loop shines in large-scale fights where it cycles easily
• ※The skill that receives the bonus varies per individual (＝selection point).

Summary

• C4SH (Rogue) exclusive. Ordnance Jinxed → kill → Ordnance CD acceleration grenade spin specialization
• Exclusive +29% Ordnance Cooldown Rate raises CD from the start
• Benefits assume Ordnance skill = for Ordnance-centric builds
• Obtained from Primal Guardian Origo (Arch of Origo)
