Borderlands 4 Faulty Detonator Review — Legendary Ordnance

Red Text
He improvised that, you know…

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.

After landing and exploding, it scatters five homing drones to chase and follow up, a “two‑stage” grenade. Made by Tediore, in addition to the main explosion, “Shoot Me” drones chase enemies and self‑destruct. One throw delivers multi‑stage damage from the main body plus five drones.

🧩 Source of the red text “He improvised that, you know…” is, primary information indicating a specific movie/character line is unverified → (unverified). Combined with the name “Faulty Detonator” (defective detonator), it reads as a wordplay meaning “failed to detonate and improvised on the spot”, i.e., the explosion didn’t go as planned and is recovered improvisationally with homing drones. The “Shoot Me” written on the drones is also self‑deprecating humor typical of Tediore. External source will be added once identified.

What kind of grenade? (Beginner’s perspective)

• Throw in a large arc, and remain where it lands
• After 6 seconds, or remote detonation, it explodes (100% [element] splash)
• At the moment of explosion, it spawns five homing “Shoot Me” drones
• The drones chase enemies and self‑destruct on impact (each 50% [element] splash)
• If the drones are shot, they explode early (but damage does not increase)
• The main body plus five drones deliver multi‑stage damage, effective against both groups and single targets

Unique effects (mechanics)

Throw in a large arc, remain at the landing point. After 6 seconds / remote detonation it explodes (100% [element] splash) and spawns five homing “Shoot Me” drones. The drones explode on impact (each 50% [element] splash). If shot, they explode early without increasing damage.

• In‑game: Generates a combo orb on explosion
• Web (Lootlemon): Thrown in a heavily arcing trajectory, it rests where it lands. After 6s or on remote detonation it explodes for 100% [Element] Splash. It then spawns 5 homing “Shoot Me” Drones that explode on impact (50% [Element] Splash each). If the Drones are shot, they explode early without increasing their Damage.

Difference from in‑game text (unverified) The in‑game card says “Generates a combo orb on explosion”, whereas the web guide (Lootlemon) states “spawns five homing drones”. It needs to be confirmed whether “combo orb” and “Shoot Me drones” are different wording for the same behavior or separate elements (verify in‑game to confirm).

• Thanks to the homing drones, they will chase enemies even if you just throw it
• Weakness: The main body stays where it lands, making it hard to hit moving single targets directly with the main body (relying on drones)

Drop farming

Build compatibility

Summary

• Main explosion + five homing drones multi‑stage grenade
• Because drones chase enemies, throw‑and‑forget follow‑up works
• The main body lands and stays = hard to directly hit moving single targets (relying on drones)
• The notation difference between “combo orb / Shoot Me drones” is (unverified)
• The external source for the name and red text is (unverified)
• Obtained from Skull Orchid (Embossed Fault)
