Red Text
Short for 'Jellifer'.
Throw it and it bounces, multiplies, and chain-explodes. Splashzone (the same boss as Lead Balloon) drops this legendary grenade, upon impact it creates two copies of itself → each bounces around and explodes everywhere, a shot that is extremely strong against hordes. Its straight, simple trajectory makes it appealing for beginners.
Regarding notation The unique ability “Self-Replication” and Japanese red text “Short for Jellifer.” have been confirmed in-game. Details of the effect text and augment names come from English guides, so some are (unverified).
Red Text Trivia
“Short for ‘Jellifer’.” is a name joke: it pretends that “Jelly” is short for “Jellifer,” an invented name twisted out of something like Jennifer. The Borderlands Wiki lists no source material for it, so it looks like pure wordplay rather than a reference.
What kind of grenade? (Beginner’s perspective)
- Throw it and fly straight in a parabolic arc - an honest trajectory (easy to aim)
- On first impact (or after 6 seconds) 100% elemental splash explosion
- Additionally at the impact point creates two copies of itself → each copy bounces up to 4 times, exploding for 50% each time
- Result: with one throw explosions are scattered everywhere - excels at bulk clearing of densely grouped foes
Unique Effect (Mechanics)
Self-Replication: After throwing, on first impact or after 6 seconds a 100% elemental splashexplosion. At first impact it creates copies (2), and each copy can bounce up to 4 times, causing a 50% elemental splashexplosion each time.
- One throw provides “1 main projectile + 2 copies × up to 4 bounces” multi-stage explosions → high area-control power
- Elemental rolls can also grant status effects (Cryo provides powerful freeze)
- Synergizes with elemental builds, letting you disperse status effects across many foes simultaneously
Top Picks (Status Augments)
Jelly receives one of nine status augments (each ~11.1%). Targets (analysis):
| Augment | Effect | Note |
|---|---|---|
| Nuke | +31% Damage / +62% Range / +25% Cooldown | Focus on damage and range. Further strengthens area control. |
| Expansive | +41% Range | When you want to increase the engulf area. |
| Explosive | +21% Damage | Straightforward damage boost. |
| Hazardous | +17% Status Chance / +33% Status Damage | Great synergy with elemental builds. |
| Overflow | +1 Charge | Increases number of charges (inventory). |
About these augment names Nuke, Hazardous and Expansive were verified in-game, but on a Japanese client — the numbers are first-hand, the English labels are matched from English guides. Treat the names (not the values) as unconfirmed.
