How dare you!?
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.
Every time a critical hit lands, ammo returns to the magazine, making the “hard-to-run-out” Vladof-made assault rifle. It always spawns with an elemental attribute and full-auto; the longer you fire, the higher the fire rate. The more you can aim for weak points, the less the magazine empties, allowing continuous fire.
🧩 Red Text origin “How dare you!?” is a well-known exasperated phrase in English-speaking regions. The weapon name “Lucian” is said to be derived from BL3 and named after Gearbox employee Jett Sarrett’s child (Lucian/Rowan) (Fandom). Meanwhile, whether “How dare you!?” refers to a specific work/person (e.g., the 2019 Greta Thunberg speech meme) is not confirmed by primary sources, only summarized sources. External source is (unverified).
What kind of assault rifle? (Beginner’s perspective)
- Vladof-made full-auto AR. It exhibits typical Vladof behavior where fire rate increases as you keep shooting
- Always spawns with elemental attribute (Always Elemental)
- Its unique effect returns ammo to the magazine on each critical hit, so continuously landing weak points drastically reduces reload frequency.
- Spawns always with Extra Barrel and Jakobs license accessory (=> stable accuracy and recoil characteristics)
Unique Effect (Mechanics)
Trample - Critical Hit when it occurs, up to 2 shots of ammo are refilled into the gun’s magazine
- In-game (Japanese): Trample - When a Critical Hit occurs, up to 2 shots of ammo are refilled into the gun’s magazine
- In-game (English): Trample — Critical Hits refill up to 2 Ammo to the Gun’s Magazine.
- Web (Lootlemon): Critical Hits refill up to 2 shots to the magazine. However, there is an internal cooldown (it does not generate infinitely)
- Always Elemental • Always equipped with Extra Barrel + Jakobs license accessory
- Weakness: Missing a critical nullifies the benefit = if you cannot continuously land weak points, it becomes just an AR
