Borderlands 4 Airstrike Review — ファームウェア
| Type | ファームウェア |
|---|---|
| Drop source | Randomly granted on gear (Shield / Ordnance / Class MOD / Enhancement / Repair Kit) of level 25 or higher |
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.
A set that drops additional missiles each time an enemy is defeated, creating a grunt processing chain.
Full (3 pieces) Effect
When you kill, drop a missile strike on nearby enemies
- Since it is kill‑based, it works snowball‑style in areas where many enemies spawn
- Conversely, in a solo boss fight there is almost no chance to trigger it
- It meshes with builds that extend splash / area damage
Even with the same kill‑based trigger, God Killer is a buff type limited to Badass and lasts 60 seconds. If you want to earn by numbers, use this one; if you want to keep a higher‑tier enemy alive longer, use the other.
How many to activate?
Firmware changes its effect progressively depending on how many of the same set you have equipped.
| Tier | Required number | Effect of Airstrike |
|---|---|---|
| Minor | 1 piece | (unverified) |
| Major | 2 pieces | (unverified) |
| Full | 3 pieces | When you kill, drop a missile strike on nearby enemies |
The actual numeric values for Minor / Major are unverified. Minor (1 piece) and Major (2 pieces) increase constants uniquely per set, and there is no reliable public source that lists the actual numbers for all 21 sets. This page will be updated as soon as they can be confirmed on actual hardware.
How to arrange the 5 slots (3+2)
Firmware attaches to the five slots other than weapons — Shield / Audance / Class MOD / Enhancement / Repair Kit. The maximum configuration is one set of 3 pieces (Full) + a separate set of 2 pieces (Major) for a “3+2”, and you cannot stack two Fulls simultaneously.
If you place Airstrike on the Full side, choose a set for the remaining two slots that provides constant increases you actually use in your build. If the numbers on the 2‑piece side are dead, it effectively works for only three slots.
How to obtain & replace
- Gear of Lv25 or higher can randomly have it (weapons cannot).
- Since the stats within the same set are considered identical across individuals, there is no need to farm for a perfect piece (observed on hardware; comprehensive verification of all 21 sets is ongoing).
- Transfer Machine can move it between gear. Only between the same gear type; item level and rarity do not matter. The donor gear is destroyed, and the transfer is locked after one use.
