| Drop source | Randomly applied to 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.
Defeating a Badas class grants a damage buff that lasts for 1 minute. Its duration is exceptional even among all sets.
Full (3 pieces) Effect
Defeating Badas grants +20% damage (60 seconds)
- 60 seconds is orders of magnitude longer compared to the 5–15 seconds of other sets
- If the area continuously spawns Badas, it can effectively be treated as a constant buff
- In single fights that go straight to the boss, there is no activation opportunity, reducing its value
Similarly, the kill‑based Airstrike earns its effect from the number of grunts, whereas this type lasts long by defeating a single higher‑rank enemy.
How many are needed to activate?
Firmware’s effect changes in stages based on how many of the same set are equipped.
| Tier | Required number | Effect of God Killer |
|---|---|---|
| Minor | 1 piece | (unverified) |
| Major | 2 pieces | (unverified) |
| Full | 3 pieces | Defeating Badas grants +20% damage (60 seconds) |
The exact values for Minor / Major are unverified. Minor (1 piece) and Major (2 pieces) provide a set‑specific constant increase, and there is no reliable public source that lists the exact values 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 applies to the five slots other than weapons — Shield / Ordance / Class MOD / Enhancement / Repair Kit. The maximum configuration is 3 pieces of one set (Full) + 2 pieces of another set (Major) in a “3+2” arrangement, and two Fulls cannot be equipped simultaneously.
If you place God Killer on the Full side, choose a set for the remaining two slots that provides a constant increase actually used in your build. If the values on the 2‑piece side are dead, it effectively only works for three slots.
Acquisition & Swapping
- Gear of Lv25 or higher can randomly have it (weapons cannot).
- Since the stats within the same set appear to have no individual variation, selecting a perfect piece is unnecessary (observed on hardware; comprehensive verification of all 21 sets is ongoing).
- Transfer machines allow moving it between gears. 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.
