| 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.
Increase action skill rotation straightforwardly, the foundation of a skill-centric build.
Full (3 pieces) Effect
Action Skill Cooldown Rate +20% (additional)
- A constant effect with no conditions or duration. No situation where it becomes obsolete.
- If the action skill is the main gun in the build, it’s worth placing on the 3-piece (Full) side.
- It aligns with Action Fist that increases skill damage with melee kills.
The name is displayed in-game in Japanese as “GOOJFC”. The English GOOJFC stands for Get Out Of Jail Free Card (the Monopoly “Get Out of Jail Free Card”), and the Japanese name was confirmed from the inventory card notation “GOOJFC 0/3”.
How many to activate?
Firmware’s effect changes in stages depending on how many of the same set are equipped.
| Tier | Required number | Effect of GOOJFC |
|---|---|---|
| Minor | 1 piece | (unverified) |
| Major | 2 pieces | (unverified) |
| Full | 3 pieces | Action Skill Cooldown Rate +20% (additional) |
The actual values for Minor / Major are unverified. Minor (1 piece) and Major (2 pieces) provide set-specific constant increases, and there is no reliable public source that lists the actual 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 can be attached to the five slots other than weapons — Shield / Ordnance / Class MOD / Enhancement / Repair Kit. The maximum configuration is 1 set of 3 pieces (Full) + a separate set of 2 pieces (Major) “3+2”, and you cannot stack two Fulls simultaneously.
If you place GOOJFC on the Full side, choose a set for the remaining 2 slots that provides constant increases actually used in your build. If the values on the 2-piece side are dead, the effective maximum works only for 3 slots.
How to collect / replace
- 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 individual is unnecessary (observed on hardware. Comprehensive verification of all 21 sets is ongoing).
- Transfer machine allows moving 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.
