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.
Kill directly restores health, a survivability set that doesn’t rely on repair kits.
Full (3 pieces) Effect
Heal 10% of max HP on kill
- The more low-level enemies, the more healing cycles, allowing continuous pushes
- Since it references max HP, it multiplies with Baker’s max HP +25%
- In single boss fights, kills don’t occur, making it almost ineffective
It is the opposite philosophy of Risky Boots which maintains low HP for firepower. Stacking them together cancels each other out.
How many to activate?
Firmware’s effect changes in stages depending on how many of the same set you have equipped.
| Tier | Required | Effect of Lifeblood |
|---|---|---|
| Minor | 1 piece | (unverified) |
| Major | 2 pieces | (unverified) |
| Full | 3 pieces | Heal 10% of max HP on kill |
The exact values for Minor / Major are unverified. Minor (1 piece) and Major (2 pieces) have set-specific constant increases, and there is no reliable public source listing 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 / Ordnance / 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 Lifeblood on the Full side, choose a set for the remaining two slots that provides constant increases you actually use in your build. If the two-piece side’s numbers are dead, the effective cap works only for three slots.
Acquisition & Swapping
- It appears randomly on gear level 25 or higher (not on weapons).
- Stats within the same set are considered identical across instances, so selective farming of perfect pieces is unnecessary (observed on hardware; comprehensive verification of all 21 sets is ongoing).
- Gear can be transferred between items using the Transfer Machine. Transfer is only possible between the same gear type, regardless of item level or rarity. The donor gear is destroyed, and the transfer is locked after one use.
