What It Does

This single-use consumable applies Immortality (Life Steal 5%, HP Regeneration +100%, and Attack +15% — the best sustain passive in the game) at the Pal Surgery Table . The surgery itself is free; the implant is consumed.

Vampiric offers the same life steal from the cheaper any-grade implant pool, but Immortality adds double-speed regeneration and an attack bonus on top without forcing a nocturnal schedule. On raid and expedition Pals that have to survive without a healer, it's close to mandatory.

Where to Get It

Immortality is one of the five mutation passives, so its implant sits in the recycler's top tier: it only drops when recycling Glistening Ancient Relics at the Ancient Relic Recycler — a 20% roll in the Glistening-exclusive slot. The passive never rolls on wild Pals; the only other way to get it is hatching it from a mutated egg and breeding it onward. See the Ancient Relics guide for the reward tables and the implants guide for how surgery works.
