How to Breed Necromus
in Palworld 1.0
Necromus only hatches from two Necromus parents. Catch or obtain one first; breeding is for passives and mutation odds, not for getting your first one.
Unique combos
Cross-species pairs that produce Necromus outside the normal element rules. Some require a specific gender on one or both parents.
The Cake requirement
Every breeding attempt at a Breeding Farm consumes one Cake from the chest attached to it. Keep a stack on hand before you start a route this long. Running dry partway through a chain is the most common reason a breeding project stalls.
Passive inheritance
Passives can pass from a parent to its offspring during breeding, and which ones make it through is partly random. The odds are well understood from community reverse engineering of Palworld 1.0: a child directly inherits 1 to 4 passives from the parents pool (40/30/20/10 percent for exactly 1/2/3/4), then 0 to 3 random passives can be added on top (40/30/20/10 percent for 0/1/2/3). The Breeding Calculator now turns those constants into per-egg odds and an expected egg count for the exact passives you are hunting.
Frequently asked questions
Can you catch Necromus in the wild in Palworld 1.0?
No. Necromus never spawns in the wild, so breeding is the only way to add it to your Paldeck.
What do you breed to get Necromus?
Only a pair of Necromus produce a Necromus egg. No cross-species combo results in it.
