Palworld Siren of the Void Passive Skill
Bellanoir Libero always hatches with Siren of the Void in Palworld 1.0. Breeding from one of them is the reliable way to get the skill onto a line, because it is on the parent already instead of being rolled at random.
The Pal that always has Siren of the Void
Every Pal below hatches with Siren of the Void attached, whether you catch it or breed it. The number on each card is how many parent pairs produce that Pal.
Bellanoir Libero1 pairHow to breed Siren of the Void into a line
Start from a carrier. Bellanoir Libero is the one most pairs lead to — 1 parent pair produces it — so it is usually the cheapest way to get Siren of the Void into your ranch. From there, pair the carrier with the Pal you are building and keep the eggs that inherit the skill.
Both parents contribute to the pool, so two carriers are better than one when you are stacking several passives at once. The Passives tab in the calculator filters the whole Paldeck down to the Pals that guarantee the skills you pick.
What this list covers. These are the passives tied to a species — a Pal of this kind always hatches with the skill. Palworld also rolls other passives at random on any egg; those are not attached to a Pal and so cannot be looked up here.
