Palworld Invader Passive Skill
Xenolord always hatches with Invader 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 Invader
Every Pal below hatches with Invader attached, whether you catch it or breed it. The number on each card is how many parent pairs produce that Pal.
Xenolord1 pairHow to breed Invader into a line
Start from a carrier. Xenolord is the one most pairs lead to — 1 parent pair produces it — so it is usually the cheapest way to get Invader 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.
