Palworld Hard Skin Passive Skill
4 Pals always hatch with Hard Skin 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.
Pals that always have Hard Skin
Every Pal below hatches with Hard Skin attached, whether you catch it or breed it. The number on each card is how many parent pairs produce that Pal.
How to breed Hard Skin into a line
Start from a carrier. Warsect is the one most pairs lead to — 858 parent pairs produce it — so it is usually the cheapest way to get Hard Skin 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.
