Can I still learn Thunder Rail on a new Grizzbolt?
No. Grizzbolt breeds only from Grizzbolt parents in v1.0.3 in Palworld 1.0. Only a Grizzbolt that already carries Thunder Rail from an earlier version satisfies this build.
Can Grizzbolt Learn Thunder Rail in Palworld 1.0?
Checked against Palworld v1.0.3 · verified 2026-08-23 · Data status
Legacy Pal required
Not from scratch. In Palworld v1.0.3, Grizzbolt cannot newly learn Thunder Rail under verified methods (Grizzbolt breeds only from Grizzbolt parents in v1.0.3), but it could in v0.7.0. A legitimate pre-v1.0.3 Grizzbolt that already carries it can pass it on, so this build requires a legacy Pal. The facts behind this answer are graded B and come from 2 registered sources.

Why
- No obtainable Skill Fruit for Thunder Rail is verified in v1.0.3.
- In v1.0.3, Grizzbolt can only be bred from two Grizzbolt parents, so no other species can bring Thunder Rail into its lineage.
- Thunder Rail was obtainable on Grizzbolt in an older version through a verified path.
- A Grizzbolt that already carries Thunder Rail can pass it to its offspring in v1.0.3, so the build survives only through an existing legacy lineage.

Where it stops
- Pals that obtain Thunder Rail directly exist in v1.0.3 (Azurmane, Puffolt, Slowatt and Snock).
- Thunder Rail can be inherited through breeding.
- Grizzbolt has only one breeding recipe in v1.0.3: Grizzbolt + Grizzbolt, so no other species can bring it in.
- Before 1.0.3, Grizzbolt could be bred from other species, which is how older Grizzbolt got Thunder Rail.
- In v1.0.3, Grizzbolt can only be bred from two Grizzbolt parents, so no other species can bring Thunder Rail into its lineage.
What you can do now
- Keep or obtain a Grizzbolt from Palworld v0.7.0 or earlier that already carries Thunder Rail.
- That carrier can pass Thunder Rail on: Grizzbolt can be bred from two Grizzbolt parents.
