• New animations: New recall animation..
• New sounds: New sounds for her abilities, auto-attack and recall..

Skin bio & introduction: – Stranded as a child in the Poro King’s enchanted Winterlands, Sejuani was taken in by the poros and raised as their own. She is now one of their greatest champions, riding a slobbery, snack-obsessed war poro against any who would threaten her adoptive home.

How to get this skin? – The skin is not available for purchase and has been placed in the Legacy Vault (they can still be mystery gifted, and only appear in a champion’s information tab if owned). The vault is usually opened for limited runs and this skin can then be purchased in the Riot Store. In my experience it can be rather long between each opening of the Legacy Vault, hang tight!

Worth buying? – Poro Rider Sejuani is a Legacy vault skin — rarely available and not in the regular store. It includes custom particles, new animations, new sounds. You can preview any skin for free on the PBE server before buying. Learn how to access the PBE here.
