• Model: New model for Katarina and her blades..
• New particles: New projectile for Bouncing Blade and new particles for her abilities..
• New animations: New recall animation..
• New sounds: New sounds for her recall..

Skin bio & introduction: – Donning a mishmash of Snowdown fashions to throw targets off her scent, Katarina uses the holidays as a cover for high profile assassinations. If you hear the sound of jingle bells…run.

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? – Slay Belle Katarina 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.
