Skin changes – Ekko as a Haloween nightmare. Specific in-game changes:

• Model: New model, textures and animations!.
• New particles: All-new particles: Spooky greens and purples, and of course, pumpkins!.
• New animations: New recall animation: What happens when you’re only supposed to take one piece of candy….
• New sounds: All-new sound effects: Ghoulish screams and ominous tones!.

Skin bio & introduction: – Perhaps, in hindsight, looping time to get an infinite number of fun-size chocolate bars wasn’t worth shattering the fabric of reality for…

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? – Trick or Treat Ekko 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.
