Skin changes – ChoGath as a dark blue Terror of the Void.. Specific in-game changes:

• Model: New textures for ChoGath..

Skin bio & introduction: – Hailing from the Void, Cho’Gath is a terror of death that was borne in a dimension between dimensions . Because of the violent nature of the dark rift, not much is known of the Voidborn. Cho’Gath is a creature of pure darkness, a being that feeds on anything and everything in its path, devouring and learning until there is no more.

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? – Nightmare Cho’Gath is a Legacy vault skin — rarely available and not in the regular store. You can preview any skin for free on the PBE server before buying. Learn how to access the PBE here.
