Skin changes – Kog’Maw sports a brown insect-like look.. Specific in-game changes:

• Model: New textures for Kog’Maw..

Skin bio & introduction: – Long considered a pest by frontier settlers, Kog’Maw critters have been growing in number as more beasts are pushed to the brink of extinction. And they are very, very hungry.

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? – Sonoran Kog’Maw 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.
