Skin changes – Jax as conqueror. Specific in-game changes:

• Model: New model, textures and animations!.
• New particles: All new skill particles and animations!.
• New animations: New recall animation!.
• New sounds: New SFX! – New VO processing!.

Skin introduction: – The Conqueror skin line is the mirror to the Championship skin that comes out before Worlds; it’s a new skin that hypes the upcoming Mid-Season Invitational.

How to get this skin? – The skin is not available for purchase and has been placed in the Legacy Vault (It can still be obtained on Hextech  Crafting). 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? – Conqueror Jax 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.
