Skin changes – Rumble as a yordle buccaneer.. Specific in-game changes:

• Model: Major model changes for Rumble and Tristy..
• New particles: New cannonball particles for The Equalizer..

Skin bio & introduction: – When the burdens of invention weigh too heavy on a young yordle’s shoulders, there’s no better choice than to take to the seas! Nothing like plunderin’ and maraudin’ to lend Rumble a new lease on life as he terrorizes the coasts.

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? – Bilgerat Rumble is a Legacy vault skin — rarely available and not in the regular store. It includes custom particles. You can preview any skin for free on the PBE server before buying. Learn how to access the PBE here.
