League of Legends Hallowe'en update adds The Shadow Isles

League of Legends is getting into the holiday spirit with a new environment, some themed skins, and a brand new champion, Elise the Spider Queen.

The upcoming League of Legends patch adds in something called The Shadow Isles; it's not clear whether this is a whole new map or a holiday skin for an existing location.

Riot is urging summoners to swear their allegiance to the new location, by means of a handful of new skins for existing characters - Headless Hecarim, Haunted Maokai and Underworld Twisted Fate. Players are advised to keep an eye out for new Harrowing-themed character skins, something called "ward skins" and summoner icons.

Perhaps most importantly, the update brings an all new champion. Elise the Spider Queen was first conceived three years ago but Riot notes her unique abilities made her "challenging" to realise. Elise is able to switch between spider and human forms, and has a swathe of skills in either body - get all the details here.

The patch is expected on October 31.
