The Harrowing returns to League of Legends

League of Legends is celebrating Halloween in style with the Harrowing, a suitably spooky seasonal event.

The Harrowing brings with it a new play mode, Hexakill. Hexakill is a 6v6 mode on Twisted Treeline, which is usually reserved for 3v3 modes, so expect in-your-face action as players navigate the den of a giant spider.

Otherwise, there are a number of skins on offer. LeBlanc and Wukong have all new skins, while past harrowing skins for other charavters make a return.

Riot is offering discounts on a range of Harrowing skins, allowing you to collect 'em all in bundles or hang out for flash sales to grab your favourites.

For more information, check out the cinematic below and visit the event page.

Thanks, Joystiq.
