Tamriel’s ancient autumn tradition, The Witches Festival, has kicked off for October!

For the rest of the month, demonologists, conjurors, lamias, warlocks, and thaumaturgists will come together to celebrate the season with the players. During the event, players will be able to turn any members of the group into the Undead, get a 100% EXP boost, unlock special event achievements, and increased loot drops, including the Hollowjack motif, exclusive masks and more.

To join in, you need to visit the Crown Store for a free Crown Caller, then blow into it to get The Witchmother’s Bargain quest. Finish that, and you’ll get the Witchmother’s Whistle, which unlocks The Witchmother‘s Cauldron, that polymorphs players and their group into the Undead. It’ll only last two hours, but can be used as many times as they like until the first day of Sun’s Dusk (November 1).

When your polymorph is active, killing bosses will provide the chance to loot Plunder Skulls. Open these for exclusive goodies including masks (equipped in the hat slot), special holiday Provisioning recipes, the Hollowjack crafting motif, and more. Also, in case you forgot, there’s the “Trip of a Lifetime,” giveaway, which will award five lucky Grand Prize Winners an amazing trip to places around the world like Tamriel itself. If you want to enter, just log in and play ESO, then register here to enter.

You’ve only got until December 16, so be quick about it!
