“As the blood moon rises above the Black Desert world, mysterious interdimensional portals allow Isabella the Black Witch to haunt the lands. This multi-staged world boss lurks near Costa Farm and players who are skillful enough to beat her are in for fantastic rewards. The Isabella encounter will be available from October 18 up until November 1 and can be accessed by speaking to the White Witch, Gueldia, who has followed Isabella through the portal and resides at Alejandro Farm.”
There’s more, of course! Beginning tomorrow, Kakao will unroll two weeks of daily events. “After successfully completing various challenges, adventurers can earn Halloween-themed rewards such as coins, candy baskets, and cookies,” explains the studio. “The candy baskets and cookies can be combined into Halloween gift boxes and coins can be exchanged at the White Witch NPC Gueldia for Cron Stone, Sharp Black Crystal Shard, Advice of Valks, or a Fine Accessory Box.”
