[Event] Black Spirit's Illusion - Oblivion

The Black Spirit says it feels a power similar to what it felt last time. Even though it is significantly weaker, it's still noteworthy and the Black Spirit wants to absorb it all. Obtain [Event] Shard of Illusion - Oblivion and show it to the Black Spirit.

※ You can obtain [Event] Shard of Illusion - Oblivion by completing The 7th Illusion - Oblivion at Altar of Blood during the event period.
