Get ready to raid Ghost of Tsushima on October 30th – Engadget

Using max level gear earned from the Challenges, Ghosts will be able to undertake raids starting October 30th with the three-chapter Tale of Iyo. It will require full teams of players but beware there is no matchmaking here, you’ve got to get your crew together ahead of time.

And their gear had better be right. In fact, the announcement warns specifically “you’ll want to have your gear at KI level 100 as an absolute minimum before you attempt to take on this challenge.” So you’d better get back to grinding through the game at higher difficulties.
