1. There is an announcement in the game for the rare boss at the top of the main screen counting down to when the rare boss will respawn. When the timer ticks down to zero, you'll see another announcement forwhere the rare boss will spawn.
2. There are different minimum requirements of level in different places(bosses) for Banishment. We suggest you challenge these bosses one by one when you reach the specified level.
3. Under normal conditions, the player who gets the first hit to the rare boss will "claim" that boss, and only they and their team will get the rewards for killing the boss. Alternatively, you can kill that person to claim the boss as yours. Onlythe person who claims it, and people in their "Team" will get therewards.
4. You can get Sun Wukong shards from Time-limited Hero when he is available. For further Time-limited Hero news, please pay attention to the news and announcement in official website.
