Every night at 11:00 PM (EST) gate to Sky Castle will open, all users have to get teamed up to take down the Sky Boss in the castle. When the Sky Boss ends, as a compensation, gift item is given to all users who are in the Sky Castle or around the Sky Castle.
Sky Castle is now timer based, only 1 hour per day. Sky Boss will randomly spawn.
What's around the Sky Castle?
Sky bosses like Death Knight, Baphomet, Iris, Grim Reaper, Knight Vald, Mambo Rabbit, and more.
These monsters drop Zero custom items, and rare weapons, armors, accessories, and more
TIPS
You can not summon in the Sky, so you have to summon before you teleport through the gate
These monsters are strong but low HP compare to real boss monsters
