A Universal Time Halloween update has brought Hollow boss that you can beat to get candy, Grimharrow title, and more. He looks like a strong and spooky skeleton that deal heavy damage.
The boss also spawns minions while attacking players and thus, is quite difficult to beat solo. Thus, you can join other players and raid the Hollow boss and here is where you can find him and drops that you get.
AUT: Where To Find Hollow Boss Location & Drops List
Hollow Boss spawns in the new area added with Halloween update i.e. Cathedral every hour as per the world time. In order to reach Cathedral, you need to go to the main park in the City Center, where you find Crafting, Guide, and other NPCs.
Among these NPCs, you will see one with the name Bawx (Bawxstar) with an orange aura around him standing on the left side of Guide NPC. Talk to him and he will teleport you to Cathedral.
Enter the Cathedral and Hollow will spawn inside it in the middle. You might have to wait a bit for him to spawn or if you are doing other quests as well in the meantime, you will get the notification on top of the screen saying "Hollow Has Spawned."
Hollow offers multiple drops on getting killed, each having different chances:
- Purple Candy: 10%
- Green Candy: 90%
- Cursed Apple: 50%
Keep in mind that minions don't drop anything and apart from this, if you deal 10% damage to the boss, you will earn the "Grimharrow” title after he dies.
