Spooky Mobs

Spooky Mobs are mobs that are only available during the Spooky Festival at night. There are 6 Spooky Mobs that currently exist. The Mega Bat could be considered a Spooky Mob, but it is not officially confirmed. They all only take 1 damage from weapons that do not have any special effects against them.

The Bat Pet can increase the damage dealt to them by up to 50% when it is at level 100 and the Ghoul Buster's special ability increases damage dealt to them by 100%, along with Blast o' Lanterns, which deal 2 damage to them.

The best Reforge for fighting Spooky Mobs is Fast as Bonus Attack Speed is the only way to increase DPS against them.

Aside from Trick or Treat Chests, Phantom Spirits and Wraiths are the only source of Ectoplasm.

Spooky Mobs only spawn in areas where normal mobs usually spawn, such as the Graveyard, Deep Caverns, Spider's Den, and The End. However, they can also spawn in the Wilderness.

Melee Spooky Creatures, such as Scary Jerry, Phantom Spirit and Wraith ignore invincibility frames when striking players, causing rapid health loss if not taken down fast enough.
