Boss Ghost
The Boss Ghost is an NPC that was added as part of the B.O.O. Update. To summon the boss, the player must complete the Dark Spirit Board's riddles. To kill the boss, players must equip a Neutron Pack, Neutron Gun, and Spectral Goggles & trap inside of several Containment Field Power Nodes (these need to be powered using Ghost-In-A-Jars). The boss has around 60,000 HP and is only present in worlds for 20 minutes.
Guide
To successfully defeat the boss ghost, the player must bring plenty of Ghost-In-A-Jars to put into the Containment Field Power Nodes. Before summoning the boss, place four nodes into a square formation around the Dark Spirit Board (the farther away each node is from each other the better). This will ensure that the boss gets trapped inside. It is recommended to place a Checkpoint somewhere around the nodes, as players often cross their beams. To activate the nodes, simply click them with a jar selected. Once the nodes are placed and active, gather up several friends and complete the spirit board's riddle. Once the boss is spawned, continue attacking it until it's defeated.
