Resurrection Orb

"Make a sacrifice...do a resurrection...what will you get?"

The Resurrection Orb is the very last step to summoning the last Hardmode boss, The Doom. It is a special item, as it requires placement of certain liquids in certain places, in a certain biome.

It serves no purpose but to summon The Doom. Right clicking it will not do anything.

One needs to pour honey in a 3 wide hole. It doesn't matter how deep it is. There also needs to be a 3 wide hole of lava after the honey, and also a 3 wide hole of water after the lava. This all has to be done in the Underground Corruption/Underground Crimson.

Now, similarly to the Guide Voodoo Doll, the player has to throw the Resurrection Orb in lava. This will immediately summon The Doom and will initiate the fight.

The Doom can be fought anywhere, not just the Underground Corruption/Crimson. One can also fight it on the surface by teleporting there, as The Doom will not despawn by simple means like teleporting away.

This will also kill all NPCs in the world. They will also not respawn until the day after the boss is defeated. Thus, the player cannot cheese the battle with the Nurse.
