How to Find the Corruption Portal and Summon Annihilation

Locating the Corruption Portal

The Annihilation boss fight takes place at a massive dark stone and purple arena called the Corruption Portal, which generates naturally in the Overworld. You can explore your world to find the structure on foot, or bypass the search entirely if you have operator permissions.

To teleport straight to the arena, open your chat and run:

/function annihilation:admin/_/tp_to_portal

Starting the Boss Encounter

In a standard survival playthrough, you start the multi-phase encounter at the portal structure:

1. Prepare the summoning tribute item required for your game version.

2. Walk up to the center of the Corruption Portal.

3. Right-click the center of the portal while holding the summoning tribute item.

4. Step back and prepare to dodge the boss's custom attack patterns.

Spawning the Boss with Commands

If you are testing the fight in Creative mode or building a custom arena, you can skip the summoning tribute and spawn the boss directly via commands.

To spawn Annihilation inside the Corruption Portal structure from anywhere:

/function annihilation:admin/_/summon_at_portal

To spawn the boss immediately at your current character coordinates:

/function annihilation:admin/_/summon
