Over the course of Terraria's development, there have been a great deal of infamously difficult bosses, from Skeletron Prime to Empress of Light, these bosses are infamous for their above average difficulty. Yet, easily the most powerful boss of the all: Grubby. This guide will demonstrate how to access and kill this secret boss.

The first step of our Journey involves us installing the Calamity Mod.
Normal Terraria weapons crumple like paper before grubby, but the strongest Calamity weapons may be able to scratch him through his unobtanium carapace.



For this run, we will be using the Mursama, a endgame true melee weapon that heavily references Metal Gear Rising: Revengance.

Here is an excellent video displaying how to make the best possible build with this weapon (skip to 0:40 for the setup):


Play and beat Calamity normally so that you can make this loadout.

Congrats! We are now ready to make the arena.

The next step in killing grubby is just to build a simple arena. Just copy the image below for the best possible arena!

Grubby is a boss in the Terraria Calamity Mod, which is a fan-made modification for the popular game Terraria. To summon Grubby, you need to meet certain conditions in the game:

You must have defeated all of the mechanical bosses in the game (The Twins, The Destroyer, Skeletron Prime, etc.).

You must have at least 200 maximum health and 200 maximum mana.

You must have the Dimensional Shard, which can be obtained by defeating the Ancient Cultist.

You must be playing in Expert mode.

Once you have met these conditions, you can summon Grubby by using the Dimensional Shard at a designated summoning point in the game. Keep in mind that Grubby is a very challenging boss and you should come prepared with good weapons and armor before attempting to defeat it.
