Finding seeds in Muck is a challenge. Using some mods however we can help aid us in our efforts of searching through the vast universe of seeds.

Please consult this guide What Mucks Rarest Seed Looks Like?!?! regarding the rarest seed in Muck to find more information on the general process I use.

Hello everyone, after someone commented on one of my other guides regarding a famous NightBlade seed, I decided to attempt to beat it and have been working on a new muck mod. I have made another world jump mod that is looking for a seed that contains a Night Blade (sword) in a chest near spawn. The seed he posted has one at 330 blocks away. The sword has a 0.1% chance to spawn in cave chests; Caves are already very rare spawns themselves (Check out my Spawn In Caves Seeds?! guide).

Using some mods, I created a way to automatically generate a world, check if there exists a chest containing a nightblade, check if it's within <= 300 blocks from spawn (Record seed if true), and repeat. Below is the closest Night Blade Chest from searching through 100,000 randomly generated seeds.

Please leave me a seed request in the comments or friend me to explain details!
