Silksong's Permadeath Steel Soul mode unlocked by entering up, down, up, down, left, right, left, right at the extras menu
It's not just a hardcore challenge where if you die, you have to start all over with a new save file
It's also a way to experience a quest and boss battle that doesn't exist outside the challenge mode
One such quest is the Avassal Lost quest, and here's how to get it
Quick note and fair warning that for the purpose of this video, we're actually using an infinite health mod
So if it seems like we're cheating, we are. It's going to take us a lot longer to get back here in Steel Soul Mode, so we skipped ahead to show you what's in store, even if you don't plan to take on this insane challenge
With Steel Soul Mode enabled using the code we mentioned right at the beginning, play through the game as normal until you're able to reach the blasted steps
Make your way to where Chakra is right here on the map, then platform and fight your way upwards until you're positioned at this location, where you can jump to your right and reach a platform with a chest of rosaries and a falling rock above
Break this wall and head inside. In the regular mode this will just be a spot where you can find a Silkeater But in Steel Soul mode there will be another exit that leads to an NPC named Seer Z Hit her to begin the quest and then chat with her until her dialogue is exhausted
You'll need to visit a series of resting spots that are marked on your map. They are random spawns, so you'll need to track down each of them on your own
Once you find all three resting places, you'll need to head to Bonegrave, which is located to the left of Bone Bottom, just past the Chapel of the Wanderer
If you haven't unlocked this area yet, you could use the simple key and head through the Wormways
but since you already have the Klingrip, you can actually just get there just by hopping up this
wall in Bone Bottom and continuing all the way to the left. Work your way down to the bottom of
the tunnels, or you'll spot a bug doing a summoning ritual. Get ready for a boss fight. The Summoned
Savior is a black mass with several shells protruding from it that uses dash attacks
throws out blobs that turn into spinning blades, and can summon blades around itself
Once you defeat it, chat with Summoner Sula, then head back to Seer Z for your reward
a Growstone, which is a consumable item that grants Shell Shards and reforms over time
And that's it! Thanks for watching, and for more Hollow Knight Silksong tips and tricks, keep it here on IGN
