Redmane Castle Walkthrough: How to Find It
You can see Redmane Castle opposite the bridge from the Site of Grace called Impassable Greatbridge. Unfortunately, the entrance is locked, so you'll need to take the right pathway around, using the fallen wall from the nearby tower and Torrent to make your way. Climb the ladders inside this tower for a Smithing Stone . Then continue around the exterior of the castle, past the Bats, into a courtyard area. Defeat the Teardrop Scarab for Ash of War: Flaming Strike, then climb the massive ladder, drop down, and enter the stable room. Kill the commoners and loot the corpses for Armorer's Cookbook  and Smithing Stone . Don't forget to unlock the door for a faster route back inside the castle.
Redmane Castle Walkthrough: Attending the Radahn Festival
There's very little you can do in the room opposite, so instead climb the ladder to your right and then drop down into the courtyard. Up the stairs is a Golden Rune , while two Lion Guardians patrol the entrance. You can use Summon Spirits to help with these, and killing them will reward you with Somber Smithing Stone , Beast Blood, and Old Fang. You can also loot a Smithing Stone  on the pile of bodies in the area.
Head up the steps, past the teleporter, to a Site of Grace called Chamber Outside the Plaza. Head back outside to the gallows area and climb onto the roof for another Smithing Stone , then head to the Radahn Festival. You can speak with various characters, here, including Iron Fist Alexander and Blaidd. You'll get a Gesture from the lady called Polite Bow. Head up the stairs and speak to the NPC directly on your left for a cut-scene and another Gesture. Then on the right loot a Somber Smithing Stone  and head inside the chapel for a Smithing Stone . Take the lift to a teleporter and enter it for Starscourge Radahn. You can find out How to Beat Starscourge Radahn through the link.
Redmane Castle Walkthrough: Resetting the Castle
Redmane Castle can be different depending on your progress through quests. If you haven't progressed Ranni the Witch's quest or taken the Grand Lift of Dectus then you'll have to face off against a Lion Misbegotten Warrior and Crucible Knight. However, more doors will be open allowing you to collect more loot. If you have already progressed the quests then speak to Blaidd directly after Starscourge Radahn, then chat with the NPC in the chapel you went in shortly before fighting Starscourge Radahn. He'll tell you his job is done and when you return to Redmane Castle, it'll be reset, allowing you to enter areas you couldn't previously.
