Undead Valley:

A complete walkthrough for Undead Valley in Dark Souls II: Scholar of the First Sin, detailing enemy encounters, item locations, and strategies for the Skeleton Lords boss fight.

Return to the big iron bridge you lowered earlier. After crossing it, you'll find a Bonfire locked away in a room. You don't have the key for it yet. Go inside the cave to the right. You'll be fighting skeletons that are being revived by a necromancer. Loot the first corpse to get a Magic Mace and Titanite Shard. Head inside and find the necromancer to prevent the skeletons from being revived again.

You'll soon stumble upon a gate you won't be able to open from that side. Go outside the way you came and cross the bridge by killing the rogue. Be cautious not to fall off this narrow road. There should be an uphill path to the left. Follow it and you'll find a corpse in the middle. Kill the rogues before attempting to loot it. Loot the ten Poison throwing knives from the corpse then carefully peek over the edge to find a small ledge you can drop on with a lootable corpse. Get three Poison Moss from it then drop to the main path below.

You'll soon come across a room with a corpse inside to your left. Be warned that rogues guard it. You'll loot the Undead Lockaway Key from it which is required to unlock the third Bonfire which is located before crossing the bridge leading to this narrow path. Inside you'll meet Creighton. Talk to him and learn his gesture.

Continue following the narrow path. Be warned that a dark spirit invader will soon come after you. It's attacks are painful, you can try pushing it off the road or take it straight on. You should find more space before taking it on. Once you've reached the ruins, take the path by the waterfall and you'll find a misty door. Don't enter it yet; inside, follow the other path that leads to a cave filled with skeletons.

The necromancer is located on a platform which you need to jump on. Kill the skeletons first, and jump on the necromancer's platform while he ressurects them. Take the path to the right and loot the corpse on the ledge you see. You'll get a Combustion spell and three Titanite from it. Continue forth and take out one last skeleton. Loot the corpse behind it to get three Flame Butterflies. Pull the nearby lever to create a shortcut near the third Bonfire. Once you're ready, head through the misty door to face the Skeleton Lords.

BOSS: SKELETON LORDS

Upon entering the room you will see three Skeleton Lords. They all share the same life bar.

The Skeleton Lord on the right and the one on the left carry scythes while the Skeleton Lord in the middle has a large bone staff and casts pyromancies. Upon getting into melee range with this Skeleton Lord, he will try to bash you with the staff.

Once you enter the boss room, run at the Skeleton Lord of your choosing and get as many hits in as possible before they reach the ground. If you are unable to kill your target before it touches the ground, kite all the Lords around the room and make sure you aren't surrounded. Use the pillars around the room to your advantage as they can completely stop the middle Skeleton Lord's pyromancy. Don't get caught by both of the scythe-wielding Lords as they can stunlock and inflict massive damage.

Once one of the lords is dead, they will spawn skeleton minions which are easy to kill. These minions also share the same life bar along with the lords.

All of the skeletons in the room, Skeleton Lords and the smaller skeletons that spawn upon their respective Lord's death, are weak to fire. Bringing a Fire weapon and/or Pyromancies will make the fight much easier.

After the battle, continue along the path and pull the lever to lower the bridge. Following this path will lead you towards Harvest Valley. If you haven't visited Undead Purgatory yet, now is the time to do it.
