Travel to the Undead Lockaway bonfire in Huntsman's Copse. Head out of the room and across the stone bridge to the right. You've already been down this path before, but now you're heading to Harvest Valley. Follow the path, taking down the enemies as they appear. Take the first fork to the left, kill the enemies and pick up the item on the ground in the middle of the open area to obtain 10 Poison Throwing Knives.
Drop down to the path below, or head back the way you came and turn left at the fork to get to the lower path. Make your way to the waterfall and head down the path to the right of the blocked doorway. Circle all the way around until you see a cave on the left.
Enter the cave and take down the skeletons inside. Pick up the three Flame Butterflies and pull the lever at the end to connect both halves of the cave, then return to the waterfall. Head up the stairs directly under the waterfall and enter the mist to engage the Skeleton Lords.
Boss Battle: Skeleton Lords
Reward: Skeleton Lord's Soul
The Skeleton Lords boss battle consists of three main skeletons that go down fairly quickly, then a horde of weaker skeletons that go down even faster, but are much larger in number. As soon as you enter the boss arena, head straight for the first Skeleton Lord and take it down quickly. You should be able to kill it before the other Skeleton Lords give you much trouble. Do the same to the next two Skeleton Lords, but as you attack one, keep the other in sight so you can evade any ranged attacks.
Once all three Skeleton Lords are down, target the weaker skeletons with wheels first. These are the most troublesome enemies in the battle. They race toward you on the wheels and inflict considerable damage. They should be taken down quickly, but stay on the move and keep as many of them as possible within view. If they race towards you, dodge out of the way to avoid taking damage.
Defeat the mobile skeletons, then focus on the remaining enemies. Don't try to fight them all at once, instead continue moving around so you can battle small groups. This makes the last portion of this fight much easier to deal with.
With the enemies down, head through the doorway to the right of the entrance. Continue down the corridor to the right and pull the lever at the end to lower the bridge. Head across the bridge and through the corridor, then down the ladder at the end. Continue down the path into Harvest Valley.
