Undead Settlement - way down Dark Souls III Guide

Remember: There are two ways to get to this place. The presented solution suggests jumping down in this specific spot (see screenshot). You can get here on your way to the cathedral (from the arena go through a large grassland and turn left to the stone bridge - it's one of many paths that lead to this place). If you have the right armor and a lot of health points, you may try to slowly slide down, right behind the presented NPC. Although you will lose a significant amount of HP, it is still possible to survive this journey.

Talk to Irina and unlock the passage.

Head right, into the mountain and watch out for rats that will appear suddenly inside the room (kill them by the den so they won't spread too much). Go upstairs (there is Saint's Talisman near the ladder). You can unlock bars on the right, and thus avoid the trouble of having to jump down in the future. Irina is on your left. Talk with her (allow her to touch you) to obtain Prayer gesture. Finish the conversation and she will travel to Cleansing Chapel.

Remember: When you are directly in front of the place where you meet Irina, look up. There is a body that can be shot down (or use a Firebomb). It contains Sacred Red and White Shield +1.

Deal with your enemies and pick up items.

Get back to the pit if you want to explore this location some more. Watch out for two opponents at the crossroads. Turn left and run after the crystal lizard - if you kill it, you will receive Heavy Gem. Apart from that, look for 2x Titanite Shard.

Strike bones before they join and form an enemy.

Use the corridor that goes under the stone bridge. Look out for skeletons that are created from scattered bones (try to attack quickly before they join together). Move forward and you will come across a Soul of an Unknown Traveler, Red Hilted Halberd and Loincloth, next to a Statue of Velka. The door can be opened from the other side, and this is the other way you can get to the pit.

Here you will find the required item.

You need Mortician's Ashes. To find them, head to the Dilapidated Bridge bonfire, in the direction where a graveyard is located (there are tombs on the left). Watch out for projectiles (if you talked with the giant from the cathedral, you will be safe). Face the tree with a note on it (in front of the building), and turn left. The item you are looking for is not far from here, between the tombs. Take it to Shrine Handmaid, and buy a Grave Key for 1500 souls (it will be added to your inventory once you retrieve the ashes).

Entrance in the dungeons (on the right).

Now that you have the key, head to the dungeons. The entrance is at the previously described square full of enemies (if you unlocked this shortcut before, the other entrance is situated behind the stone bridge, opposite the Dilapidated Bridge bonfire). Use the key to unlock the bars. The process of exploring the lower part of the location is identical - the only difference that you will notice is the order of enemies and items that you will come across.

Once the entire area has been searched, head to the arena and face Curse-Rotten Greatwood. Once you deal with it, get back to the lift in the cathedral and use it to reach the bottom. The exit will take you to Road of Sacrifices.
