Pharros Lockstone is a type of consumable in Dark Souls 2.
- Unlock Pharros' Contraptions in:
- Forest of Fallen Giants:
- No-Man's Wharf:
- Lost Bastille:
- Opens passage to Belfry Luna, accessed by the Servant's Quarters bonfire in the Lost Bastille, go down a ladder and hit the revealed wall upon placement.
- One in the room with the twinblade chest, reveals room with a Soul Vessel, and another room which is already accessible via an elevator (the elevator room is revealed by default in SotFS).
- Earthen Peak:
- In Earthen Peak before first boss, at the very bottom in a room off a poison mist floor - Has Poisonbite Ring and Soul of a Proud Knight.
- Spill out poison to a small pool in Earthen Peak (area near 2nd boss, with a lot's of mushrooms and mimic chest). Becomes water that cures poison and gradually heals after burning the windmill.
- Iron Keep:
- Three in Iron Keep. Two spill out water to a small pool and lets player get wet and survive the lava to get the items and chests. The two that add water will also heal slowly over time if the player stands in the water. Third opens Belfry Sol and bonfire.
- Doors of Pharros:
- There are several (10-20) doors that can be opened in Doors of Pharros. Most of these lockstones will activate various traps, and unleash more enemies. The doors containing Mastodon Guards require 3 lockstones to fully open and let them out, it also has Santier's Spear behind it. The underwater middle lockstone will effectively open the passage by itself without letting out the guard.
- Grave of Saints:
- Lowers two different bridges in Grave of Saints that lead to the same room. Across the bridge there is Poison Moss x2 and a skeleton with Whisper of Despair and a Torch. If you put them in the sockets by the rat statues while part of the Rat King Covenant, you will unleash a pool of corrosive acid that lingers indefinitely and breaks down equipment within seconds. If you put a lockstone in the contraption to your left as soon as you come up the first set of stairs at the beginning, it will turn out all the torches down the hall. Putting a lockstone in the contraption that is on the wall, it will start pouring water everywhere that will put out your torch.
- Shrine of Amana:
- Just after the second bonfire, Crumbled Ruins. In the water near the ramp structure just past the first Amana priestess. Standing at the base of the ramp and facing the dragonrider in the distance, it's just to your left. Reveals a hidden cave in the cliffside with a chest containing the Helix Halberd.

- In the first area of the Dragon Shrine, on the floor under some boxes, behind the first knight. Reveals a hidden wall with the Judgement set and staff.
- Memory of Orro:
- There are two in one of the Giant Memories (Memory of Orro - located after the pursuer fight). The first shows an illusory wall you can attack to get through. The second, located past this illusory wall, is pointless and activates a trap. The true entrance to the treasure room is a regular illusory wall next to it. This room contains the Steel Armour Set and a Fire Seed.

- (Farmable) small rats inside of "Royal Rat Authority" boss in the doors of Pharros. Kill the small rats and then either die or use a homeward bone / feather to port back to the bonfire to reset the fight. upon resetting the fight, the small rats respawn.
- All lockstone's locations
- Rats in the water in Doors of Pharros. (Rare drop)
- Joining the Rat King Covenant and killing intruders, or being summoned as a grey phantom as an intruder to the Rat King Covenant and beating the host grants you one lockstone or running to the bonfire before the host kills you also gets you one.
- Doors unlocked by lockstones reset upon entering NG+.
- Pharros' Lockstone contraptions do not seem to be reset by using a Bonfire Ascetic. However, some chests will be reset with whatever item they previously contained. In other words, the loot respawns, but you do not need another Lockstone to access it. Bear in mind that this does not happen for all chests located behind Pharros' Lockstone walls. Only wooden chests and mimics are respawned by Bonfire Ascetics. Metal chests require an actual NG+ activation to respawn.
- Some Pharros' Lockstone contraptions, particularly those located at Grave of Saints can only be reset by using a Bonfire Ascetic at Majula bonfire.
- Using a Pharros' Lockstone while being summoned may consume the lockstone and render the contraption unusable. Seems to only happen to contraptions that have animations, like the doors in Doors of Pharros or the bridges in the Grave of Saints.
