A Healer's Mercy Quest Guide & Dungeon Key Location in Phantom Blade Zero

Quest Overview & Requirements

"A Healer's Mercy" is a side quest located in the Crimson Forest region of Phantom Blade Zero. To begin this task, you must travel to the Thieves Camp and speak with Yura. During your conversation, choose the dialogue option regarding the wounded in the woods.

Accepting this quest initiates a search for four injured thieves scattered across the map who require medical attention. Completing the entire operation requires exploring hidden cave systems, unlocking doors using specific keys, and navigating through guarded outposts.

Step 1: Locating the First Wounded Thief

To reach the first target efficiently, fast travel to the Outlaw Trap, which serves as the closest starting point for this objective:

1. From the Outlaw Trap fast travel marker, head toward the west.
2. Press the mind's eye button if necessary to confirm the proper direction down the pathway.
3. Run down the path until you discover the first injured thief lying on the ground.
4. Interact with the individual to administer the life-saving pill.
5. Search the surrounding area just beyond this location to collect valuable loot items, which will be useful for subsequent phases.

Step 2: Finding the Second Thief in the Cave

The second target appears deceptively distant on the overworld map, but the actual path is surprisingly short:

1. Return to the Outlaw Trap fast travel point.
2. Locate the nearby device and insert the crank to open access into the underground cave system.
3. Descend into the cave and cross the wooden bridge leading toward the table.
4. Look just beyond the table on the left side to locate the second wounded thief.
5. Interact with the character and administer a schedule one pill, bringing your total of healed thieves to two out of four.
6. Make your way back up to the surface and return to the fast travel points.

Step 3: Acquiring the Key and Locating the Third Thief

The final two targets require traveling a significant distance across the map, starting from the Thieves Camp:

1. Depart from the Thieves Camp by following the road around the corner in a generally straight line.
2. Gather loot along the path, travel through a cave, and crouch to exit on the opposite side into a small village with a locked door.
3. Turn around, head up the stairs, and enter the large house on the left.
4. Loot the Forest Outpost Courtyard Key from the interior.
5. Return to the locked door, unlock it, and activate the resting point.
6. Follow the road uphill, exploring corners for loot, and eventually head down a section by jumping down and navigating forward toward a large house in the distance.
7. Veer to the left behind a tree to find a ladder leading down.
8. Descend the ladder to locate the third wounded thief at the bottom and heal them.

Step 4: Obtaining the Thieves Camp Dungeon Key

With the third thief treated, return upstairs via the ladder to access the main house and secure the final item required for the quest:

1. Navigate to the right-hand side of the house through an open hut to find a resting point and a ladder leading to the second floor.
2. Clear the obstacles at the top, clear the pathway to the left, sprint quickly through the poison area, and pick up the crank.
3. Jump down, use the crank in the nearby machine to open the cellar, and head underground.
4. Keep to the left open pathway while collecting loot, then jump across and ascend the section featuring a glowing item in the distance.
5. Collect the Thieves Camp Dungeon Key and prepare to fast travel.

Step 5: Healing the Final Thief and Claiming Rewards

The final objective brings you back to where the quest began:

1. Fast travel back to the Thieves Camp.
2. Locate the previously locked gate near the camp, which can now be unlocked using the Dungeon Key.
3. Enter the area and immediately check the left side to find the fourth and final wounded thief.
4. Interact with them to complete the requirements of the Healer's Mercy quest.
5. Return to Yura at the Thieves Camp village to discuss the wounded in the woods and claim your reward.
