What to know
- Proto Spark grants a one-time death save, automatically preventing a fatal death.
- The trinket resets after you die, allowing it to be used again on future lives.
- It is obtained in Queensbury Crypt through The Duke’s side quest, not from a chest or shop.
- You must locate and escort The Duke to his final resting place before claiming the reward.
Mina the Hollower hides several powerful trinkets behind side quests, and Proto Spark is arguably one of the best. Rather than increasing damage or mobility, it provides something even more valuable during difficult boss fights: a second chance. The trinket is tied to The Duke’s questline inside Queensbury Crypt and can easily be missed if you do not fully complete the NPC encounter.

Where to find Proto Spark in Mina the Hollower
The entire quest takes place in Queensbury Crypt. After progressing through the crypt, you will encounter The Duke, an NPC who needs assistance reaching his final destination. Instead of simply speaking to him and receiving a reward, you must guide him through the crypt and eventually bring him to a tomb where his story concludes.

How to get Proto Spark Trinket in Mina the Hollower
Step 1
Reach and clear the main sections of Queensbury Crypt, including the boss area associated with the dungeon progression.

Step 2
Locate The Duke within the crypt. Speak with him and begin his escort sequence.

Step 3
Guide The Duke through the required route toward his final resting place. Be careful of enemies and environmental hazards during the journey, as losing track of the NPC may force additional backtracking.

Step 4
Bring The Duke to the tomb located beyond the boss-room area of Queensbury Crypt. The quest only progresses once he reaches the correct destination.

Step 5
Interact with the tomb and perform the final sealing event. After The Duke is laid to rest, the quest ends and Proto Spark becomes your reward.

Proto Spark trinket effect explained
Proto Spark’s effect is simple but incredibly powerful:
| Effect | Description |
|---|---|
| Second Chance | Saves you from a fatal death once |
| Recharge Method | Resets after death |
| Best Use | Boss fights and difficult exploration sections |
Unlike many trinkets that offer small stat bonuses, Proto Spark can completely change the outcome of a difficult encounter. If a boss lands a killing blow, the trinket activates and prevents the run from ending immediately. Because it refreshes after each death cycle, many players consider it one of the best defensive trinkets available.

Why Proto Spark is worth getting
Many late-game enemies and bosses can eliminate a large portion of your health in a single mistake. Proto Spark provides valuable insurance against those moments, especially when learning boss patterns or exploring unfamiliar areas. Several community guides specifically highlight it as one of the highest-priority trinkets to obtain as soon as Queensbury Crypt becomes available.
To get Proto Spark, travel to Queensbury Crypt, find The Duke, escort him from the crypt’s boss-room area to his designated tomb, and complete the burial/sealing sequence. Finishing this side quest rewards one of the strongest defensive trinkets in the game, giving you a reliable second chance whenever a fatal mistake would otherwise end your run.
