Where to find the Enhanced Map in Mina the Hollower
The Enhanced Map is sold by Drillhardt inside the Ossex: Hollower’s Guild. Before you can access this merchant, you’ll need to progress through the early game and complete the rescue sequence involving Rhene.

After reaching Ossex and entering the Guild area, Rhene will help restore parts of the facility, allowing new services and vendors to appear. Drillhardt becomes available shortly afterward and sells the standard Isle Map first, followed later by the Enhanced Map.
Requirements for Enhanced Map unlock – Rescue Rhene
To unlock the Enhanced Map, you must first complete several steps tied to the game’s early progression. Here is how to rescue Rhene and get enhanced map in Mina the Hollower:
Step 1
Travel to the Southern Outskirts and locate the building where Rhene is being held by Thorne’s forces. She will be surrounded by enemies and unable to escape on her own.

Step 2
Heal Rhene when prompted. Your Plasma healing ability can be used to restore her health and allow her to move.

Step 3
Escort her through the dangerous rooms filled with enemies and environmental hazards. If she takes damage, she may panic and stop following properly, so clear threats quickly.

Step 4
Complete the final puzzle room by burrowing beneath obstacles and activating switches that remove spike barriers. Continue guiding Rhene until she safely escapes.

Step 5
Meet Rhene later at the Hollower’s Guild, where she restores parts of the facility and unlocks access to new features and vendors.

Buying the standard Map first
Before purchasing the Enhanced Map, most players will acquire the standard Isle Map from Drillhardt for 500 Bones. The regular map provides a broad overview of Tenebrous Isle and can be viewed from Mina’s Underlab safe area. It helps with general navigation but does not display individual rooms or detailed collectible locations.

What the Enhanced Map actually does
Many players expect the Enhanced Map to reveal more terrain or add a detailed minimap. However, that is not its purpose.

Instead, the Enhanced Map unlocks regional completion tracking. Once obtained, it displays checklists and collectible counts for each area, allowing you to see how many important items you have already found and how many remain undiscovered. This makes it significantly easier to revisit regions and finish collecting upgrades, treasures, and other hidden content.
Why the Enhanced Map is worth buying
The world of Tenebrous Isle is packed with secrets, optional upgrades, hidden passages, and collectibles. As the game progresses, it becomes increasingly difficult to remember which regions still contain missing rewards.

The Enhanced Map solves this problem by giving you a clear overview of your completion status. Rather than searching every area blindly, you can identify zones where collectibles are still missing and focus your exploration there. This is especially useful if you’re aiming for 100% completion or trying to find every upgrade before entering the late game.
| Benefit | Description |
|---|---|
| Regional Checklists | Shows completion information for areas |
| Collectible Tracking | Helps identify missing items |
| Exploration Assistance | Makes backtracking more efficient |
| Completion Support | Essential for 100% runs |
| Better Progress Monitoring | Lets you see which regions need further exploration |
If your goal is simply finishing the main story, the standard Isle Map may be enough. However, if you plan to uncover every secret, collect every upgrade, and fully explore Tenebrous Isle, the Enhanced Map is well worth the 500 Bones investment. Its regional checklist system saves a huge amount of time and helps ensure you don’t miss important collectibles hidden throughout the game’s sprawling world.
