Mina the Hollower is filled with hidden secrets, but one of the most interesting discoveries players have found is a secret transformation that occurs when you equip every Beastium Trinket at once. While each Beastium Trinket individually grants a powerful effect with a corresponding drawback, combining the entire set unlocks a unique Beast Form that many players can easily miss during a normal playthrough.
| Feature | Details |
|---|---|
| Secret Unlock | Equip all Beastium Trinkets simultaneously |
| Trinket Slots Required | 6 total slots |
| Transformation | Beast Form |
| Visual Change | Mina gains a beast-like appearance |
| Gameplay Impact | Combines multiple Beastium effects |
| Difficulty | High-risk, high-reward build |
| Missable? | Yes, if you don’t collect every Beastium Trinket |
Which Beastium Trinkets are required?
To activate the hidden transformation, you must equip all six Beastium Trinkets together:
| Beastium Trinket | Effect |
|---|---|
| Starving Beastium | Vials restore Joules but heal less |
| Warding Beastium | Reduced damage taken, weaker healing |
| Reckless Beastium | Increased attack power after healing but lower defenses |
| Draining Beastium | Stronger Sidearms with higher Joule cost |
| Volatile Beastium | Enemies can drop bombs on death |
| Burning Beastium | Fireballs appear when taking damage |
These Trinkets are scattered throughout the world and are generally found during mid- to late-game progression.

Why you need all six Trinket slots
The transformation cannot be activated until you unlock every Trinket slot available in the game. Mina begins with only one slot, and additional slots are obtained through Trinket Bags found or purchased throughout the adventure. By the end of the game, you can reach a maximum of six Trinket slots.

Without all six slots, it is impossible to equip the complete Beastium set.
How to trigger the secret Beast Form
Collect all six Beastium Trinkets. Unlock every Trinket Bag upgrade so you have six total Trinket slots available.

Open the Trinket menu. Equip Starving Beastium, Warding Beastium, Reckless Beastium, Draining Beastium, Volatile Beastium, and Burning Beastium together.
Exit the menu. As soon as the full set is equipped, Mina transforms into the hidden Beast Form.
What changes in Beast Form?

The most obvious change is Mina’s appearance. Her sprite becomes significantly more monstrous, reflecting the corrupted Beastium energy flowing through her.
The transformation is primarily a hidden easter egg and build synergy reward rather than a completely separate gameplay mode. The form effectively stacks the effects and penalties of every Beastium Trinket, creating a character capable of dealing massive damage while also managing numerous drawbacks.

Players using the form often notice:
| Benefit | Drawback |
|---|---|
| Higher offensive potential | Reduced healing efficiency |
| Stronger Sidearms | Increased resource consumption |
| Extra offensive effects from bombs and fireballs | Greater punishment for mistakes |
| Unique appearance | Difficult to sustain during long fights |
Because all Beastium modifiers are active simultaneously, the build becomes extremely aggressive and rewards skilled play.
Is Beast Form worth using?
For exploration and casual gameplay, Beast Form can be difficult to manage because several Beastium Trinkets reduce survivability or make resource management harder.
However, if you enjoy glass-cannon builds, boss challenges, or experimenting with hidden mechanics, Beast Form is one of the most entertaining secret loadouts in Mina the Hollower. The combination of offensive boosts, explosive effects, and the unique visual transformation makes it one of the game’s coolest hidden discoveries.

| Hidden Easter Egg Discovery | Completionist Reward |
How to revert to normal Mina form?
To return to normal from the secret Beast Form in Mina the Hollower, simply use a Plasma Vial again while transformed. The same action that triggers the transformation also toggles it off, reverting Mina to her standard form immediately. Community testing of the Beastium Convergence mechanic confirms that a second vial use cancels the transformation.

If it doesn’t work, make sure you still have all six Beastium trinkets equipped and enough resources to use a Plasma Vial. Some players also report accidentally triggering other vial-related effects from equipped trinkets, but the intended method to exit Beast Form is just another Plasma Vial use.
So the sequence is:
Equip all six Beastium trinkets → Use Plasma Vial → Enter Beast Form → Use Plasma Vial again → Return to normal.
The Beastium Trinkets appear to be designed as corrupted power sources that grant significant advantages at a cost. Equipping a single Beastium Trinket creates a specialized build, but equipping the entire set represents Mina fully embracing Beastium power. The resulting Beast Form serves as a hidden reward for players who collect every Beastium relic and invest in all six Trinket slots.
For completionists, it is one of the most satisfying secrets in the game because it ties together multiple late-game collectibles into a single transformation that many players may never discover on their own.
Equipping all the Beastium trinkets sounds intense. How does it change gameplay dynamics?
