Mina the Hollower Hidden Mechanics
Mina the Hollower explains its basic controls well, but several combat, movement, equipment, and New Game Plus systems are easy to misunderstand. This guide focuses on mechanics that meaningfully change how you dodge, explore, manage resources, and recover missed items.

Quick Answer
The most useful hidden mechanics are not secret cheat codes. They are small rules the game does not always explain clearly: burrowing is a timed defensive action rather than permanent invulnerability, Trinkets can change the way resources and movement behave, some missed purchases can be recovered later, and NG+ uses a large modifier system rather than a simple enemy-health increase.
1 Burrowing Is a Timed Dodge, Not Permanent Safety
Burrowing is Mina's core defensive movement tool, but entering the ground does not automatically make every situation safe. The useful part is the timing: many attacks can be avoided by moving underground before the hit connects, then surfacing after the dangerous part of the animation has passed.
This matters most against attacks with a clear startup and a narrow active window. Burrowing too early can leave you surfacing into the follow-up, while burrowing too late can still result in damage before Mina is fully protected.
Practical timing rule
- Watch the enemy animation rather than Mina's position alone.
- Burrow just before the active hit, not at the beginning of every windup.
- Delay the surface when the attack has a lingering area or second swing.
- Use open ground to practice before relying on the timing in a boss fight.
2 Some Modifiers Change Burrowing More Than Trinkets Do
New Game Plus and modifier presets can alter the normal burrow rules. For example, the modifier list includes effects such as Invulnerable Burrow, which causes burrowing to ignore damage, and Burrow Chain, which allows one burrow jump to lead directly into another.
These options should not be confused with the default rules of a normal playthrough. A strategy that feels completely safe under an assistance or modifier preset may not work the same way with standard settings.
Why this causes confusion
Players often compare experiences without mentioning active modifiers. When two people report different burrow behavior, first check whether either run uses an accessibility preset, NG+ preset, or individual gameplay modifier.
3 Plasma Effects Can Change the Value of an Entire Build
Plasma is not only a resource to spend. Certain equipment and modifiers can change how much Plasma you can hold, how it is gained, or what it does. That means a Trinket that looks average in a normal setup can become much stronger when the rest of the build supports the same resource loop.
The important lesson is to evaluate Plasma-related equipment as a package. Extra capacity has limited value when the build cannot fill it, and faster gain has limited value when there is no useful way to spend the resource.
Questions to ask before using a Plasma build
- Can the route or boss reliably provide enough Plasma?
- Does the Sidearm convert the extra resource into useful damage or control?
- Does the build still work when Plasma drops to zero?
- Are you sacrificing too much defense for a resource loop that is not always active?
4 Upgraded Trinket Forms Are Not Always Separate Collection Slots
Some equipment can change into an upgraded form after completing a requirement or returning to the relevant character. A key example is the relationship between Glutton's Jug and Plasma Jug.
Plasma Jug should be treated as the upgraded form in that progression path, not automatically counted as an unrelated extra pickup. This distinction matters when checking collection totals and when building a cleanup checklist.
Why upgrade forms matter
- They can change the effect of an item you already own.
- They may require a kill count, quest step, or return visit.
- They can create apparent collection-count mismatches.
- They should be documented separately without being mistaken for a new standard slot.
5 The Black Market Can Recover Some Missed Opportunities
Missing an item at its first opportunity does not always mean the entire save is ruined. Some items can become available through the Black Market after their relevant unlock condition has been met.
This is especially important during 100% cleanup. Before restarting the game or assuming an item is permanently missable, check the Black Market and confirm whether the original condition was completed.
Cleanup order
- Confirm the item's original unlock condition.
- Complete the required quest, encounter, or progression step.
- Revisit the Black Market after the condition is satisfied.
- Check the dedicated item page before declaring the pickup permanently missed.
See the Black Market Trinkets guide for a focused cleanup route.
6 NG+ Is a Modifier System, Not Just a Health Increase
New Game Plus can change far more than enemy durability. The game includes a broad modifier menu with harder, easier, unusual, starter, cosmetic, and display-oriented effects. Presets can combine multiple modifiers, while individual settings can alter movement, damage, resources, checkpoints, equipment availability, and other world rules.
This means two NG+ runs can feel dramatically different even when both are described simply as “NG+.” When sharing a route, build, or challenge strategy, list the active preset or important modifiers.
Examples of systems modifiers can affect
- Damage taken and invulnerability duration
- Burrow behavior and movement rules
- Health, Joules, Plasma, and healing
- Starting weapons and equipment access
- Underlabs and boss checkpoints
- Economy, shop prices, and item availability
How to Test a Hidden Mechanic Reliably
Community descriptions can become inaccurate when patches, equipment, and modifiers are mixed together. For reliable testing, change one variable at a time: use the same enemy, the same room, the same equipment, and the same modifier settings.
Record whether the result is consistent across several attempts. A single lucky dodge or unusual enemy animation is not enough to prove a mechanic.
Hidden Mechanics FAQ
Is Mina invincible for the entire time she is underground?
Do not assume permanent safety under the normal rules. Burrowing is best treated as a timed defensive action. Specific modifiers can change its behavior.
Is Plasma Jug a separate Trinket from Glutton's Jug?
It is an upgraded form in the same progression path. Documenting both forms is useful, but it should not automatically be treated as an unrelated additional collection slot.
Can missed Trinkets always be purchased later?
No. The Black Market can help recover some missed opportunities, but availability depends on the specific item and its unlock condition. Check the dedicated item guide before relying on it.
Does every NG+ run use the same rules?
No. Presets and individual modifiers can produce very different movement, combat, economy, and progression rules.
Are all community-reported interactions confirmed?
No. Some reports mix default mechanics with equipment effects or active modifiers. Re-test uncertain claims under controlled settings.
