Learn how to unlock Pyre Hearts in Monster Train 2 to access Dimensional Challenges, new mechanics, and strategic gameplay options.

If you are trying to progress in Monster Train 2 but the Dimensional Portal stays closed, it’s likely because you haven’t met the requirements involving Pyre Hearts. These are more than just modifiers, they’re tied directly to unlocking the story’s next phase and accessing harder modes. Each Pyre Heart adds variety to your strategy. Some affect unit boosts, others impact how you approach battles. Unlocking them changes your decision-making before and during each run.
Here’s a guide to help you get those crucial unlocks quickly and without confusion.
What Do You Need To Unlock Pyre Heart in Monster Train 2?
You can preview every Pyre Heart’s status before a run begins. On the setup screen, click the Pyre Heart icon. This brings up all the locked and unlocked hearts, along with the requirements to activate each one. It also lets you pick which Pyre Heart to use for that run.
If you are not ready to start a new game but still want to review your progress, use the in-game Library. It’s a helpful place to revisit requirements between attempts.
Three Pyre Hearts To Unlock

To open the Dimensional Portal and access deeper gameplay layers, you need to unlock any two of these three Pyre Hearts in Monster Train 2. You don’t have to get them all at once; just choose which goals suit your style and work through them.
Lifemother’s Pyre
To unlock Lifemother’s Pyre, take 475 total Pyre damage across all your runs. Any damage to your Pyre counts. If you want to speed things up, launching quick runs and letting them fail can help. It’s not pretty, but it gets the job done.
Heart of the Pact
At the start of most encounters, a Trial option appears. Activating it increases challenge while offering better rewards. You need to secure nine victories while Trials are active. No need to achieve all nine wins in one run, progress carries over. This objective appeals to those comfortable with higher risks and tougher battles.
Wyngh’s Spirit
You have to shift units across the battlefield 275 times. Each time a unit changes position during combat, it adds to your total, whether through card effects, abilities, or manual swaps. Over time, this tends to complete naturally, especially during longer runs. Even inefficient or unnecessary shifts still count toward the goal.
Why Pyre Hearts in Monster Train 2 Matter
In Monster Train 2, unlocking any two Pyre Hearts grants access to the Dimensional Portal. This feature introduces Dimensional Challenges. Though the difficulty rises, the rewards improve as well, offering valuable advantages in later runs.
Alongside this, Malicka’s Shifting Pyre becomes available. This particular Pyre Heart enhances every unit you recruit, altering their effectiveness in combat.
