Monster Train 2 features five new clans, each of which has its own unique mechanics, cards, and artifacts. That is not the end of the story, though, as it is actually possible to unlock five clans from the previous game. More specifically, players can unlock the Hellhorned, Awoken, Stygian Guard, Umbra, and Melting Remnant in Monster Train 2, and this guide explains exactly how that is done.

The Wurmkin is the only clan from Monster Train that is not currently available in the sequel.

How to Unlock Old Clans in Monster Train 2

Unlock Six Pyre Hearts

The first step towards unlocking the old clans in Monster Train 2 is unlocking six Pyre Hearts. For full clarity, Pyre Hearts determine the stats and abilities of the pyre at the top of the train, and there are 13 of them in total.

With respect to how Pyre Hearts are unlocked, each one has its own requirements, from winning battles with trials, to winning a Dimensional Challenge, and beyond. Players can check the unlock requirements for each Pyre Heart, and track their progress, by taking these actions:

  • Click "Depart" and start a new run.
  • Click on Pyre Heart selection on the left side of the screen, just below Allied Clan selection.
  • Hover over the locked Pyre Hearts.

While players should expect to unlock Pyre Hearts simply by playing Monster Train 2, they could expedite the process by sticking to low Covenant Ranks and focusing specifically on fulfilling unlock requirements. Indeed, the majority of the Pyre Hearts can be obtained without ever winning a run or trying out higher levels of difficulty, and players will gain access to the Hellhorned clan as soon as the sixth one is unlocked.

Unlock Awoken, Stygian Guard, Umbra, and Melting Remnant

After unlocking six Pyre Hearts and the Hellhorned clan, Monster Train 2 players need to fulfill specific requirements to unlock the remaining old clans. Those requirements are as follows, and, once again, fulfilling them is not contingent upon winning runs:

  • Awoken: Heal 300 lost health. This can be most easily done with the Luan Coven, and the Wyngh's Spirit Pyre Heart can assist with the endeavor.
  • Stygian Guard: Cast five spells in a turn five times. The Luna Coven's Moon Ritual and Witchweave spells are great for fulfilling this requirement.
  • Umbra: Increase room capacity 20 times. Selecting Heaven's Light after beating bosses is the most obvious way to approach this one, though the Bogwurm's Growth Pyre Heart can also help.
  • Melting Remnant: Reanimate or Reform 50 units. Players who take the Lazarus League into battle should have no trouble unlocking this old clan.

Players can check their progress towards fulfilling these requirements through Primary or Allied Clan selection when setting up a new run.
