Monster Train 2 is a deck-building game set in Heaven, which is split into Rings. You build and upgrade your cards between battles, and every Ring's combat ends with a boss. Bosses are big, tricky enemies with strong effects that can change how the whole fight plays out, and many come in several forms. Soul Savior, a separate mode from the Destiny of the Railforged DLC, has its own set of bosses and a different route through the game.

Standard Run Bosses by Ring
In standard runs, the kind of boss changes as you move up the Rings. Rings 1, 2, 4, 5 and 7 hold minor bosses, which are regular enemies that appear on the final wave of their fight with the Relentless effect. Rings 3, 6 and 8 hold the major bosses, and Ring 9 holds the Titans.
Ring 3 is home to Arkion and Fleshweaver, Ring 6 has Cael and the Stryx and Hallow pair, and Ring 8 brings the Seraph Aeternus forms. Ring 9 sits outside the regular climb. It only opens once you have collected every Titan Essence, and fighting it after Ring 8 is an optional extra battle that gives a higher score and extra unlocks.
Standard boss stats also depend on your Covenant Rank. Health generally climbs as the rank goes up, and Attack often rises too. That means the same boss can hit harder at a higher rank.
Flying Bosses and How They Move
Most of the major bosses on Rings 3, 6 and 8 are flying bosses, so they don't stay on one floor. Stryx is also a major boss, but its movement is different.
A flying boss doesn't wait for the final wave. It appears on turn 1 and moves to a different floor after every turn, and it only becomes a regular, non-flying boss with the Relentless effect once the final wave starts.
On turn 1, it appears on the highest floor that already has your units during deployment. If you've placed units on every floor, it starts on the top floor. Units summoned at the start of turn 1 by certain artifacts don't count toward this.
After each turn, the boss prefers to fly to a floor that has your units. When all three floors stay occupied, its route settles into a repeating loop that always moves either up the floors or down them. If only one or two floors have your units, it keeps returning to them.
That makes your deployment a real choice. If you want to face the boss on your main unit floor as often as possible, occupy only one or two floors. If you want to face it there as rarely as possible, as you would against Seraph Aeternus-The Dominant, fill all three floors.
Once the Relentless phase begins, some effects switch off. Arkion's triggers stop working, though his Furious Frenzy form keeps any Rage it has built, and Seraph Aeternus-The Dominant stops applying Corruption to all your units with its action while still doubling Corruption on the unit it attacks. Most other effects keep working.
Boss Effects to Plan For
Boss effects fall into a few broad groups, and knowing which one you're facing shapes how you prepare.
Some bosses punish you for hitting them. Legion starts with Spikes, so every hit on it hurts the attacker. Quoto the Absolute begins with heavy Titanskin that drops each time it's struck, and Fleshweaver loses Mass when hit and creates Fleshlings.
Others wear down your units over time. Ajax the Unyielding keeps applying Sap, which steadily lowers the Attack of your units, and Qel the Corruptor adds Corruption to your units whenever you play a spell on its floor. Dominion, one of the Titans, adds Corruption to your front unit on every floor.
Still others get stronger as the fight goes on. Elebor the Wall piles on Armor during the fight, and Yorael the First-Blessed builds Rage each time it slays a unit. The Undying One uses Reanimate to stretch its fight, and Rax the Overblessed gains Rage, Regen and Spell Shield every time it resolves.
Some bosses bring their own helpers. Cael summons Cherubs that grant effects when eaten, and Athane, Last to Fall summons a Chosen Prayerstone.
Others reach into your deck. Entropy adds a Curse of Entropy card to your deck each time it resolves, and the Entropic form of Seraph Aeternus does the same.
Bosses That Matter Most
Some bosses stand out for their numbers, and others for how their fights unfold. The Entropic form of Seraph Aeternus on Ring 8 has the highest Attack and Health of any standard boss. The other forms on Ring 8 play very differently, so it helps to know which one you're facing.
The Titans on Ring 9 each fight in their own way. Dominion stays put by the Pyre, and Entropy never moves while having both the most Attack and the most Health of the Titans. Savagery tramples through your units and can damage the Pyre directly when its floor is empty.
Stryx and Hallow share one fight on Ring 6, and each one makes the other stronger. Hallow's effects keep adding Health to Stryx, while Stryx's effects keep adding Attack to Hallow, so the pair can grow stronger as the fight goes on.
How Soul Savior Bosses Work
Soul Savior runs start with a first battle against Astrael, the First Reborn. After that, the regions can be cleared in any order, and each region ends with a battle against its boss. The run finishes with a final battle once the regions are done.
Soul Savior has its own difficulty levels, labeled Bloom, Tangle and Overgrowth, and boss numbers rise with each one. Region bosses also grow stronger as you complete more regions, so the ones you face later in a run tend to be tougher.
Some Soul Savior bosses share a name with a standard boss, such as Korin, Athane, Qel and Quoto, but they are separate enemies with their own stats and abilities. Treat each one as its own fight, even if the name looks familiar.
Soul Savior Region Bosses
Each region offers a choice of first-combat boss, and its major boss waits at the end. In Maera's Region you can meet Athane the Fallen or Korin the Judged. In Thaddeus's Region it's Elebor the Unstoppable or Quoto the Destroyer, in Tivi's Region it's Phalanx or The Undying Spirit, and in Lylith's Region it's Ajax the Deathbringer or Qel the Malaiser.
Every region's major boss is a flying boss, and each comes in forms built around a theme. Maera the Dutiful's forms hand out Armor, Rage or Burst to the enemy units around her, and Thaddeus the Indulgent's forms work through floor Capacity and Gorge. Tivi the Unruly's forms copy enemy units, advance your units or add Scourge cards to your hand, and Lylith the Spurned's forms use Dualism, Witherbloom or Armor.
FAQ
Do you still get a Boss Artifact for beating a Soul Savior boss?
No. In Soul Savior, a boss kill gives you an extra Soul instead of the Boss Artifact you'd receive in a standard run.
What happens after you beat a Soul Savior region boss?
You receive a negative mutator, and one central map node in every other region is permanently upgraded to a stronger "+" version. Once you've beaten the bosses of all but one region, every central node in the last region has been upgraded.
Can you move flying bosses with Advance, Retreat or Rooted?
Not with those effects. Flying bosses are immune to Advance, Retreat and Rooted, but Ascend and Descend can still move them. Ascend can't push one into the Pyre room before its Relentless phase, and a forced move can flip its flight pattern.
How long does a flying boss keep flying before the Relentless phase?
In the Arkion and Fleshweaver fights, the boss gets 5 flying turns before the Relentless phase. In the Cael, Stryx and Hallow, and Seraph Aeternus fights, it gets 7.
