Monster Train News

Mod support launches October 22nd

**UPDATE** The stream time/date has changed. See below.

In just 8 days Monster Train will add official support for mods via Steam Workshop in the Herzal's Workshop update. As you might already have seen during our weekly streams, Mark from Shiny Shoe has been playing mods, creating mods for Monster Train live, showing off official developer example mods, and has even shared a few Halloween surprises. On October 16th at 10 am Pacific we will have community modder Chronometrics on the stream to show you how to create your own custom Monster Train card and answer any questions on the process. Follow here and watch.



On October 22nd at launch, we will have several mods available made by the development team and the community and we look forward to seeing where creativity takes you if you decide to make your own mod. As a modder, you can really change or add almost anything you like to the game, from quality of life improvements like the “restart battle button" to a whole new clan! We can’t wait to see what you think of the mods waiting for you in the Steam Workshop. But even if you’re focused on just enjoying the new content, we look forward to seeing the possibilities for new cards, monsters, cosmetic and game-changing benefits for all players.

Halloween is fast approaching and to celebrate Monster Train will feature festive decorations plus something incredibly special you’ve all been begging for. The card Bone Dog’s Favor is one of the most sought after in the game because the chances of it appearing are low. Now, we’ve slightly increased the appearance rate of the event permanently AND because he’s a Very Good Boy, Bone Dog gets his own standalone event. For a limited time, his chances of coming home with you significantly increase during the Halloween celebration. Drop-in and get your ultimate Pyre-restoring buddy during your run to really show Seraph who is boss.

When mod support goes live we will publish some documentation that explains the process to help you get started making your own mod.

Monster Train Patch 1.2.6

September 17, 2020
1.2.6 (10470)

This is a small update primarily focused on bug fixes and a few balance changes.

  1. GAMEPLAY - Trample can now be added to a unit that already has Trample. It doesn't do anything but it's a consistency improvement.
  2. GAMEPLAY - no longer open the deck UI if you cast Molded with no possible targets.
  3. GAMEPLAY - Molluscmage is now Common.
  4. GAMEPLAY - Titanstooth is now Uncommon.
  5. GAMEPLAY - Solgard's Titanchannel now has increased stats, 35->40 at level 1, 75->90 at level2 with an increased Shard requirement of 9->12, and 175->210 with an increased requirement of 12->15. The goal of these changes is to both increase the overall power level and also make the need to focus on casting many spells more prominent as you level up with path.
  6. GAMEPLAY - Little Fade's Fire Light path now adds +5 max health at all levels instead of the lower scaling amounts previously.
  7. GAMEPLAY - Little Fade's Eternal Flame at all levels now gives increased attack. Level 1 is 20->25, level 2 is 60->70, level 3 is 120->140.
  8. GAMEPLAY - Flicker's Liquor now ignores unplayable cards like Deadweight.
  9. TEXT - updated Cardless tooltip to mention Eaten pile.
  10. TEXT - improved Melee Weakness Seraph description.
  11. TEXT - changed description of Razorsharp Edge and Offering Monument to refer to max health specifically (again) to try to eliminate frequent confusion about how they behave.
  12. TEXT - changed description of Advanced Prototype to try to clarify that it doesn't work on Cardless units. Edge case that comes up with Hivemind and Commemorative Spike.
  13. TEXT - improved consistency in Portuguese.
  14. ART - updated one of the Darkshard portraits in battle intro to look more unique like it does in battle.
  15. ART - updated Primordium's face in clan select to improve visual quality.
  16. BUG FIX - fixed an issue with Hope for Peace and duplicating Purge cards that could result in Purge coming back.
  17. BUG FIX - fixed preview issue with Phased units.
  18. BUG FIX - fixed Sting art missing if you have Wyldenten as your champion via the mutator that selects a non-class champion and then you go the Sting path. This change fixed some other similar issues as well.
  19. BUG FIX - ensure Looming Darkshard's cost increase is applied in order with effects such as Split Anvil.
  20. BUG FIX - improve interaction between Wickless Recruitment and Fade's First Blade.
  21. BUG FIX - fixed a bunch of Hivemind issues introduced in the new content in the Friends & Foes update.
  22. BUG FIX - fixed wrong bosses being shown in run history for runs before the Friends & Foes update.
  23. BUG FIX - fixed softlock when using Yeetpocalypse with a deck with no more cards to purge.
  24. BUG FIX - sped up Little Fade's VFX so they fade out faster on death.
  25. BUG FIX - fixed interaction with Little Fade's Icarus path and the Highly Reactive mutator.
  26. BUG FIX - Solgard's Coldchannel path with Cuttlebeard does not apply Revenge if Solgard has 0 Shard.
  27. BUG FIX - fixed an issue where opening the Logbook with certain timing could prevent artifact effects from occurring in battle, including Covenant effects.
  28. BUG FIX - Acid Rain can no longer hit Phased units.
  29. BUG FIX - fixed issue where some cards didn't trigger Moth Magic correctly.

Friends & Foes Update - Available Now!

This second major update for Monster Train adds new champions, new bosses, new cards, and new artifacts, which combine together to add a significant amount of new strategic options and replayability. We’ve also added a number of frequently requested player features like a personal run records page in the Logbook, an enemy wave counter in battle, and a preview of the ring 3 and ring 6 bosses at the start of a run.

Major new features


Five new “Exiled” Champions, one from each of the monster clans. The new Champions have new mechanics, come with their own new starter card, and add additional layers of strategic depth and replayability.



Two new bosses at the 3rd and 6th ring of Hell, each with three variations. Talos and Archus join the fight as alternative options to Daedalus and Fel. These new bosses have brand new combat mechanics and increase run variety.



A new final boss variant - Seraph the Patient. This version of Seraph uses a new gameplay trigger, Rally, and applies Melee Weakness to your units.



Five new artifacts, one from each of the monster clans. Each adds new ways to gain power and synergize with clan mechanics.



Personal run records are now available for viewing the Logbook. Track your improvement over time and compare with friends!

  8. NEW BOSS - Seraph the Patient. A new Seraph variant that both attacks before the Relentless phase and applies Melee Weakness, a new status effect that increases combat vulnerability.

General Gameplay Changes:
  1. New keyword: Phased. Phased units cannot attack, cannot be targeted, and cannot take damage in any way.
  2. New keyword: Attuned. Spell cards with Attuned benefit from Magic Power at 5x the rate as normal. The goal is to increase late-game viability of certain cards.
  3. New keyword: Melee Weakness. When applied a unit takes more damage from normal combat.
  4. New trigger: Rally. Triggers when you play a unit card on this floor. Morsels do not trigger Rally.
  5. Action trigger (previously called “On Turn”) is now used on some new player units. Triggers on the unit's turn, before it attacks.
  6. GAMEPLAY - any unit that was Eaten now goes to a new Eaten card pile. Reform deals with dead units in the Consume pile and does not Reform from the Eaten pile. Retch pulls from the Eaten pile.

  8. Shieldstone Damage Shield stacks increased 2 -> 3.

  4. ENGINE - updated to Unity 2019.4.

We added a new option, Unity, because Unity 2019 supports hardware decoding of video. Using the Unity option allows muting video from Windows Volume Mixer to work correctly and it also works on Linux under Proton/Wine. Select the best option for your circumstances from the settings menu.
  6. UI - added ability to switch between Exiled and normal Champions for both primary and allied clans on the clan select and challenge creation screens.
  7. UI - by player request, show which ring 3 and ring 6 bosses you will face on the run on the run start screen.

    bosses.

Friends and Foes - Public Test Train

This second major update for Monster Train adds new champions, new bosses, new cards, and new artifacts, which combine together to add a significant amount of new strategic options and replayability. We’ve also added a number of frequently requested player features like a personal run records page in the Logbook, an enemy wave counter in battle, and a preview of the ring 3 and ring 6 bosses at the start of a run.

NOTE: for the Public Test Train, we are temporarily setting runs to always use the new bosses. When the update goes live, run generation will go back to normal and mix in the new bosses with the old. Also, all changes listed are still subject to change before the update officially launches.

You are welcome to join us for feedback and discussion on the official Monster Train Discord server in the #public-test-train channel.

  10. Stackstone now increases Ember cost by 1 in addition to adding Doublestack. This is our one big nerf for this update. Overall the data and feedback showed that this was one of the biggest ways to swing a run easily and as it was relatively easy to pull off we added this drawback to bring it a bit more in line with other upgrades. We'll be keeping an eye on the results in the public test train and beyond and buffing any cards that seem to have had an outsized impact from this change.
