Hello, this is the MonMon Masters development team.
We would like to express our deepest gratitude to all the Masters who have always shown MonMon Masters such warm interest and love. In this v1.6.8 update, alongside the highly customizable new 'Costume System,' the update's core main content — the 'Astro Defenders Large-Scale Collab Event' — comes to visit you! 6 new MonMon, including ones inspired by Astro Defenders, join the roster together, unfolding an even richer adventure.

We've thoroughly refined the overall structure so that progressing through the Field feels smoother.
Early Experience Improvements
We've reworked the early-game flow so that Masters starting MonMon Masters for the first time can settle in more comfortably.
Convenience Improvements
Combat System & Balance Adjustments
Combat System Adjustment
For some MonMon skills that target based on lowest HP, the targeting criteria is changed from "HP percentage" to "absolute HP value."
Reward Adjustment
Deco Coins have been added to the Tamers League weekly rewards.
The new currency, Deco Coin, is added as a guaranteed item in the weekly rewards for every tier. Existing rewards remain unchanged, and the amount below is granted in addition.

Bug Fixes & Optimization
Official Discord Announcement
The MonMon Masters development team avoids chasing short-term results or one-off operations. Above all else, we believe the most important thing is ensuring that our Masters' precious time and love are never wasted — by building a "sustainable game" and a "MonMon Masters that players can trust and enjoy for the long haul."
The Official Discord is more than just a channel for announcements — we plan to build it into a comfortable space where the development team directly listens to and responds to the voices of our Masters. Special events and rewards exclusively for our Discord Masters will also be prepared on a regular basis.
Every piece of honest feedback our Masters leave behind is a precious foundation that helps us build a better game. We sincerely ask that you join us on the long journey ahead for MonMon Masters.

Thank you. — MonMon Masters Development Team
