MU: Pocket Knights to get major new update switching up growth and challenges

MU: Pocket Knights just dropped its second major update.

It brings a brand-new Rune system and a heap of fresh content.

That includes a special Halloween event to dive right into.

Since its launch in September, MU: Pocket Knights has been in the hands of fans for quite some time—and according to developer Webzen, the response has been largely positive. But if you’ve had any complaints about the game, this second major update might just address them.

This update introduces significant overhauls to growth systems and challenges. At the heart of it is the new Rune system. Like in other RPGs, you’ll be able to socket runes into your gear to boost your character’s stats.

Runes can be obtained through regular gameplay, and the devs aim to give you more freedom to tailor your character’s power. It’s a smart addition—one that’ll likely appeal to players sitting on underused gear that just needs a little upgrade to shine.

The runes are cast

The number of challenges has also expanded significantly—with 30 new chapters for Battles, another 30 for the Blood Castle, Square of Devil, and Maze of Dimension dungeons, and 20 for The Abyss. If you’re hunting for rewards—including runes—this is your prime opportunity.

Keep an eye out for additional new content too, like fresh equipment and costumes. Plus, there’s a Halloween event called Trick or Treat Rush, where you’ll collect Pumpkins and Halloween candies to trade for exclusive rewards.

MU: Pocket Knights still has a long way to go to match the legacy of its iconic predecessor. But if you’re curious about what other mobile games are standing out in 2025, good news—we’ve gathered the best ones so far in one place for you to explore.
