The newest update to Mobile Legends: Bang Bang (MLBB), Patch 2.1.66, is now available on the Advanced Server. This update introduces a new Assassin hero and includes adjustments to hero balance, equipment, and overall gameplay. Developers have also tweaked mana costs for Marksmen heroes in the Gold Lane, aiming to improve their performance and how players control them. Here’s a detailed look at what’s new in Patch 2.1.66.

Mobile Legends Patch 2.1.66 Update: New Hero

New hero: Hirara

Hailing from the Scarlet Shadow, this skilled warrior is a geisha ninja who overcomes every challenge to return to the fight. She wields the famed Twin Fans: Ukifune, moving with beautiful precision and delivering deadly, flowing attacks. Each strike is a demonstration of her unwavering loyalty and dedication to protecting her master, Hanabi.

Hirara is an Assassin who fights with a pair of fans called Ukifune. She can combine them in various ways to perform different attack combinations.

Passive– Twin Fans: Ukifune

  • Twin Fans: Ukifune consists of two weapons Kaerazu and Meisen-e. Skill 1 and 2 represent the abilities of these two weapons respectively.
  • You can cast the skills individually or combine them just by dragging.
  • Hirara has 4 stacks of Crimson/Death Energy. Casting a single skill costs 1 stack of Energy, while casting a combo skill costs 2 stacks.
  • Skills cast by Kaerazu and Meisen-e can apply Crimson and Death marks to enemies. Enemies hit by both marks simultaneously will be briefly immobilized.

Skill 1: Kaerazu

Hirara uses her weapon, Kaerazu, to send out a flurry of maple leaves that hurt enemies in a wide, fan-like area. A moment later, these leaves burst into flames, causing even more damage.

Skill 2: Mesisen-e

Hirara uses her special technique, Meisen-e, to quickly move in two directions: towards her target and then in the direction the player is controlling her.

Skill 1 & 2 Combo: Infernal Torrent

As a fan, I’m really excited about this! You can combine Kaerazu and Meisen-e to create some seriously cool crimson flames. What’s awesome is you can dash in any direction using the joystick, hitting enemies all around you in a wide area. And it doesn’t stop there – a little bit later, you unleash another, even more powerful attack! It’s a fantastic combo for dealing big damage to multiple enemies.

Skill 2 & 1 Combo – Falling Maple

By using both Meisen-e and Kaerazu, you can enter a state called ‘meisen’. While in this state, you become impossible to target but can’t move. After a brief pause, you’ll be able to dash forward twice in the direction you’re holding on the joystick.

Ultimate – Forbidden Jutsu: Momijigari

Equip the Ukifune Twin Fans and outfit your character in a dress of crimson and death. This boosts her Crimson/Death Energy capacity to 6, preparing you for an incredible fight.

Equipment Adjustment

Battlefield Adjustment

New Battlefield Effects

The Advanced Server now features updated battlefield effects. Developers have improved them based on previous feedback and also added a brand new effect. While the visual quality is still being refined, they plan to release the finalized gameplay in an update later this week.

The Battlefield Effects tested in this patch are as follows:

  • Nowhere to Hide: Pickable Crystals are available across the map. Upon picking one up, its energy circles around the hero for several seconds. If there are hidden enemy heroes within a large range, the energy will move to their location and grant vision of the area for several seconds. Optimized Crystal locations, making it easier for roaming heroes to pick up.
  • Fire Turtle: Defeating the Turtle no longer grants a shield. Instead, an allied Turtle will spawn on the enemy’s weakest lane to help push it. Allied heroes near the allied Turtle will recover HP rapidly. Reduced allied Turtle’s HP but increased its HP Regen, making fights around the Turtle more competitive for both sides.
  • New Effect – Golden Turret: Greatly increased the Gold shared to the entire team when any Turret is destroyed. Inner Turret and Base Turret HP are also increased. Increased the Gold granted by each Turret to every hero by 80. Increased Inner Turret and Base Turret HP by 1000.

System Adjustment

The Auction House is available for testing on the Advanced Server. You can now list items for sale, browse what’s available, and make purchases just like normal.
