Mobile Legends Patch 2.1.66 Update: New Hero
New hero: Hirara
A geisha ninja from the Scarlet Shadow, she defies all odds to return, wielding the legendary Twin Fans: Ukifune. She dances across the battlefield with grace, reaping with her elegant yet lethal twin fan combos. Every strike is a tribute to ultimate protection for the master she serves – Hanabi.
Hirara is an Assassin wielding Twin Fans: Ukifune, capable of combining them to unleash different combos.

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 wields Kaerazu, scattering maple leaves that deal damage to enemies in a fan-shaped area. After a short delay, the leaves ignite, dealing higher damage.
Skill 2: Mesisen-e
Hirara wields Meisen-e and treads upon the meisen to dash once in the targeted direction and once in the joystick direction.
Skill 1 & 2 Combo: Infernal Torrent
You can combines the power of Kaerazu and Meisen-e to summon Crimson flames. You can dash in the joystick direction and deals AOE damage in a circular area, followed by another instance of higher damage after a short delay.
Skill 2 & 1 Combo – Falling Maple
You can combine the power of Meisen-e and Kaerazu to plunge into the meisen, becoming untargetable and immobile. After a short delay, you can dash twice in the joystick direction.
Ultimate – Forbidden Jutsu: Momijigari
You’ll unleash the power of the Twin Fans: Ukifune, donning a dress interwoven with crimson and death. This increases the maximum capacity of her passive Crimson/Death Energy to 6, setting the stage for a spectacular battle.

Battlefield Adjustment
New Battlefield Effects
New battlefield effects are back on the Advanced Server. The Devs has made some optimizations based on feedback from the last test and added a new effect. The art performance for this gameplay is still under test and isn’t the final quality . The Devs will make the relevant gameplay available at a later time after this week’s patch update.
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.
