Team Composition & Strategy Tips
- The buff duration reduction removing Stun Immunity is troublesome
- Draw single-target attacks with Li
- Use Orchestrator to increase his Effect Resistance for Stun Immunity - Reduce Li's cooldowns with Velika
- It's recommended to have Velika with the highest Speed and Li with the lowest - Alternate between Physical and Magic attacks
- Physical Resistance and Magic Resistance will switch - A complete shutdown is possible with 201 or more Speed
- You can push through with a Physical team, but it involves some luck
Stun Immunity is removed by Buff Duration Reduction
Kohkun will inflict Stun, but even if you include heroes with Stun Immunity, it will be removed by the additional rule that reduces buff duration on a Basic Attack. Because of this, it's a tricky point that even if you use Evan or Sieg, they can still get Stunned.
Draw Single-Target Attacks with Li
As a countermeasure to the aforementioned Stun Immunity removal and to prevent your attackers from being defeated by Rahkun's high-damage Basic Attacks, it's recommended to draw attacks with Li's Taunt and Physical Attack Reduction, after equipping him with Orchestrator gear to get his Effect Resistance to 100%.
 Tips! | Since Li will take almost all of the attacks, you won't need to include a Stun Immunity hero. You can use Ryan, but Li is more stable due to his shorter Taunt skill cooldown. |
|---|
Reduce Li's Cooldown with Velika
To ensure Li's Taunt skill is always active, use Velika as a cooldown reduction unit and make her the fastest in the party. By making Li the slowest in the party, you can reliably maintain his Taunt without any gaps.
Alternate Between Physical and Magic Attacks
When Rahkun uses Skill 1, he gains Magic Resistance, and when he uses Skill 2, he gains Physical Resistance. It's recommended to attack with the wide-range Physical attacker Kyle and the magic attacker Sun Wukong depending on the situation.
Physical Attacks Are Effective for a Longer Time
Due to the enemy's skill cooldowns, Physical attacks are effective for a slightly longer period, so it's also a valid strategy to attack with a 3-Attacker formation using heroes like Lu Bu or Fai instead of Sun Wukong.
| Tips! | Note that due to the Debuff Immunity rule, Lu Bu's Defense Reduction and Fai's Burn will not work. |
|---|
A Complete Shutdown Is Possible with 201+ Speed
If you have 201 or more Speed, you can go first to apply Physical Attack Reduction & Taunt, aiming for a complete shutdown. Additionally, since the boss Rahkun gets weaker each time you defeat a Kohkun, you can clear safely even if your Taunt wears off.
You Can Push Through with a Physical Team, but It Involves Luck
Sieg
Lina
Lu BuIt is possible to push through with the firepower of a Physical party like the one above. However, if your Stun Immunity is removed or your attackers are defeated, you may have to restart, so there is an element of luck involved in who gets attacked.
Best Team & Pets
Basic Party Example
| Front Row | Front Row | Front Row | Back Row | Back Row |
|---|---|---|---|---|
 Biscuit |  Velika |  Li |  Sun Wukong |  Kyle |
This is a party example where Li draws Basic Attacks and Stun with his Taunt, Velika reduces cooldowns, Biscuit provides buffs/debuffs, and Sun Wukong and Kyle attack. When Rahkun uses Skill 1, attack with Kyle. When he uses Skill 2, attack with Sun Wukong.
Roles and Recommended Equipment Here
Li-centered Physical Party Example
FaiThis is a party example that takes advantage of the longer uptime of Physical attacks by using a 3-Attacker formation. If you don't have Fai, you can use other Attack heroes like Shane, Kagura, or Branze & Bransel.
Roles and Recommended Equipment Here
Recommended Pets
| Recommended | Alternative (Legendary) | Alternative (Rare) |
|---|---|---|
 Windy |  Yu |  Little Feng |
Since all enemies are bosses, the most recommended pet is Windy. If you don't have Windy or it's not raised, Yu is a candidate as he can counter Life Drain and reduce Defense.
Featuring 6-Medal Party Examples
The above are party examples for aiming for 6 medals. If you reduce the number of medals, the lack of buff duration reduction on Basic Attacks broadens your team composition options, such as including Stun Immunity.
