Weak Legacy 2 continues to dominate the Roblox anime scene, drawing Demon Slayer fans into a world where mastering your Breathing Style determines your strength. If your goal is to fight with the venomous precision and coiling strikes of the Serpent Hashira, Obanai Iguro, then Serpent Breathing is the perfect choice.

Step 1: Meet the Requirements

Before you can begin your training, you’ll need to make sure your character meets a few key conditions. Serpent Breathing is exclusive to Human Demon Slayers, so if you’ve been playing as a Demon, you’ll need to reset your race first.

1. Race:

  • Required: Human (Demon Slayer)
  • Note: Demons are unable to learn any Breathing Styles, so make sure your character is part of the Demon Slayer race before proceeding.

2. Stat Recommendation:

  • Recommended: High Strength
  • Note: While not strictly required, Serpent Breathing’s attacks scale effectively with Strength, giving you higher damage output and smoother combos.

3. Yen/Cash:

  • Needed for: Purchasing skill forms
  • Note: You’ll need a large amount of Yen to unlock all five Serpent Breathing forms. Focus on grinding through quests and boss battles to earn enough currency.

Step 2: Locate the Serpent Trainer

Finding the Serpent Trainer can be tricky if you don’t know where to look. The NPC, modeled after Obanai Iguro, usually resides in one of the game’s remote mountain areas.

  • Trainer Name: Based on Obanai Iguro
  • Location: Typically found in the Mountainous Village or Snow Village
  • Exact Spot: Look for a high, isolated cliff or ledge, often near winding paths or an old shrine—areas that give off a “snake’s nest” aesthetic

Travel Tip:

Start from the main hub area and move toward the Snow/Mist/Thunder Trainer zones. Then, climb higher up the mountain away from the main village to find the Serpent Trainer’s hidden spot.

Step 3: Complete the Serpent Trainer’s Quest

Once you’ve reached the Serpent Trainer, speak to them to begin your trial. You’ll need to prove your worth before learning Serpent Breathing.

  1. Talk to the Trainer: Interact and select “Yes” when asked to start the challenge.
  2. The Challenge: Defeat 3–5 Demons located near the base of the mountain or within a nearby cave.
  3. Return Victorious: After finishing the task, return to the trainer to receive your reward—access to Serpent Breathing!

Quick Note: This quest is designed to test your combat endurance and precision—traits essential for mastering Obanai’s style.

Step 4: Purchase and Master Your Forms

Once you’ve unlocked Serpent Breathing, the real fun begins. Use Yen to buy each of the five unique forms and unleash your inner Hashira.

Here are some key Serpent Breathing moves to focus on:

  • Winding Serpent Slash – A fast, sweeping attack with strong AoE potential.
  • Venom Fangs of the Narrow-Head – High damage, venom-infused strikes.
  • Coil Chop – A powerful charged slash that holds enemies in place.
  • Slithering Serpent – The ultimate form, dealing devastating area damage.

Each form combines speed, precision, and flexibility—making Serpent Breathing an A-tier style for both PvE and PvP gameplay.

Why Choose Serpent Breathing?

Serpent Breathing stands out for its fluid combos, wide AoE attacks, and unique visual flair inspired by Obanai Iguro himself. It’s perfect for players who enjoy aggressive, mobile combat styles with a balance of offense and defense.
