The Dark Thunder fighting style is one of the most powerful and visually striking abilities in Weak Legacy 2, offering players lightning-based attacks with devastating effects. This guide explains everything you need to know to unlock Dark Thunder V1 and upgrade it to V2, including the full requirements, locations, and farming tips.


How to Get Dark Thunder V1

Before starting, make sure you meet the basic requirements:

  • Level Required: 15 or higher
  • Yen Needed: 10,000

Once ready, follow these steps:

  1. Travel to Winter Village. Head straight toward the Winter Village area. This snowy zone is where you’ll find the key NPC.
  2. Find Kaigakus (Dark Thunder Trainer). Kaigakus can be found slightly off to the side in Winter Village. Once you spot him, interact with him to start the Dark Thunder V1 quest.
  3. Defeat 25 Demon Slayers. Kaigakus will ask you to defeat 25 Demon Slayers before he can teach you the style. These enemies spawn frequently in open areas between the main villages, making them fairly easy to find.
  4. Return to Kaigakus. After completing the kills, go back to Kaigakus and talk to him again. He will then teach you Dark Thunder V1, officially unlocking the first version of the style.

How to Unlock Dark Thunder V2

Once you’ve mastered the first version, you can upgrade to Dark Thunder V2, but the requirements are much higher.

Dark Thunder V2 Requirements:

  • Level 400
  • 1,000,000 Yen
  • 200 Mastery
  • 20 Lightning Orbs
  • 1 Crystal Essence

After meeting all of the above conditions, return to Kaigakus in Winter Village. He’ll recognize your progress and upgrade your Dark Thunder to V2, unlocking a more powerful move set and faster lightning attacks.


Tips for Faster Farming

  • Farm Demon Slayers in groups. You’ll clear enemies faster and get kill credit even if someone else finishes them off.
  • Use Luck Boosts and Stat Buffs to grind lightning orbs efficiently.
  • Focus on Mastery Early. You’ll need 200 mastery later, so start building it up right after getting V1.
  • Keep Yen saved. Between both versions, you’ll spend over 1,010,000 yen, so plan your farming runs accordingly.

Dark Thunder V1 and V2 are some of the best fighting styles in Weak Legacy 2, especially for players who love high-speed combat and flashy visual effects. While the requirements for V2 might seem steep, the upgraded damage, range, and overall combat flow make it one of the most satisfying styles to use in-game. If you’re looking to dominate fights and show off a truly electrifying style, unlocking Dark Thunder V2 is absolutely worth the grind.
