By: Osama
Updated On: October 5, 2025

To become a demon in Weak Legacy 2, head to the snowy area right of Starter Village and speak to the demon transformation NPC (Douma/Muzan) for 1,000 Yen. This permanent transformation unlocks powerful Blood Demon Arts but removes your humanity. Demons use BDAs instead of Breathing Styles, gaining unique dark abilities that make you formidable against Demon Slayers.

This comprehensive guide will walk you through every aspect of demon life in Weak Legacy 2, from finding the elusive transformation NPC to mastering the most powerful Blood Demon Arts. Whether you're seeking raw power or want to experience the game from the demon perspective, we've got you covered with verified information from multiple sources and expert strategies.

How to Become a Demon in Weak Legacy 2

Finding the Demon Transformation NPC

The journey to demonhood begins in the snowy biome, located to the far right of the Starter Village. This area is easily identifiable by its white landscape and distinct architecture. The demon transformation NPC can be found among the Blood Demon Art trainers, though there's some variation in reported names across different sources:

  • Most sources refer to the NPC as Douma, located in a secret cave behind trees and houses in Snow Village
  • Some players report the name as Muzan, positioned as the last NPC in the row of Blood Demon Art trainers
  • Occasionally referenced as Muzzan in older guides

This naming discrepancy likely stems from game updates or regional variations, but rest assured that whichever name appears, this NPC offers the same demon transformation service.

Transformation Requirements

To become a demon, you'll need to meet two simple but significant requirements:

  1. 1,000 Yen: The in-game currency required for the transformation
  2. Your Humanity: This is a permanent change - you'll lose your human status and all associated abilities

The process is straightforward once you've located the NPC:

  1. Approach the demon transformation NPC in the snowy area
  2. Interact with them to receive the transformation offer
  3. Accept the offer and pay the 1,000 Yen fee
  4. Confirm your decision to permanently become a demon

Important Note: This transformation is irreversible through normal means. While you can reset back to human later, it requires either spending Robux or obtaining a rare Race Reset Ticket from game codes.

What Changes When You Become a Demon?

Transforming into a demon fundamentally alters your gameplay experience in Weak Legacy 2:

Losses:

  • Human Breathing Styles become unavailable
  • Alignment with Demon Slayer Corps is severed
  • Access to human-specific quests and NPCs may be limited

Gains:

  • Access to Blood Demon Arts (BDAs)
  • Demon-specific abilities and perks
  • New questlines and interactions
  • Enhanced combat capabilities against Demon Slayers
  • Access to Demon Regeneration (at higher levels)

The trade-off is significant but worthwhile for players seeking a different playstyle or those who prefer the dark, destructive nature of demonic powers.

How to Learn Blood Demon Arts?

  1. Reach the required level (typically Level 5 for most BDAs)
  2. Earn sufficient Yen (costs vary by BDA, usually 1,000 Yen)
  3. Complete specific tasks (often involves defeating Demon Slayers)
  4. Locate the appropriate trainer in Snow Village
  5. Interact with the trainer and meet their requirements
  6. Learn the Blood Demon Art and practice its abilities

Pro Tip: Some Blood Demon Arts have multiple forms or abilities that can be unlocked progressively. Always check if there are additional requirements for mastering your chosen BDA completely.

Advanced Demon Features & Mechanics

Demon Regeneration

One of the most powerful abilities available to high-level demons is Demon Regeneration. This exclusive perk allows you to recover health during combat, significantly increasing your survivability.

Requirements for Demon Regeneration:

  • Level: 200
  • Cost: 50,000 Yen
  • Cooldown: 60 seconds
  • Location: Same area as other BDA trainers in Snow Village

Strategy: Demon Regeneration is a game-changer for both PvE and PvP content. The high cost and level requirement make it an end-game goal, but the investment is well worth it for serious demon players.

Race Reset: Returning to Humanity

If you decide that demon life isn't for you, or if you want to experience both sides of the conflict, you can reset your race back to human.

Reset Process:

  1. Locate the Reset Race NPC in Little Village
  2. Choose your reset method:
    • Pay 120 Robux (premium currency)
    • Use a free Race Reset Ticket (obtained from game codes)

Important Considerations:

  • The 1,000 Yen paid to become a demon is not refunded
  • All Blood Demon Art progress is lost
  • You'll need to restart your journey if you want to become a demon again

Finding Little Village: From the Starter Village, follow the road to the left until you reach Little Village. The Reset Race NPC is easily identifiable by their distinct icon.

Frequently Asked Questions

How do I find the demon transformation NPC?

What's the exact cost to become a demon?

Becoming a demon costs 1,000 Yen plus your humanity. The Yen cost is straightforward, but remember that giving up your humanity is a permanent change that can only be reversed by paying 120 Robux or using a Race Reset Ticket.

Can I switch between human and demon freely?

No, race changes are not free. You can reset from demon back to human by visiting the Reset Race NPC in Little Village and paying 120 Robux or using a Race Reset Ticket. There's no cost to switch from human to demon beyond the initial 1,000 Yen.

What's the best Blood Demon Art for beginners?

For beginners, Dark Thunder is often recommended due to its straightforward mechanics and high damage output. Emotion Manifestation is also excellent for its versatility, though it may have a higher skill ceiling.

How do I get Demon Regeneration?

Demon Regeneration becomes available at Level 200 and costs 50,000 Yen. You can learn it from the Demon Regeneration trainer in the same area as the Blood Demon Art trainers in Snow Village. It has a 60-second cooldown.

Are there any exclusive demon quests or content?

Yes, demons have access to specific quests and content not available to humans. These often involve defeating Demon Slayers, learning specific Blood Demon Arts, and participating in demon-focused community events.

What happens to my progress if I reset back to human?

When you reset back to human, you lose all demon-specific abilities including Blood Demon Arts and Demon Regeneration. However, you retain your general level, Yen, and items. You'll need to restart the demon transformation process if you want to become a demon again.

How often do Blood Demon Arts get balanced or updated?

Blood Demon Arts receive balance updates with major game patches, typically every few months. The developers are active in the community and often adjust BDA effectiveness based on player feedback and meta changes.

Can I be both a demon and use Breathing Styles?

Is it better to play as a demon or human in Weak Legacy 2?
