Why Become a Demon in Slayer 2?
Choosing the Demon race in Slayer 2 completely changes your playstyle. Instead of learning breathing styles from human trainers, demons draw power from Blood Demon Arts (BDAs) obtained from Muzan and demon-related NPCs. The trade-off is real — sunlight, hunger, and the loss of your sword-based kit — but the payoff is one of the strongest early-game power spikes available.
Blood Demon Arts
- Replaces breathing styles entirely
- Ranged string, arrow, and shockwave skills
- Learned from Muzan and demon NPCs
Passive Regeneration
- Health regenerates over time
- Sustained farming without heal items
- Strong in extended PVP fights
Sunlight Weakness
- Burns during daytime exposure
- Must manage movement and timing
- Requires map-awareness discipline
The current community tier list places the Demon Race in S-tier, noting that "Blood Demon Arts plus demon passive regeneration give strong early and mid-game power," while Slayers scale better late game with weapon upgrades and breathing mastery.
Once you become a Demon, your breathing style progression is replaced by Blood Demon Arts. Switching back to the Slayer path later requires significant investment — weigh your decision before accepting Muzan's blood.
Step-by-Step: How to Become a Demon
The transformation follows a consistent path: progress as a human, locate Muzan's spawn, survive the encounter, and accept his blood. Follow these steps in order.
Reach the Required Level First
Don't rush the demon path at level one. Farm low-level bandits and demons near the starting village (Kiribating), and always accept quest NPCs before grinding — quest rewards stack on top of kill XP for the fastest early leveling.
Stock Up on Supplies
Bring healing items and enough currency (Wen). The Muzan encounter is a boss-level threat, and under-leveled players who fight bosses early are one of the most common beginner mistakes in Slayer 2.
Locate Muzan's Spawn
Muzan spawns in demon-affiliated territory — typically the high-level Demon Territory/Swamp region of the map. This zone is dangerous, so unlock fast travel points and prepare an escape route before heading in.
Survive the Encounter
Depending on the current build, Muzan either tests you in combat or offers a dialogue choice. Bring friends or higher-level players for your first attempt — world bosses in this game are not tuned for solo under-leveled clears.
Accept Muzan's Blood
Accept the transformation to officially switch to the Demon race. Your breathing style access is replaced by Blood Demon Arts, and demon mechanics — regeneration, sunlight weakness, hunger — activate immediately.
Demons burn in sunlight, so plan your farming routes around indoor zones, caves, and night-time cycles. Indoor boss areas like dungeon entrances let you farm safely regardless of the day cycle.
Blood Demon Arts Comparison
Your Blood Demon Art defines your demon build. Each BDA is obtained from Muzan or demon trainer NPCs and offers a distinct combat identity. Here is how the confirmed arts compare:
| Blood Demon Art | Tier | Playstyle | Best For |
|---|---|---|---|
| String BDA | S | Close-range pressure, multi-hit threads | PVP combos, boss damage |
| Temari Ball BDA | A | Ranged bouncing projectiles | Spacing, keep-away PVP |
| Shockwave BDA | B | Ground slams, knockback bursts | Mob farming, disrupting combos |
| Arrow BDA | B+ | Directional and tracking arrows | Ranged poke, punishing disengages |
Recommended Stat Builds by Art
| Art | Priority Stats | Reason |
|---|---|---|
| String BDA | Attack, Health | Aggressive close-range pressure rewards bulk |
| Arrow BDA | Attack, Stamina | Constant arrow pressure needs stamina sustain |
| Shockwave BDA | Health, Attack | Brawler playstyle benefits from tankiness |
| Temari Ball BDA | Stamina, Attack | Sustained ranged volleys drain stamina fast |
The String BDA sits in S-tier for good reason: high sustained damage and reliable combo starters dominate both PVP and boss fights. If you get a choice, start there.
Demon vs. Slayer: Which Path Is Better?
Neither path is strictly superior — they peak at different stages of progression. Here's the honest breakdown:
| Factor | Demon Race | Slayer Race |
|---|---|---|
| Early game | Strong spike (BDA damage, regen) | Slower start |
| Late game | Plateaus somewhat | Scales with weapon upgrades |
| Sustain | Passive health regeneration | Relies on healing items |
| PVP | Strong combo arts (String BDA) | Mobility from breathing dashes (Thunder) |
| Restrictions | Sunlight, hunger mechanics | Fewer restrictions, trainer quests |
| Skill source | Muzan / demon NPCs | Breathing trainers across the map |
The current tier list ranks Demon Race in S-tier for raw accessibility and Slayer Race in A-tier, noting Slayers "scale exceptionally well late game with breathing mastery and weapon upgrades." Pick Demon for immediate power, Slayer for long-term scaling.
Demon Progression Checklist
Once you've transformed, work through these milestones to turn your demon into a boss-clearing machine.
Demon Path Milestones:
- Survive the Muzan encounter and accept his blood
- Unlock your first Blood Demon Art from a demon trainer
- Invest stat points per your BDA's recommended build
- Learn sunlight-safe farming routes (caves, dungeons, night cycle)
- Farm world bosses in the Demon Territory for rare moves
- Clear timed dungeons with a party for exclusive rewards
Exhausted players cannot block, dash, or use skills. Temari and Arrow builds especially need stamina discipline — running dry mid-fight against a Thunder Breathing Slayer is a guaranteed loss.
FAQ

Q: Which Blood Demon Art is the best?
The String BDA currently sits in S-tier thanks to high sustained damage and reliable combo starters in both PVP and boss fights. Temari Ball is the top pick for players who prefer ranged spacing instead.
