To unlock Serpent Breathing in Slayers 2, reach level 25 on the Slayer path, unlock Wall Climb, bring Obari 20 Demon Horns and 5 Beast Cores, then complete his training quest and defeat the Serpent Trainee. Obari is reported to be on a cliff above the Windy Peak starting area. One guide also lists a 1,000 Wen fee, but other recent guides omit it, so check Obari’s dialogue before farming or turning in materials.
What you need before visiting Obari
- Level: 25 or higher on the Slayer path.
- Movement skill: Wall Climb unlocked to reach the reported cliffside location.
- Materials: 20 Demon Horns and 5 Beast Cores.
- Possible fee: 1,000 Wen is listed by one recent guide, but other guides do not confirm it. Verify the cost in Obari’s dialogue.
The level and material requirements are reported by Slayers2Wiki, Roblox Den, and Slayers2.com. The extra fee appears in Pro Game Guides; AllThings.How recommends checking with the trainer because costs may vary. These are community guides rather than official game documentation, so confirm requirements in-game.
How to find Obari
Look for Obari on the cliffs above the Windy Peak starting area. Guides place him overlooking the starting village and Zuko’s spawn, with descriptions of the approach varying; one describes the climb between Windy Peak and Bamboo Grove. Use an in-game marker if one appears, and check that you have Wall Climb before setting out.

How to gather the required materials
Demon Horns
Demon Horns are reported as demon drops. A route guide points players to the cave below the Mother Bear area as a place to search for demons. Drops are not guaranteed, and no verified drop rate is established.
Beast Cores
Beast Cores are reported as drops from Beast Born Demons. One guide suggests searching near the village gate at Mistfall Harbor at night. Treat this as a suggested hunting area, not a guaranteed spawn or drop schedule.
Rank #2
- Punch demons with the power of bands created!
- The battle of Tanjiro Kamado will again unfold …
Both the 20 Demon Horns and 5 Beast Cores are repeated requirements in the recent Slayers2.com, Slayers2Wiki, and Roblox Den guides.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Does Serpent Breathing cost 1,000 Wen?
That cost is unresolved. Pro Game Guides lists 1,000 Wen in addition to the materials, while other recent guides give the material requirements without that fee. Neither an official game source nor direct in-game confirmation is established by these references. Check Obari’s dialogue in your current version rather than assuming the fee is required or absent.
