The Serpent King
Obari (Obanai)
Obari stands in a paved square with a torii, right beside the Mother Bear, so the two share a trip. Everything a Serpent user farms is on his bar: the Serpent Katana, the Serpent Haori and Slithering Serpent, the style's last move, now at 10%.
The skill tree's last Serpent node simply says Defeat Obari, which sends a lot of players looking for him.

After the patch: Serpent Haori x1 (3%), Serpent Katana x1 (5%), Slithering Serpent x1 (10%).

The torii square by the Mother Bear
A paved stone square with a low wall and a torii, north-east of Bamboo Grove and right next to the Mother Bear. The Hidden Mist shrine is a short walk south-east.
- Teleport to the Windy Peak shrine and ride east, or to the Hidden Mist shrine and walk north-west.
- Ride east up a misty path under a torii; Obari's square is just past the Mother Bear's bar.
- Zentaro stands a short ride further east, so the two chain well.

Serpent Katana, Haori and Slithering Serpent
| Item | Chance | Kills for a 90% chance |
|---|---|---|
| Serpent Haori | 3% | 76 |
| Serpent Katana | 5% | 45 |
| Slithering Serpent move scroll | 10%5% at launch | 22 |
A luck boost multiplies every line and says so: with (2x Luck) his bar has read 6%, 10% and 20%. The scroll line reads Already Have once you own the move. How the last move unlocks is on the Serpent page.
His Serpent kit
- He fights with Serpent's own moves, including the last one you are farming him for.
- His health is 3,000 alone and goes up by 1,000 for each extra player hitting him.
- Each kill costs 120 Reputation; see reputation.

The Serpent King Obari, 3000 / 3000, World Events Chest: Serpent Haori x1 (3%), Serpent Katana x1 (5%), and Slithering Serpent x1 (5%) struck with Already Have.

The ride up to Obari's square, a torii at the top of the path.
Which Obari?
- The skill tree says Defeat Obari. Which Obari?
- The boss in the square by the Mother Bear, not the Serpent trainer of the same name.
- I killed him 100 times with no katana.
- At 5%, about one player in 170 goes 100 kills without it. It is rare, but it happens. The 35-kill pity is for the scroll line.
The fight, and the ride there
