Oninoshima Mythic Challenge Quest Walkthrough: All Stages & Best Routes

Stage 1: The Serpent's Maw (First Contact)

Land at Rumble Ruins (the giant skeleton in the northwest). You need three things: break 10 cracked vases (glowing blue), open the central chest under the ribcage, and then "Honor the Ancestors" by emoting at the statue near the waterfall.

The vases are everywhere; just slide through the courtyard with a pickaxe. The chest is a guaranteed Mythic spawn, so grab it fast. Emote at the statue (it's behind the waterfall) and you're done.

Stage 2: Spirit-Tamer Trials

Now you have to tame a wild boar (found in the bamboo forest east of Rumble Ruins), then ride it through 3 fire rings near the volcano at Magma's Maw. Boars spawn near the river—whistle (emote wheel) to mount it.

The rings are floating above the lava pools. Don't jump off or you'll take burn damage. Pro tip: build a single ramp on the boar to hit the rings faster; the game counts riding *through* the ring, not staying on. The boar will dismount after the third ring, so don't waste heals.

Stage 3: The Oni's Wrath

Final stage: eliminate 5 shadow-clone enemies (they look like NPCs with purple glow) at Tengu's Peak. They spawn in waves on the mountain's eastern ridge. Use a suppressed SMG—they have low health but high damage output.

After the fifth kill, a rift spawns. Jump in to get the Mythic Oni Mask (grants double-jump and a phase-dash). This mask is the season's best mobility item, period.

Best Drop Route

Land at Rumble Ruins (Stage 1) → rotate southeast to the bamboo forest (Stage 2 boar) → head east to Magma's Maw for the fire rings → rotate north to Tengu's Peak (Stage 3). Total time: about 6 minutes if you don't get third-partied. Avoid the middle of the map—too crowded with sweat squads.

Speedrun Tips for XP Farming

If you're grinding battle pass levels, here's how to optimize:

1. Skip the boar riding — you can complete Stage 2 by shooting the fire rings with explosive rounds instead of riding through them. RPG or grenade launcher works.

2. Land directly on Rumble Ruins chest — the guaranteed mythic spawn is always in the central chest under the ribcage. Memorize the exact spot.

3. Use the Oni Mask from a previous run — if you already have it, Stages 1-2 become trivial since you can phase-dash past enemies.

4. Run it in Team Rumble — respawn enabled, less third-partying, same quest progress.

The quest chain resets every Tuesday at 9 AM ET. Rewards rotate weekly: the first week gave the Oni Mask, second week added the Spirit Flute (heals squad within 20m), and week 3 introduced the Dragon's Breath sniper variant.
