Aniimo Binding Oath Walkthrough: All 3 Vine Core Locations

Binding Oath is a Journey quest in Aniimo that starts in The Mistwoods, one of the areas inside the Breezy Plains region. After a talking Hummin pulls you underground, the quest splits into a three-part search for Vine Cores scattered across opposite corners of the map. Two of the three are locked behind Aniimo abilities rather than combat, so a little prep saves a lot of backtracking.

Quick answer: Visit the eastern ruins, western swamp, and northern cave in The Mistwoods to pick up the three Vine Cores. Deliver them to Ron at Twisted Roots, talk to him once more, and then meet Selens aboveground to finish the quest.

How to unlock Binding Oath

Binding Oath becomes available after you beat the boss Tucking during the Ancient Sacred Fragrance main quest. When you defeat Tucking while hunting the Super Truffle in The Mistwoods, a new hole opens in the ground nearby. It is easy to miss, so check the area behind you once the fight ends.

Use the map to select Binding Oath, then follow its marker to the central pit in The Mistwoods. The current objective says “A talking Hummin?”

Jump down into the pit, which leads to the Twisted Roots underground zone. This starts the “A Century-Old Promise” cutscene, where the odd Hummin is revealed as a boy called Ron. He says three vines in the area are withering and sends you to collect their three Vine Cores. Their locations are marked on your map immediately.

Before climbing back out, unlock the Twisted Roots fast travel point. You must return here with the cores, and teleporting avoids repeating the full ascent.

What to bring before collecting the Vine Cores

Two of the cores require Aniimo abilities, so arrange your battle party before setting out. Wild Aniimo between levels 36 and 46 roam the route; bring Aniipods for both catching and battling them.

Use a Fire Aniimo, such as Flameruff, to remove the brambles covering the northern cave.
An Electric Aniimo such as Bolty to light the plants inside that cave.
Choose a Twining that can climb or glide to reach the ruin walls and the cliffs over the swamp.
Aniipods for the wild Aniimo patrolling the paths.

The Mistwoods contains two environmental details to keep in mind. Interacting with Glimmer Trees illuminates the route, while moving directly through swamp pools leaves you severely slowed; glide or hop across them instead.

All 3 Vine Core locations

You may take the three cores in any sequence, though going east, west, and then north creates a straightforward circuit. Each location has a glowing vine flower activated with the F Touch prompt, followed by a brief cutscene. Every flower also has a chest beside it, so collect each chest’s loot before continuing.

Vine Core	Location	What it needs
Eastern ruins	Chamber under the ruin roof	Wall climb, roof entry
Western swamp	Hill in the misty swamp	Glide from the cliffs
Northern cave	Deep inside the cavern	Fire and Electric Aniimo

Eastern ruins Vine Core

Follow the eastern marker to the ruins. Near the stone steps at the entrance, wild Aniimo are gathered, including a level 36 Hexxin available to catch as you go by.

Do not walk into the lower ruin chamber at ground level. A singing Hexxin in there knocks you out on contact and respawns you outside the ruins.

Use the outside stonework to gain height. Circle the building until you arrive at the roof opening over the chamber.

Enter via the roof and make contact with the glowing flower underneath. This triggers the “Magic Sound Duet” cutscene, adds the eastern ruins Vine Core to your inventory, and immediately unlocks a chest in that chamber.

Western swamp Vine Core

From the ruins, go west for the next marker. You first gain altitude and then descend, ending up on tall cliffs above the mist.

Glide off the cliffs into the swamp instead of going down by foot. You will land close to the marker while bypassing most contaminated pools. If you stay on the ground, use the vines and raised platforms to cross rather than walking through the water.

On the little hill protruding from the swamp, interact with the glowing flower. “Dream of a Lifetime” then plays; the western swamp Vine Core is obtained, and a second chest is close by.

Northern cave Vine Core

Head northeast through the forest and rocks toward the final marker. The cave entrance is sealed by a thick bramble wall that normal attacks cannot break.

In Aniimo Management, add a Fire Aniimo to your battle party unless one is already present. Flameruff is suitable.

Call out the Fire Aniimo and have it burn away the brambles, then enter. Immediately beyond the entrance, the Mysterious Pathfinder leaves the message “What you need is Light.”

Change to an Electric Aniimo, such as Bolty. Its electricity activates the wall plants that respond to light, exposing the route farther into the darkness.

Stay on the illuminated path until you reach the glowing vine flower, then interact with it. The “Mistlight and Starlight” cutscene begins, the northern cave Vine Core is added, and a chest is positioned immediately behind the flower.

The cave continues past this point. Deeper tunnels hide extra chests, a Lumin Amber: Breezy pickup in the ruins section, and a level 46 Wisptis you can fight and catch. None of it is required for Binding Oath, so skip it if you only want the quest done.

Hand in the cores and finish with Selens

Bring up the map and warp to the Twisted Roots waypoint. Approach Ron and approve delivery of all 3 Vine Cores; this triggers “The Inheritor of the Vow.”

Once the scene is over, talk to Ron a second time. He discloses that Selens is his true name, and the next objective directs you to Selens on the surface.

Warp to the Mistwoods surface waypoint and speak with Selens, who is there alongside Tucker. “The Real Promise” plays, completing Binding Oath.

There is no need to open the log to confirm completion. The rewards appear as soon as the last scene finishes, and Dr. Lewis sends an incoming communication request for the follow-up mission. The Rigged Maze Sanctum is on this same part of The Mistwoods and contains an optional chest; visiting it is a worthwhile detour, but it is unrelated to quest completion.

Sparkling Crystal is a crafting material for Sparkling Cubes, and Tesella Pod in Astra purchases it wherever it appears. Binding Oath is an Epic mission item, not currency. Selens created it from Glimmer Fruit; the perfume, also known as the Beautiful Voice Perfume, gives its user a lovely singing voice. Its flavor text describes the twined pair becoming each other’s greatest friend and making an eternal, binding oath.
