Vakron Sky Island guide
Vakron Sky Island has 3 bosses (Tiere, Vakron and Thamon). The game's own guide warns about 6 of their attacks during the Exploration run; the boss cards below quote each warning with the skill, its cast time and what it does. Vakron goes into Frenzy after 5:00 of combat. The walkthrough lists the guide's 23 route steps in order.

Rules that apply outside the boss fights, as players describe them.
Wait for the whole party
Do not hit a boss before everyone has arrived: late players are locked out of the arena and get little or no contribution for the reward. If you pulled early by accident, let the boss kill you and revive back in. [7]
Windstream glides are tight
Players report missing the updraft glides often. Let others go first to avoid collision, and expect the timing to feel strict. [7]
Players disagree: Players disagree whether to hold forward when opening the wings; some say holding it keeps you level, others say it dives you into the ledge.

Players' notes
Kill the flower, stand in its zone
~75% HPWhen she jumps to the centre, everyone gathers, kills the flower and stands inside the purple antidote zone it leaves. That zone clears the poison debuff. [1][2][4][5]
Players disagree: One written guide puts the poison phase at ~50% HP; the cheat sheet says ~75%. Players agree on how to handle it, not on the exact number.
Rotate clockwise together
~75% HPAfter the flower, the whole group moves clockwise as one clump so the purple pools drop in one spot and leave free floor. Move with the dodge button: it ignores party collision. [1][2][4][5]
Players disagree: Counter-clockwise also works if the party agrees; pugs default to clockwise.
Dodge into the slam spot
dpsWhen she slams, dodge into the spot she just left: it never holds poison. [2]
Leap and dash
tankShe leaps at a player, then dashes at the tank. Step sideways out of the dash line. [1]

Players' notes
Marked player: step out, not across the map
Move just clear of the group. Running to the far end of the arena drags the party after you and wastes time. [1]

How it's counted
Bosses are listed above in the order this route first names them.
- 1
Go inside, kru.
- 2
Go down the cliff. Watch out for the Corrupted Fairies while gliding.
- 3
Examine the nearby Kibelisks as well. It's good to bind with all the Kibelisks you come across, kru!
- 4
Avoid the poison flowers. Their scent is alluring, but dangerous.
- 5
There is a Spirit Predator just ahead! Bind with the Kibelisk first, kru!
- 6
Go defeat Tiere now, kru! Up the hill to the right!
- 7
Tiere is at the island below the hill. Glide down, kru!
- 8
Amazing. Go explore the island now, kru!
Glide down and destroy the Stone Wall blocking the path, kru.
- 9
You can go by using the Windstream.
- 10
You're in the Boulder Islands from here on out. Travel between them by flying.
There is a Kibelisk that I recommend binding with, kru.
- 11
Glide to the next island. Be careful of the Corrupted Fairies!
- 12
Use the Updraft to get up, kru.
- 13
The Spirits are defending the Barrier. Defeat them, kru!
- 14
Go to the next island. There's a shortcut at the hilltop.
- 15
Almost there. Don't forget to bind with the Kibelisk, kru!
- 16
Use the Updraft. You need to ride the Windstream as soon as you reach the top.
Now, kru! Glide to the Windstream!
- 17
There's another Windstream at the end of this Windstream, kru! Ride it if you want to take the shortcut!
- 18
The Island Warden is on the hilltop! Defeat him, kru!
- 19
Go meet Vakron now, kru. I recommend binding with the Kibelisk beforehand.
- 20
Now you can disable Vakron's barrier, kru!
- 21
In this area, you'll have to activate the altar by absorbing Odyle while flying, kru.
You may only activate the altar for a short duration after absorbing Odyle, so be careful, kru.
You could die if you fall, so maintain your Flight Power by absorbing feathers, kru!
- 22
This is the last Kibelisk. Bind with it, kru!
- 23
This is an Odyle Energy Cube!
The guide's briefing (7 lines)
I figured we'd cross paths again, kru. Who else but us two would venture this far?
Hey Daeva, are you familiar with the Spirit Realm, Etheria? I thought so, kru. That'll make things easier.
This land belongs to Vakron, the Boulder Lord of Etheria. He showed up without warning and took over the place through sheer might, kru!
I don't know what's happening inside Etheria, but he's furious, saying he'll capture the spirits of Atreia and take them away, kru!
Of course, he won't be happy to see us. But we still have to explore this place, kru!
Etheria's influence has filled this place with mystical energies and unusual plants and animals. Finding them is what the Shuliman Expedition was formed for, kru!
So, will you join me this time, too? As always, a grand reward awaits you!
How this page is made
Game files (client 2026.10.21 (Steam build 26077854, 2026-10-21)): the lines the game shows when a boss casts or uses a skill, gets a buff, starts or dies (NpcBehaviorCase → NpcTalk: “Guide” = the Shugo guide's hint in the Exploration run, “Boss” = the boss's own shout), the skill's name, cast time, cooldown and range (Skill), the buffs and debuffs it applies with the game's text (SkillEffect → SkillAbnormal), the Frenzy timer (NpcData.BossBerserkInvokeTime) and the stagger. Many boss skills are only called “Attack” in the files; those cards are named by their effect or by the action they ask for. HP thresholds are not in the client.
The action label on each card is our reading of the guide's line, by its words: the first that matches of “Big alone, small together”, “Stagger it”, “Stop attacking”, “Break free”, “Climb up”, “Jump”, “Take cover”, “Block it”, “Lure the boss”, “Colours”, “Kill it first”, “Stack up”, “Spread out”, “Find the gap”, “Get in”, “Move out”, “Burn it down”. The line itself is the game's.

Vakron Sky Island guide FAQ
How do you beat Tiere in Vakron Sky Island?
The game's guide says: “Tiere will create poison clouds! Defeating the Rafflesia will neutralize the poison clouds” Players add: Do not stack early — Stay loose during the normal part of the fight. Clump up only when Tiere jumps to the middle and a flower appears. Kill the flower, stand in its zone at ~75% HP — When she jumps to the centre, everyone gathers, kills the flower and stands inside the purple antidote zone it leaves. That zone clears the poison debuff.
How do you beat Vakron in Vakron Sky Island?
The game's guide says: “Vakron traps nearby enemies within thorns! You'll need to rely on your comrades to free you” “Vakron will attack after trapping you! Destroy the rocks and escape” “Getting hit by this attack might take you out! Dodge by jumping” Named skills: Lodestone Prison (4.5 s cast) and Surging Thorn. Frenzy after 5:00 (Conquest, Conquest [Hard]). Players add: Kill timer — Conquest has an enrage at about 5:00. Normal groups rarely hit it, but a weak group can. Root and thorn prison — One player is marked and must step away from the group; when the mark ends they are locked in a prison, and anyone near them too. The group breaks it fast while the healer keeps them alive. Do not abandon the rooted player.
How do you beat Thamon in Vakron Sky Island?
The game's guide says: “Stop using physical attacks when Thamon's body is emitting red energy! He'll just absorb the damage” “Stop using magic attacks when Thamon's body is emitting purple energy! He'll just absorb the damage” Players add: Colour aura at ~95% HP — Every 8-10 s he glows red or purple. Red: physical hits heal him. Purple: magic hits heal him. Stop that damage type while the colour lasts; hitting the wrong type refills his HP in seconds. Mixed-damage classes — Templars and Chanters deal both types. Hold the skills that match the current colour instead of stopping completely.
Is there an enrage timer in Vakron Sky Island?
Yes: Vakron goes into Frenzy after 5:00 (Conquest, Conquest [Hard]). Frenzy raises its speed and damage (the buff's text in the game files).
What is the route through Vakron Sky Island?
The guide gives 23 steps; it sends you to Tiere and Vakron in that order. On the way it keeps reminding you to bind with each Kibelisk you pass.
