Vakron Sky Island is a party dungeon for two to five players, set on a floating island in Etheria held by the Boulder Lord and his bound spirits. It runs on a 60-minute clock across its Exploration and Conquest difficulties, and its three bosses hand out the Epic Unyielding gear set along with upgrade materials.
Quick answer: You enter at character level 45 with an item level of 1,400 in a group of 2-5, then clear Tiere, Thamon, and Vakron to open the reward cube.
Entry requirements for Vakron Sky Island
The gate for both difficulties is the same character level and item level. The item level floor is 1,400, so gear score is what actually keeps most players out early.
- Character level: 45
- Item level: 1,400
- Party size: 2-5 players
- Difficulties: Exploration and Conquest
- Time limit: 60 minutes
How to clear the dungeon
The route crosses several floating sections rather than one corridor, so you glide between islands and regroup at each landing. A permanent debuff tracks the whole run, and both mini-bosses must die before the final boss area will open.
Bosses and drop rates
All three bosses are Hero rank at level 54. The two mini-bosses share an identical loot table, while Vakron carries its own. Each chance below is the per-kill roll.
Tiere, Spirit Predator
Tiere fights in Tiere’s Nest. Around three-quarters health it floods the arena with green poison and leaves only a small safe ring near itself, then throws purple projectiles that leave pools, so the party stacks tight and rotates together until it clears the floor by leaping away.
| Drop | Grade | Chance |
|---|---|---|
 Soul Codex (Bound) | Special | 60% |
 Refining Stone | Common | 53.7% |
| Amplify Stone Fragment (Bound) | Unique | 20% |

 Balaur’s Essence | Epic | 10% |
| Hard Balaur Scale | Epic | 8.7% |
| Hard Balaur Leather | Epic | 8.7% |

 Unyielding Greaves | Epic | 5.7% |
 Expert’s Refining Stone | Rare | 5.4% |
 Unyielding Breastplate | Epic | 4.3% |
Tiere also drops Kina and bound Kina on top of the table above.
Thamon, Island Warden
Thamon waits in its own area past the cave. It summons stones that petrify anyone caught, then follows with an arena-wide shockwave, so you leave the floor telegraphs early and free a petrified ally by hitting them. Its other trick is a timed aura: a purple aura heals it from magic damage and a red aura heals it from physical damage, so stop your matching damage type while the aura is up. Its loot table is identical to Tiere’s, including the Wind Forest Ring at 11.4% and the Unyielding accessories.
Vakron, Boulder Lord
Vakron is the final boss and combines the earlier lessons. Surging Thorn sends out three expanding waves you jump, followed by a room-wide blast you glide over; Lodestone Prison pulls everyone in and walls the group in rock, where you break the red-glowing Vakron Cloaked Rock to escape. It also roots a random player, who must be freed by teammates, and on Conquest it enrages at about five minutes.
| Drop | Grade | Chance |
|---|---|---|
| Balaur’s Essence | Epic | 30% |
| Hard Balaur Scale | Epic | 26% |
| Hard Balaur Leather | Epic | 26% |
| Hard Balaur Horn | Epic | 26% |
| Amplify Stone Fragment (Bound) | Unique | 20% |
| Unyielding Gloves | Epic | 9.6% |
| Unyielding Cloak | Epic | 9.6% |
| Unyielding Earrings | Epic | 9.6% |

| Unyielding Breastplate | Epic | 4.8% |
| Wrathful Will | Unique | 3.6% |
 Unyielding Greatsword | Epic | 3.2% |
Vakron additionally drops the bound Silentium, Enhance Stone, and both Kina types with no fixed rate attached.
What the Unyielding set is worth
The Unyielding gear is the main draw. Every piece is Epic, item level 42, tier 2, carries three manastone slots, requires level 45, and is bound when obtained. Vakron rolls the full armor and accessory spread at the highest rates, while the two mini-bosses cover the same slots at slightly lower chances.
On defense, these pieces sit mid-table rather than at the top. Unyielding Boots, Cloak, and Gloves each carry 204 Defense, which ranks 14th among their respective slots; the slot leaders are the Splendent Ebony Dragon Lord and Splendent Wise Dragon Lord versions at 504. The Unyielding Helm and Pauldrons post 230 Defense, and the Unyielding Greaves top the set at 256 for the Legs slot.
Beyond gear, the run feeds materials. The Amplify Stone Fragment drops at 20% from all three bosses, and Balaur’s Essence plus the Hard Balaur Scale, Leather, and Horn come off Vakron at 26-30%, which makes the island a steady source for crafting and refining stock alongside the Refining Stone and Expert’s Refining Stone that the mini-bosses shed at high rates.
