Sky Fortress Accessories

The Lv211+ Sky accessory set — which base items you may use, the Topaz→Sapphire upgrade path, per-tier stats, the Sky Chaos Stone, the set bonus and base-stat imbuing.

The Sky set is the Lv211+ accessory set built from materials farmed in the Sky Fortress. A complete set is the Sky Chaos Stone plus a necklace, earrings and rings, each upgraded across four tiers — Topaz → Lazuli → Azurite → Sapphire.

Almost all of the power lives in the set bonus, and the set bonus only fires when you are wearing the Sky Chaos Stone. Read that section before you decide how much to spend on tiers.

The short version

Farm the right base accessories (see below) and identify each one before touching anything else.
Farm Sky Pearl in the Sky Fortress and fuse them into upgrade stones.
Convert each base accessory with a Sky Topaz, then climb tiers at your own pace.
Craft the Sky Chaos Stone and equip it — without it you get no set bonus at all.
Only once all of that is done, start adding a base stat.

Step 1 — start with the right base item

Sky accessories are not dropped or bought. They are converted from an accessory you already own, and the converted item keeps everything the old one had — enhancement, awakening and its random options — all the way to Sapphire.

Only six accessories in the game can be used. The conversion will happily accept many other rings, earrings and necklaces and it will succeed — but the Sky accessory it gives you back can never be identified, which means it can never be equipped, upgraded or imbued. There is no way to undo it and no way to get the item back. Use one of the six below and nothing else.

Slot	Use one of these	Notes
Necklace	Yushiva's Blue Necklace Starlight Necklace	The Yushiva piece is the stronger roll — real numeric stats instead of small procs.
Earrings	Yushiva's Red Earrings Crazy Clown Earring	Same — prefer the Yushiva earrings where you can.
Ring	Moonlight Dusk Ring Starlight Dusk Ring	You wear two rings, so you need two of these. They are the hardest part of the set to farm.

The two Yushiva pieces drop from Reviac, Master of Devildom (and from Yushiva – The Red Maiden at a much lower rate). The two Dusk Rings and the other two pieces come off the Mephisto / Lilith table. Rings are the bottleneck — plan for them early.

Identify before you convert

A Philosopher's Scroll identifies a base accessory and rolls its random options. It drops from a very large number of monsters, so it is easy to get.

You get one roll per base item, and it is the roll your Sky accessory keeps forever. There is no reroll. If you do not like what you got, farm another base item and identify that one instead — but do it before converting, because once the item is a Sky accessory nothing can change its options.

Step 2 — Sky Pearls and upgrade stones

Sky Pearl is the currency of the whole system. Every monster in the Sky Fortress drops them, and the two repeatable Sky Fortress quests pay a large lump sum on top. The rare troll hunters and the Devil Skeleton that spawns after one dies are worth far more per kill than ordinary trash.

Pearls are fused up a four-step ladder. Every step is 100% success, and you drop only the stones into the combine window:

Stone	Made from
Sky Topaz	10× Sky Pearl
Sky Lazuli	10× Sky Topaz
Sky Azurite	15× Sky Lazuli
Sky Sapphire	20× Sky Azurite

Each tier is worth ten, then fifteen, then twenty of the one below it, so the real price in pearls is 10 · 100 · 1,500 · 30,000. Taking one accessory the whole way uses one stone of every tier, which is 31,610 Sky Pearls per accessory.

Step 3 — converting and upgrading

Put the accessory and the matching stone into the combine window. Every step is 100% success and nothing is ever destroyed or downgraded:

Step	What you put in
Base accessory → Topaz	the identified base item + 1× Sky Topaz
Topaz → Lazuli	the Sky accessory + 1× Sky Lazuli
Lazuli → Azurite	the Sky accessory + 1× Sky Azurite
Azurite → Sapphire	the Sky accessory + 1× Sky Sapphire

An upgrade only changes the tier. Enhancement, awakening, random options and any base stat you have imbued all carry over untouched. There is no way back down a tier, so treat every upgrade as final.

If the combine window says nothing matches: unequip the item and take it out of storage first, submit the exact amount a step asks for (more is not accepted), keep materials in a single stack, and put nothing else in the window.

Accessory stats

These are the stats on the items themselves, and they are deliberately modest — the set bonus is where the power is. You wear two rings, two earrings and one necklace, so the ring and earring lines count twice.

Sky Rings

Tier	Level needed	HP Recovery	MP Recovery	Accuracy / M. Accuracy
Sky Topaz Ring	212	351	576	50
Sky Lazuli Ring	215	403	662	55
Sky Azurite Ring	218	452	742	60
Sky Sapphire Ring	221	508	834	65

Sky Earrings

Tier	Level needed	HP Recovery	MP Recovery	M. Resistance
Sky Topaz Earrings	211	539	636	+24%
Sky Lazuli Earrings	214	591	722	+26%
Sky Azurite Earrings	217	640	802	+28%
Sky Sapphire Earrings	220	696	894	+30%

Sky Necklaces

Tier	Level needed	HP Recovery	MP Recovery	M. Defence
Sky Topaz Necklace	213	719	889	1032
Sky Lazuli Necklace	216	771	975	1152
Sky Azurite Necklace	219	820	1055	1272
Sky Sapphire Necklace	222	876	1147	1392

Tiers in each table, top to bottom: Topaz · Lazuli · Azurite · Sapphire.

The in-game tooltips show the wrong level. Each accessory's tooltip names the next tier at a level 8 higher than the item actually needs — it was written for an older level curve and never corrected. The table above is what the server enforces, so a Sapphire necklace really is wearable at 222, not 230.

Magic Resistance on the earrings scales the magic avoid you already have rather than adding flat points, so a character with low Mentality gets less out of it. Magic Defence on the necklace is a flat addition and is unrelated to it.

A full Sapphire loadout — two rings, two earrings and a necklace — comes to 3,284 HP Recovery, 4,603 MP Recovery, +130 Accuracy and M. Accuracy and +1,392 M. Defence. None of these items carries Strength, Vitality, Agility, Dexterity, Intelligence, Wisdom, attack, critical or block. All of that comes from the set.

The Sky Chaos Stone

The Sky Chaos Stone goes in the chaos stone slot and is the key to the whole set — every stage of the set bonus requires it. It is crafted in one step, at 100%:

Item 1	Amount	Item 2	Amount	Result
Sky Chaos Stone Fragment	100	Sky Pearl	100	Sky Chaos Stone

Submit exactly 100 of each. Fragments drop from Sky Fortress monsters at a very low rate, but the end-of-run chest in Brighten Maze hands a few to everyone in the instance on a good share of runs — that is by far the faster route.

The Sky Chaos Stone does not store Lak. While you are wearing it your Lak capacity is zero and you collect none. There is only one chaos stone slot, so this is a straight choice: the ordinary

Chaos Stone carries your Lak but gives no Sky set bonus whatsoever, and the Sky stone gives the full bonus and no Lak. If you are switching off a loaded ordinary stone, spend your Lak first — the game will not let you unequip a chaos stone that still holds any.

The set bonus

This is where essentially all of the power is, and it is far larger than the item stats. The three rows stack, so wearing the stone plus all three accessory types fires all three at once:

Equipped	This row adds
Sky Chaos Stone + necklace	Strength, Vitality, Agility, Dexterity, Intelligence, Wisdom +100 · Critical Damage +5 · Critical Rate +30 · P. Def +5000 · M. Def +5000
… + earrings	Strength, Vitality, Agility, Dexterity, Intelligence, Wisdom +20 · Critical Damage +6 · Critical Rate +10 · P. Atk +100 · M. Atk +100
… + ring	Strength, Vitality, Agility, Dexterity, Intelligence, Wisdom +30 · Critical Damage +9 · P. Def +5000 · M. Def +5000 · P. Atk +200 · M. Atk +200

Everything together is +150 to all six stats, +40 Critical Rate, +20 Critical Damage, +10,000 P. Defence and M. Defence, and +300 P. Attack and M. Attack.

The necklace and the Sky Chaos Stone are both mandatory. They appear in all three rows, so without either one you get nothing — not a reduced bonus, nothing. Stone plus rings alone gives nothing. Stone plus earrings alone gives nothing.

Tier does not matter to the set bonus. A Topaz necklace unlocks exactly the same bonus as a Sapphire one. Four cheap Topaz pieces plus the stone beat one lonely Sapphire piece by an enormous margin — build breadth first, then raise tiers. Three Topaz conversions cost 30 Sky Pearls in stones and deliver the entire bonus above.

A second ring or a second earring adds its own item stats again, but adds nothing further to the set.

Adding a base stat

Any Sky accessory, at any tier, can carry one imbued stat — Strength, Vitality, Agility, Dexterity, Intelligence or Wisdom (no Luck) — climbing in steps of +10 up to +90. With five accessory slots that is up to +450 of a single stat.

The stat is permanent. There is no way to remove or change it once it is on the item. Decide before you spend anything. +90 is the ceiling — the steps beyond it in the game data need an item grade that does not exist on this server.

Buying the materials

Luciad Executive Officer near Rondo Citadel trades for Luciad Medal:

Item	Cost in Luciad Medal
Imbuement Ore	10
Recipe for Strength	10
Recipe for Vitality	10
Recipe for Agility	10
Recipe for Dexterity	10
Recipe for Intelligence	10
Recipe for Wisdom	10
Gold Rondo Medal	30
Silver Rondo Medal	20
Bronze Rondo Medal	10
Cloak of the Rondo Commander	50
Sub-Guild Master Appointing Ticket	100

Two things worth knowing about that shop: it gives you one unit per click with no bulk option, and it only counts your first stack of medals. If your medals are split across several stacks it will claim you cannot afford something you clearly can — merge the stacks first.

Crafting the Essences

Each Recipe makes one Essence of that stat, at 100%:

Item 1	Amount	Item 2	Amount	Result
Recipe for Strength	1×	Sky Pearl	10×	Essence of Strength
Recipe for Vitality	1×	Sky Pearl	10×	Essence of Vitality
Recipe for Agility	1×	Sky Pearl	10×	Essence of Agility
Recipe for Dexterity	1×	Sky Pearl	10×	Essence of Dexterity
Recipe for Intelligence	1×	Sky Pearl	10×	Essence of Intelligence
Recipe for Wisdom	1×	Sky Pearl	10×	Essence of Wisdom

The imbue ladder

Put the accessory, the Essences and one Imbuement Ore into the combine window. The number of Essences grows with every step, and so does the chance of failing:

Step	Essence of Strength (or your chosen stat)	Imbuement Ore	Success
+10	10×	1×	100%
+20	20×	1×	70%
+30	30×	1×	60%
+40	40×	1×	50%
+50	50×	1×	40%
+60	60×	1×	30%
+70	70×	1×	20%
+80	80×	1×	15%
+90	90×	1×	10%

Materials are consumed before the roll. A failed attempt destroys every Essence and the Ore you submitted and leaves the accessory at its previous step. The accessory itself is never broken or downgraded — but the loss is real, and at the top of the ladder it is 90 Essences a try.

Across the whole ladder that averages out to roughly 2,280 Essences to bring one accessory from nothing to +90 — about 22,800 Sky Pearl and 23,000 Luciad Medal. That is far and away the most expensive thing on this page, so leave it for last.

Harmless display quirk: the tooltip prints the imbued stat line twice. You have the bonus once.

Random options

Sky accessories themselves roll nothing. Every random option on a finished Sky accessory came from the base item's identify roll and was carried across the conversion — which is why step 1 above matters so much.

From	What it can roll
Yushiva's Blue Necklace	+15% damage against one race · additional elemental damage 300–5,000 · a chance of P. Defence 357–647
Yushiva's Red Earrings	−15% damage taken from one race (or −5% from everything) · one of HP/MP Recovery, Accuracy, M. Accuracy, Attack Speed or Cast Speed · a chance of Evasion
Moonlight Dusk Ring / Starlight Dusk Ring	Two proc slots instead of flat stats — life steal on critical, Smite, an attack buff on hit, stun or silence chances, Creature Mastery and Taming
Starlight Necklace / Crazy Clown Earring	Weaker versions of the same idea — 12% single-race damage lines and defensive procs

What it all costs

Goal	Sky Pearl	Also
Full set bonus on Topaz pieces	30	3 base items + the Sky Chaos Stone
Sky Chaos Stone	100	100× Sky Chaos Stone Fragment
One accessory, base → Sapphire	31,610	1 identified base item
All five pieces → Sapphire	158,050	5 base items
One accessory, 0 → +90	~22,800	~2,280 Recipes and ~34 Imbuement Ore on average — about 23,000 Luciad Medal

Recommended order: the Sky Chaos Stone and three Topaz pieces first — that is the entire set bonus for almost nothing. Add the second ring and earring next. Raise tiers after that, and imbue last, once everything else is finished.
