Kachua and shadow gear
On Sol, shadow gear comes mostly through Kachua's Secret Keys. Keys come from instance clears and field MVPs; each key gives a Mileage Coupon, and coupons buy shadow sets in the Mileage shops. Sol makes the shadow rows cheaper and lets you choose the mix-set piece.
Keys
| Source | Keys |
|---|---|
| Instance clears (from the Instance Manager) | 1 key for each of your first 3 clears a day, 8 keys at the 5th clear of the week, plus 5% / 7% / 10% / 15% per clear on Normal / Hard / Nightmare / Hell. Details: Clear rewards |
| Field MVPs (those with a permanent spawn) | level 50-99: 20%, 100-149: 35%, 150-199: 50%, 200+: 65% per kill |
The MVP chance is the final chance, shown in @mobinfo; Advanced Looting and instance modes can raise it. Instance
MVPs do not drop keys (the clear pays instead).
The box and the coupons
Kachua's Secret Box stands in the hub (group Shadow Gear, first row) and at its official spot (sec_in02 126,178).
Each key used gives one [Kachua] Mileage Coupon, always, plus one random prize from Sol's prize pool below. You
can open ten keys at once.
The prize pool
One prize per key. Out of every 100 keys, on average (2026-10-13: Blacksmith's Blessing 20 and the new ore selector boxes; Gold, the Golden Diamond Box, the two rough ore boxes and the Care Package Era I and II boxes left the pool; 2026-10-14: the Shadow 9 Refine Hammer and the Permanent Card Remover joined, more hammers, fewer Bloody Branches):

| Advanced Refining Certificate Envelope | 0.05 |
The two permanent wings and the permanent mirror are announced to the server when someone wins one.
The two Refining Certificate Envelopes give safe refine certificates for the Refine Master (hub, group Refine and Grade; see Services).
Tunkarom (the hub's Cat Hand Salesmen, group Shadow Gear, and at the Item Mall itemmall 41,55) takes one Furious Weapon Coupon for any of
the 38 Furious weapons or one Furious Crown Coupon for any of the 18 Furious crowns, nothing else needed.
Coupons are spent at the hub's Cat Hand Salesmen (group Shadow Gear). The Item Mall's Macaroon is closed on Sol.
Since 2026-10-14 the shadow pieces come in selection boxes: buy a box, use it and pick one piece (closing the menu keeps the box). kRO's cubes gave every piece of a list at once; those are gone from the shops (cubes you already have still open as before).
| Entry | Boxes | Price in coupons |
|---|---|---|
| Shadow skill pieces by class (pick one) | One box per 3rd class: all of that class's skill shadow pieces (usually 12: four skills, three pieces each) | 4 |
| Shadow class pieces (pick one) | One box per class: that class's general shadow pieces (2 to 8) | 6 |
| 4th-job shadow selection boxes (37): one piece of the set, see 4th-job shadow sets | 15 | |
| Shadow base sets (pick one) | Penetration (Earring, Pendant, Shoes, Shield, Weapon, Armor); Race Penetration (the 5 race weapons and 5 race armors); Tempest and Race Tempest the same for magic; Mammoth; Gemstone | 8 |
The other tabs:
| Tab | Sells | Price in coupons |
|---|---|---|
| Smelting, Modification, Useful Items | Blessing and Shadow Refine Hammer boxes (3), line refine hammers, refinement cubes, Hero's Weapon Modification Boxes and more | 20 to 200, official prices |
| Shadow Exchange Ticket (Shadow Redemption Ticket) | 20 on Sol (official 50) | |
| Drop Box | The 16 mix-set thump boxes and the Almighty (Status) thump box | 35 on Sol (official 75) |
| Spellbook | One spellbook per mix set: one random-option roll on that set's pieces | 5 on Sol (official 10) |
| Shadow Spellbook Selection Box (Sol adds it): choose a class or skill spellbook, physical or magical | 5 |
Everything else (refine hammers, refinement cubes, modification boxes, Blessing and hammer boxes) keeps its official price. The Silit Pong Box is not sold on Sol; its place in the Useful Items tab holds the Almighty thump box (35).
Mix sets: thump boxes and selection boxes
How a mix-set piece is made: 1. Collect the set's base pieces at +7 or more (Reload: +9). Most come from that set's base cube in the Shadow Cube tab. 2. Buy the set's thump box (35 coupons) and use it: the official combination window opens and takes the base pieces the recipe needs. 3. On Sol you then get a Shadow Selection box of that set. Use it and pick the piece you want. Closing the menu keeps the box.
| Mix set | Pieces you can pick | Base pieces the thump box takes (+7) |
|---|---|---|
| Maximum Mammoth | Armor, Shoes, Earring, Pendant | all 6 Mammoth pieces |
| Full Penetration | Armor, Shoes, Earring, Pendant | 10 Penetration and race pieces |
| Full Tempest | Armor, Shoes, Earring, Pendant | 10 Tempest and race pieces |
| True Gemstone | Armor, Shoes, Earring, Pendant | 6 Gemstone pieces |
| Major Auto Spell | Armor, Shoes, Earring, Pendant | all 6 Auto Spell pieces |
| Lord Bearer's | Armor, Shoes, Earring, Pendant | 6 Bearer's pieces |
| Spell Caster | Armor, Shoes, Earring, Pendant | 6 Caster and Spell Flow pieces |
| Mega Blitz | Weapon, Shield | all 6 Blitz pieces |
| Durable | Weapon, Shield | all 6 Physical pieces |
| Clever | Weapon, Shield | all 6 Magical pieces |
| Absolve | Weapon, Shield | 5 Spiritual and Malicious pieces |
| Perfect Size | Weapon, Armor | 3 size pieces (Big, Medium, Small) |
| Almighty | Earring, Pendant | 5 stat pieces (Power, Int, Dexterous, Vital, Athletic, Lucky) |
| Infinity | Infinity Shadow Weapon | Infinity Earring and Pendant |
| Hasty | Infinity Shadow Weapon (as in the official data) | 2 Hasty pieces |
| Reload | Separate Reload Shadow Shield | 3 Reload pieces at +9 |
The Experience thump box is sold but cannot be used (its recipe is missing in the official data). Do not buy it.
Many basic pieces (stat, race, Physical, Magical, Blitz, Infinity) also come from the official MVP "Mysterious Combination" recipes, as on official servers.
Shadow spellbooks
A spellbook gives a shadow piece new random options without touching its refine level. Double-click the book: the upgrade window opens; put the piece in (it must be in your bag, not worn, without cards). The piece's old options are replaced, and the book is used up.
- The 17 mix-set books (Almighty, Major Auto Spell, Hasty, Durable, Perfect Size, True Gemstone, Experience, Clever, Infinity, Lord Bearer's, Mega Blitz, Absorb, Maximum Mammoth, Full Temperament, Reload, Spell Caster, Trait Status) work on their set's pieces refined up to +10, and give one or two options (a second one about half the time):
- first (defensive): resistance to one element +2-3 % (Neutral 1-2 %, all elements 1-2 %), or 2-3 % less physical or magical damage from monsters of one size (Almighty, Lord Bearer's and Hasty: 3-5 % less physical damage);
- second: 1-2 % less physical or magical damage from monsters of one element, or 1-2 % less damage from normal or boss monsters.
- Class and Skill spellbooks work on the class shadows and the 3rd-job skill shadows (any refine), and give one option:
- physical book: ATK +1-15, ATK +1-3 %, ASPD +1, ASPD +1-5 %, HIT +5-15, Critical +1-15, critical damage +1-5 % or long-range damage +1-5 %;
- magical book: MATK +1-15, MATK +1-3 %, variable cast time -1-3 %, healing +3-5 %, healing received +3-5 %, Max SP +20-100 or Max SP +1-2 %.
The books' official text names no options, so Sol uses the official shadow option tables (the value ranges are kRO's own); they may change once the official numbers are known.
Shadow items from field MVPs
Field MVPs with a permanent spawn also give shadow items (final chance; like the key, the era box and the costume rows they go straight to the inventory of the MVP player, by mail when the bag is full):
| MVP level | Drop | Chance |
|---|---|---|
| 100-149 | Material Shadow Cube II (two random mix-set base pieces) | 3% |
| 150-199 | Random Shadow Thump Box (one random mix-set thump box) | 2% |
| 200+ | Random Shadow Thump Box | 5% |
Shadow Recycler
In the hub (group Shadow Gear). Bring several unwanted items of the same tier, get one new roll:
| You give | You get |
|---|---|
| 5 basic pieces (stat, race, class, skill and every other non-mix piece) | 1 Material Shadow Cube II |
| 5 mix-set pieces (pieces of the sets above) | 1 Random Shadow Thump Box |
| 3 Ancient Hero weapons (any of the 38 weapons the Ancient Hero's Weapon Box gives, mixed classes allowed; not Patent or LT weapons) | 1 Ancient Hero's Weapon Box (a new random weapon of any class, Ancient Hero) |
Refines are lost, and so are a weapon's cards and enchants (the Recycler asks again before taking a refined or carded weapon). Equipped, rented or bound items are not taken. You can also sell any piece to the Surplus Buyer for 50,000 z.
4th-job shadow sets
Official servers have no normal way to get the level 200 shadow sets of the 4th jobs. On Sol each set has a selection box in the Cat Hand Salesmen's Shadow class pieces shop, 15 coupons each. Use the box and pick one piece; closing the menu keeps the box. These pieces count as basic pieces at the Shadow Recycler. These prices are a first try: Silent checks later whether this route is right, so it may move.
| Box | Pieces you can pick |
|---|---|
| Full Power, Full Rate, Full Spell | Armor, Shoes |
| Focusing, Stout, Centering, Witty | Earring, Pendant |
| Physical Power, Magical Spell, Concentration, Wisdom, Stamina, Creative | Weapon, Shield |
| Sword Master, Bow Master, Fatal Master, Magical Master, Spell Master, Sorcery Master | Armor, Shoes, Earring, Pendant |
| Dragon Knight Skill | Storm Servant and Dragonic Spear (Earring, Pendant), Hack Slasher and Madness Breath (Armor, Shoes) |
| Biolo Skill | Explosive and Acidified (Earring, Pendant), Mystery Dust and Thorns (Armor, Shoes) |
| Spirit Handler Skill | Chulho Claw and Hyunrok Cannon (Earring, Pendant), Hogogong Battering and Hyunrok Breeze Spirit (Armor, Shoes) |
| Imperial Guard, Shadow Cross, Abyss Chaser, Cardinal, Inquisitor, Meister, Windhawk, Troubadour and Trouvere, Arch Mage, Elemental Master, Night Watch, Shinkiro and Shiranui, Sky Emperor, Soul Ascetic, Hyper Novice Skill | the class's first skill set pair: an Earring and Pendant set and an Armor and Shoes set (for example Shadow Cross: Eternal Cross, Savage) |
The second skill set pair of those fifteen classes (for example Shadow Cross's Crater and Stab) is newer than Sol's game client, so it is not offered.
Master shadow gear: enchants and Shadow Essence
The Master Shadow Weapon and Shield and the M. class shadow sets have official Enchant tables; on Sol two NPCs in the hub (group Shadow Gear) open them:
| NPC | Opens |
|---|---|
| Master Shadow Smith, first enchant entry | Master Shadow Weapon and Shield; M. sets of Dragon Knight, Imperial Guard, Shadow Cross, Abyss Chaser, Cardinal, Inquisitor, Meister, Biolo, Windhawk |
| Master Shadow Smith, second enchant entry | M. sets of Troubadour and Trouvere, Arch Mage, Elemental Master, Night Watch, Spirit Handler, Shinkiro and Shiranui, Sky Emperor, Soul Ascetic, Hyper Novice |
The window shows what each slot costs. The Master weapon and shield use Shadow Essence (1 for a stat +5, 5 for a trait +3); the M. class sets use their class soul materials.
Master Shadow Smith (hub, group Shadow Gear, "Shadow Essences"): 1 Fragment of Good Will or 1 Piece of Sin for 1 Shadow Essence. The fragments drop on Thanatos Tower floors 9-12 (Thanatos Tower). The rate may change.
Master Shadow Smith: forging a Master piece
The Master Shadow Smith (hub, group Shadow Gear, the last NPC of the row) forges the M. class piece you choose:
| You bring | You get |
|---|---|
| one class shadow piece of the slot (armor, shoes, earring or pendant) refined to +9 or higher, and 10 Hell Coins | the Master piece of that class and slot (for example a +9 Hack Slasher or Sonic Shadow Armor gives the M. Dragon Knight Shadow Armor), at +0 |
- A class shadow piece is any shadow piece made for one class: the 3rd-job skill pieces (Sonic, Ignition, Cold Breath...), the 4th-job skill pieces (Hack Slasher, Storm Servant...) and the class pieces of Kagerou/Oboro, Rebellion, Star Emperor, Soul Reaper and Doram. Stat, race and mix-set pieces (Full Penetration, Maximum Mammoth...) do not count.
- The old piece's refine and enchants are used up; the Master piece comes at +0.
- Equipped, rented or bound pieces are not listed: unequip a piece first.
- The Master Shadow Weapon and Shield are not forged here: they come only from the Kachua box.
- Hell Coins come from Hell clears of level 150+ instances (Rewards).
