The answer before the background

Our recommendation

Use the Fusion Machine for consumables first, then sockets and jewel upgrades, and only gamble with Chaos Combination when you can afford a worse roll. Unique weapon and armor recipes unlock through different machines as the story advances. Purple and yellow equipment can also come from bosses, ordinary loot, dealers, and the Memory Layers, so rarity color alone does not tell you whether an item has the right stats.

Potion and elixir fusion recipes

The table below reorganizes the long-running community Fusion Machine reference into a fast lookup. Names and quantities should be checked against the machine on your current platform before spending rare materials, especially on the newer Steam build.

ResultRequired materialsWhen it matters
Healing Potion S3 Leaf of LifeBasic early HP recovery.
Healing Potion M2 Leaf of Life + 2 Healing Potion SA cheap step up from the smallest potion.
Healing Potion L4 Leaf of Life + 2 Healing Potion MMid-game HP recovery.
Healing Potion XL6 Leaf of Life + 2 Healing Potion LHigh-capacity HP recovery.
Life Potion S1 Healing Potion S + 2 Fruit of CauseCombined recovery route.
Life Potion M1 Healing Potion M + 4 Fruit of CauseCombined mid-tier recovery.
Life Potion L1 Healing Potion L + 6 Fruit of CauseCombined late-game recovery.
Life Potion XL1 Healing Potion XL + 8 Fruit of CauseIngredient for Elixir.
Elixir3 Life Potion XL + 12 Root of SoulExpensive full-scale recovery item.
Supreme Elixir1 Transcendent Flower + 4 Dust of DeathReserve rare materials until the result is actually needed.
Material-saving rule

Do not convert every low-tier potion immediately. Keep enough basic recovery for the current dungeon, then fuse only the surplus required for the next tier.

The upgrades that are safe—and the ones that are not

Fusion actionMaterials or costImportant risk
Standard Jewel3 Novice Jewels + 90 copperThe resulting jewel type is not guaranteed to be the one you want.
Advanced Jewel3 Standard Jewels + 3 silver 60 copperHigher tier does not guarantee a useful stat.
Supreme Jewel3 Advanced Jewels + 15 silverConsumes nine Standard jewels before other costs.
Chaos Jewel3 Supreme Jewels + 60 silverA very expensive random-result conversion.
Add one socket8 Sharp Claw + 1 Novice JewelCommunity reference applies this to zero-socket armor; verify the selected item before confirming.
Chaos CombinationItem + 2 Magic Branch + 2 Spell Crystal + 6 Mithril + 1 Chaos Scale + coinsAttack or defense can go down as well as up.
Epic Chaos CombinationItem + 1 Transcendent Flower + 3 Palpitant Crystal + 8 Mithril + 1 Chaos Scale + coinsUses rare materials and is still not a guaranteed upgrade.
Back up before gambling

Chaos Combination is a reroll, not a linear enhancement. Check the before-and-after number and never feed it the only copy of an irreplaceable weapon without a recovery plan.

Where unique gear recipes appear

Unique gear is spread across Fusion Machines rather than sold from one permanent end-game menu. The route below is a community progression map; area access and exact machine behavior may differ after a platform update.

Gear tierRecipe categoryCommunity-listed machine area
Class DWeaponsShadow Hall, early progression
Class DArmorHakan Desert 5
Class CWeaponsNoxious Sanctum Basement 1
Class CArmorShadow Hall after Eara returns to Berkel

Possible missable recipes

The community reference warns players to collect the Hall of Afterlife Class S recipes after the Alexander fight, and the Lonely Plains or Noxious Sanctum B3 recipes after the Dark Forces fight, before crossing the next right-side transition. Treat this as a save-point warning and verify it on your build.

How yellow, purple, and Memory Layer drops work

The Steam release received fixes for item grades and the combination system after launch. Install current updates before diagnosing a machine that only produces Normal-grade items or a combination result that behaves unlike an older mobile guide.

Item routeWhere to lookHow to evaluate the drop
Yellow unique equipmentFusion, normal loot, rare-item dealers, and lamp dealersCompare the actual roll, sockets, accuracy, and build fit—not the color alone.
Purple epic equipmentRed-star bosses from mid-game onward, Memory Layer bosses, and some shop routesBoss source does not guarantee the same stat roll every time.
Hall of Salvation orbCannibal Grauple in Mist Forest 2, according to the community item referenceCheck whether its rolled magic stats beat the equipped orb.
Gladiator HelmetUncontrollable Guardian in the South Room of Afterlife, according to the community item referenceDefense and secondary rolls decide whether it is useful.
Memory Layer boss gearPost-story bosses across the five layersUse the separate boss-drop list to target a slot rather than farming every encounter blindly.

Common questions

Can Chaos Combination make an item worse?

Yes. The community mechanics reference describes it as a random attack or defense change that can rise or fall. It is not a guaranteed enhancement.

Where do Class S weapon recipes appear?

The long-running community route places Class S weapon recipes in the Hall of Afterlife. Save before important story transitions because some late recipe access may be missable.

Are purple items always better than yellow items?

No. Rarity narrows the search, but variable stats, sockets, accuracy, defenses, and synergy with your build decide which item is actually better.

Why does my Steam Fusion Machine differ from an old guide?

Many English recipe references document older mobile behavior. Com2uS also fixed item-grade and combination bugs after the Steam launch, so update the game and verify the machine screen before spending rare materials.
