Quick Scoop: What Boss Items Are Usually Traded for Demon Fingers in

Jujutsu Infinite’s Cursed Market?

In Jujutsu Infinite, boss drop items (especially certain raid boss materials) are the main thing players farm and then trade in the Cursed Market for Demon Fingers , which are the core currency for progression. The most common pattern is:

Grind a specific boss → collect its unique item → trade that item in the Cursed Market for 1 Demon Finger per item (or per set).

Below is what’s usually traded.

Core Boss Items Traded for Demon Fingers

From guides and community discussions, the following boss drops are most often turned into Demon Fingers:

  • Cursed Tentacle – from the Ocean Curse raid boss (level 120+).
    • Very common “farm-and-trade” item.
    • Often traded at rates like 9 Cursed Tentacles → 1 Demon Finger in the market, or 1:1 in some updates depending on the version.
  • Volcanic Ash – from the Volcano Curse raid boss.
    • Another top boss material used in the same way as Cursed Tentacle.
  • Demonic Blob – from the Heian Imaginary Demon raid boss (level 420).
    • Higher-tier boss item, also tradable for Demon Fingers.

General rule:
You defeat a boss → get its signature material → open the Cursed Market → trade that material for 1 Demon Finger per material (or a small bundle).

How the Trade mechanic Works in Practice

The most popular method described by players is:

  1. Go to the Cursed Market in the lobby.
  2. Look for boss drop items listed as “for 1 Demon Finger” (e.g., Cursed Tentacle, Volcanic Ash, etc.).
  3. Farm that boss repeatedly (often on max difficulty with luck buffs like “SL buff” and Fortune set).
  4. Once you have enough items, trade them for as many Demon Fingers as you want.

Some players describe it as:

“Farm the boss item, and as soon as it hits the Cursed Market you can trade them for the Demon Fingers… each time you beat the boss that’s one Demon Finger.”

So the “boss item” is literally the drop you get from the boss, not a separate crafted item.

Boss Difficulty & Luck Tips (Why People Focus on These)

To make farming efficient, players usually:

  • Use highest difficulty and level for the boss.
  • Equip luck-boosting gear (e.g., Fortune set, Luck of Hat, Lucky charms).
  • Use domain/techniques just to clear the boss quickly.

With enough luck (often aiming for “2× luck”), you can get multiple boss items per fight, turning each boss kill into multiple Demon Fingers after trading.

What You Trade Demon Fingers For (Why People Do This)

Once you have Demon Fingers, the usual upsides are:

  • Domain Shards – for unlocking domains and advanced techniques.
  • Purified Cursed Hands – needed for Awakenings.
  • Maximum Scrolls , weapons, cloaks, and special keys.

So the loop is:

Boss → Boss Item → Cursed Market → Demon Fingers → Domain Shards / Awakenings / Gear.

TL;DR (Bottom Note)

  • The items usually traded for Demon Fingers in Jujutsu Infinite’s Cursed Market are boss drop materials : mainly Cursed Tentacle , Volcanic Ash , and Demonic Blob.
  • You farm these from specific raid bosses, then trade them in the Cursed Market at set rates (often 1 item → 1 Demon Finger or a small bundle).
