Jujutsu Farm: How to Upgrade Characters and Boost Earnings

Quick answer

Select a character you have placed on your plot and click the upgrade button attached to its plot display. Every level you buy raises the cash that character earns per Orb, and the button shows the exact price of the next level before you pay.

• A freshly placed Star Nanami at Level 1 showed a $4.21K price for the Level 1 → 2 upgrade.
• Clicking the button repeatedly chains levels back to back — one player took a Nanami from Level 1 to Level 29 in a single session.
• That same Nanami earned $18.50K per Orb at Level 1 and $1.90M per Orb at Level 29 — roughly a hundredfold more.

Upgrading is a direct way to turn cash into income in Jujutsu Farm. The upgrade control lives on the character itself, needs no items, and each level you buy boosts what that character earns. Here is how the button works and how much earnings actually go up.

How to upgrade a placed character

The upgrade button is attached to a placed character's plot display. Characters come from Sealed Cubes: open one to unlock a Jujutsu Kaisen character, place it on your plot, and from that moment it starts generating money with the upgrade button attached to its plot display.

1. Find the upgrade button on the character's plot display. It shows the price of the next level — a newly placed Star Nanami at Level 1 displayed "$4.21K Lv 1 → 2".
2. Click the button to buy the next level. The displayed cash price is paid and the character's level increases immediately.
3. Keep clicking to stack levels. Nothing is required between levels, so you can chain upgrades back to back while you can afford them — one observed run went from Level 1 to Level 29 on consecutive clicks.

How much upgrading raises earnings

Every level boosts the character's income. The game's official How to Play text says "Upgrade your characters and BOOST your earnings", and third-party guides describe it the same way: upgrading raises how much each placed character earns.

A character's income is counted per Orb, so the figure to watch on its display is cash per Orb. One observed session with a Star Nanami from the Mahito's Experiments cube shows the scale of the climb:

That is roughly a hundred times more cash per Orb from the same character. The exact numbers come from a single session, so treat them as a realistic example rather than a fixed rate — the rule behind them is what counts: each level you buy pushes the per-Orb figure higher, and you can watch it climb on the display as you click.

The level cap

Upgrades have a ceiling. In one late-game session the ceiling was Level 35, shown on screen as the current cap, and every deployed character had been raised to it:

Even at the same level, the four characters earned different amounts, ranging from $9.56M to $12.52M per Orb. The cap was labelled "current", which leaves room for updates to move it.

How upgrading fits the progression loop

Upgrading sits at the center of Jujutsu Farm's core loop. Characters unlocked from Sealed Cubes generate money on your plot; upgrading boosts that income; and the money they earn pays for better cubes, which give you a chance at stronger characters to place and level up. Each pass around the loop funds the next.

If your cash cannot cover the next upgrade yet, the money guide covers the earning side, and the characters list can help you pick which character to invest levels in.
