The Binding of Isaac: Rebirth Greed Mode Guide
Complete Greed and Greedier mode guide — wave mechanics, shop strategy, donation machine unlocks, and character recommendations for The Binding of Isaac: Repentance+.
Greed Mode is a wave-based survival game mode separate from normal runs. Instead of exploring procedurally generated floors, you fight eleven waves of enemies in a single arena with a shop in the center. After each wave, the shop restocks with new items from the Greed mode item pool. Coins drop from enemies and machines, creating a unique economy where spending power directly competes with survival. Greedier mode adds harder waves and a final Ultra Greed boss fight.
How Greed Mode Works
Select Greed Mode from the main menu character screen. Each character has independent Greed mode completion marks. Waves escalate in difficulty — early waves spawn basic enemies, later waves introduce champions, mini-bosses, and boss-tier threats. The shop in the center offers two items per wave from the Greed pool, plus pickups like keys, bombs, and hearts. Shopkeepers can be bombed for additional coins. There are no treasure rooms, devil deals, or angel rooms — the shop is your only item source.
Greed vs Greedier Mode
| Feature | Greed Mode | Greedier Mode |

| Unlock | Available from start | Donate 500 coins to Greed machine in Greed mode |
| Difficulty | Challenging but manageable | Champions every wave, harder enemy mixes |
| Completion mark | Greed mode mark on character sheet | Greedier mark (required for Dead God) |
| Donation machine | Unlocks Greedier at 500 coins | Continues to 999 for special rewards |
Shop and Economy Strategy
The cardinal rule of Greed mode is buy early, survive late. Items purchased in waves 1–3 define your build for the remaining eight waves. Prioritize damage and defense over hoarding coins — unused coins have zero value if you die. Key items include Hive Mind (fly synergy scales with wave spawns), Piggy Bank (coin drops on damage), and any item that provides room-clearing damage like Brimstone or Technology. Restock machines in the shop can be bombed to refresh inventory when you have excess coins.
- Wave 1–3 — Buy your core damage item immediately. Skip utility unless it synergizes with your character.
- Wave 4–7 — Add defense: soul hearts, orbitals, or HP ups. Champions appear frequently.
- Wave 8–11 — Only buy if the item is run-winning. Focus on dodging and using existing synergies.
- Ultra Greed (Greedier) — Save bombs for the boss. High DPS builds melt her; low DPS needs patience and dodge skill.
Best Characters for Greed Mode
Azazel starts with flight, short-range Brimstone, and high damage — the strongest Greed mode character for beginners. Lilith begins with the Guppy head familiar that scales with wave density. Keeper uses coins as health, synergizing with Greed mode's economy. The Lost can take free devil deal items in the shop when they appear as HP-cost items. Tainted Keeper is glass cannon incarnate but can generate infinite coins with the right setup. Watch our Greed mode video guide for donation machine strategies and Holy Mantle unlock tips.
The Greed mode donation machine in the shop persists across all runs. Donating 500 coins total unlocks Greedier mode globally. Continuing to 999 coins unlocks the Special Shop Key and other rewards. Many players use Azazel or Keeper runs to farm coins efficiently. Greed mode marks are required on every character for Dead God completion — plan dedicated Greedier sessions for your weakest characters early in your progression.
Frequently Asked Questions
How do I unlock Greedier mode?
Donate 500 coins total to the Greed mode donation machine in the shop. The machine appears in the center of every Greed mode run.
Do Greed mode unlocks carry to normal runs?
Items unlocked through Greed mode donation milestones enter the global item pool for normal runs. Character Greed marks are separate from normal completion marks.
Can I take devil deals in Greed mode?
There are no devil or angel rooms in Greed mode. However, shop items that normally cost HP (devil pool items) can appear and be purchased with health containers.
What is the best strategy for Ultra Greed?
Stack damage early and save 2–3 bombs for the boss fight. Orbital familiars and contact damage items work well since Ultra Greed has a large hitbox and stays relatively stationary.
