Coin strategy#
| Strategy |
Details |
| Save coins early |
Do not overspend on the first 2 floors - bank 50+ coins - buy good items later |
| Items over supplies |
Unless you are nearly dead, spend coins on items rather than hearts/bombs - item upgrades are worth more than supplies |
| Donation strategy |
Deposit at least 10 coins per floor - unlocking Keeper at 1000 coins takes a lot of accumulation long term |
| Greed = more coins |
The “Greed” item makes killed enemies drop more coins - the economy improves a lot once you have it |
| Piggy Bank strategy |
The “Piggy Bank” item drops coins when hit - pair it with healing to farm unlimited coins |
| Do not over-hoard |
Coins not spent buy no fighting power - find the balance - buy 1-2 items per shop |
Recommended characters#
| Character |
Strengths |
Why recommended |
| Lilith |
Starting Incubus (copies tears) + Box of Friends |
Strongest in every mode - copied tears = double damage + Box of Friends familiar stacking |
| Azazel |
Flight + Brimstone |
Clears waves fast - flight ignores pits - the most stable and efficient |
| Keeper |
Coin health + starting coins |
Coin health = can trade health for items - the core shop-run character |
| Isaac |
D6 rerolls + extra bombs |
The D6 rerolls shop items - bombs open secret rooms |
| Judas |
High damage + Book of Belial |
Book of Belial boosts damage in the current room - efficient wave clearing |
| Samson |
Bloody Lust (damage stacks on kills) |
Wave mode = tons of kills = unlimited damage stacking - unstoppable late |
| Bethany |
Soul charges |
Soul charges fuel active items endlessly - extremely strong with Box of Friends / Book of Belial |
| Magdalene |
4 red hearts + healing |
Beginner pick - highly forgiving - good for learning Greed Mode mechanics |
Item priorities#
| Priority |
Item category |
Examples |
Why |
| S tier |
Wave-clearing AOE |
|
|
| A tier |
Summons/offense |
Box of Friends, Incubus, Hive Mind, 20/20, Mutant Spider, high fire rate items |
Summons auto-attack and stack - the more waves, the stronger |
| B tier |
Survival/economy |
Holy Mantle, Dead Cat, Greed, Piggy Bank, soul heart stacks, healing items |
Keeps you alive and solvent - but less direct combat power than S/A |
| C tier |
Single-target/utility |
Plain damage up, fire rate up, speed up, card enhancements, key/bomb related |
Basic stat boosts - useful but not game-changing |
| F tier |

Greed Mode-specific strategies#
| Strategy |
Details |
| Corner clustering |
Hide in a room corner - enemies cluster up - wipe them all with one AOE |
| Perimeter loops |
Circle the room’s edge - line the enemies up - pierce several with a piercing weapon |
| Shop refresh |
Leave and re-enter to refresh shop items - but each refresh costs coins (starting at 1-2 coins, increasing) |
| Donation rhythm |
Donate right after waves 1-2 each floor - so you do not forget later or get interrupted by the Boss |
| Save chest waves for last |
Chests dropped by chest waves can wait until after shopping - avoid opening duplicate items |
| Do not rush the Boss |
Buy everything from the shop before the Boss - no buying after it dies |
| Use pills/cards promptly |
Spend pills/cards/trinkets between waves - do not hoard them - Greed Mode moves fast |

Greedier is the hard version of Greed Mode - unlocked by defeating Ultra Greed in Greed Mode

Greedier Mode strategies#
| Strategy |
Details |
| The first two floors decide it all |
Greedier’s first two floors are the most critical - survive and grab core items or the run is over - a weak start on the first two floors = restart |
| Double-careful positioning |
Doubled enemy damage = mistakes cost dearly. Do not overextend - positioning first |
| Prepare for double Boss waves |
Double Boss waves on later floors are extremely dangerous - keep one screen-wide trump card (a Devil Card / nuke-style item) |
| Tighter economy management |
Pricier items + higher refresh fees = every coin must be budgeted. Refresh less early, shop hard late |
| Survival > damage |
In Greedier, health/soul hearts/shield items outrank damage items - staying alive is how you deal damage |
| A narrower character pool |
Only the strongest characters (Lilith/Azazel/Bethany) post decent win rates - most others struggle badly in Greedier |

How to fight Ultra Greed#
| Phase |
Attack pattern |
Counter |
| Phase 1 |
Fires fan-shaped coin barrages - summons minions |
Circle the room’s edge - coin barrages thin out at range. Clear minions to cut interference |
| Phase 2 |
Charge attack + 360-degree coin explosion |
Sidestep when he winds up a charge. Hide in a room corner during coin explosions |
| Phase 3 (Greedier) |
Triple charge combo + elite summons |
Predict charge paths - never stop moving. Kill elite adds first |
| General tips |
Save healing/protection items for the Boss fight |
Holy Mantle, Dead Cat, soul heart stacks - make sure you have at least 5+ soul hearts before the Boss |

Greed Mode economy guide#

Goal |
Strategy |
| Early (floors 1-2) |
Survive + bank coins |
Buy only S/A tier items. Bank the rest. Deposit 5-10 coins per donation visit |
| Mid (floors 3-4) |
Start spending to upgrade |
Buy the right items to upgrade the build. Start using shop refreshes to hunt key items |
| Late (floors 5-6) |
All-in on the Boss |
Buy anything that boosts combat power - hoarded coins are useless now. Make sure you have a healing source |
| Final Boss fight |
Save your trump cards |
If luck handed you a “Chaos Card” (Chaos Card) or “Devil Card” (Devil Card) - save them for Ultra Greed |

FAQ#
| Question |
Answer |
| Best way to farm money in Greed Mode? |
Use Lilith - with Piggy Bank and healing items you can farm coins endlessly. Or use Keeper with the Greed item |
| Can’t beat Greedier? |
Practice with Lilith in normal Greed Mode first - learn the wave patterns. Then take Lilith/Azazel into Greedier |
| The donation machine exploded? |
Past a certain total, each deposit has a chance to make the machine explode. Explosion = all coins lost. Repair it with a “Chaos Card” or just use the “Keeper” character’s built-in coin health |
| Does Greed Mode unlock characters? |
Yes - Lilith unlocks by defeating Ultra Greed for the first time. Keeper unlocks by donating 1000 coins |
| Do I have to clear all 6 floors in Greed Mode? |
Yes - 6 floors of waves + the final Boss. No shortcuts |
| Best Greed Mode seeds? |
Community favorites: GRL8 GBL7 (Technology X start) and MVKV MLP8 (Brimstone start). Note: seeds cannot unlock achievements |
