Head of the Keeper

Effects

• Enemies have a 5% chance to drop a Penny when hit with Isaac's tears.
  • The chance is not affected by Luck.
• Turns Isaac's tears into coins (cosmetic effect).

Notes

• (Added in Repentance) As of Repentance, the only way of finding Head of the Keeper is by bombing Shopkeepers or using (Added in Repentance) Spindown Dice on Papa Fly.
• Does not produce coins other than Pennies.
• Hitting the front side of enemies such as the Knight will still produce Pennies, even though the enemy does not sustain any damage. This can be exploited to produce an infinite amount of Pennies from a single enemy. This however doesn't work with lowered Hosts.
  • Enemies that spawn other enemies, Globins, or enemies that regain health can also be farmed for infinite money.
• (Removed in Repentance) Head of the Keeper does not work with (The Forgotten) The Forgotten but will work with The Soul.
• When used against Ultra Greed, the coins are spawned directly in front of him and will thus heal him very often.

Synergies

• The Ludovico Technique: Tear turns into a giant rotating coin.
• Monstro's Lung: Every tear in the burst of tears can spawn coins.
• (Added in Repentance)(Nuh Uh!) Nuh Uh!: From Chapter 4 and beyond, any coins spawned will be from the loot table of Nuh Uh! instead, with an occasional harmless black fly spawning.
• Soy Milk: Due to the Soy Milk's high fire rate and low damage, enemies can be hit many more times than usual, resulting in a larger amount of coins dropping.
• (Added in Afterbirth †) Technology Zero: Coin tears are connected via electricity. Beams of electricity can cause enemies to drop coins.
• Technology 2: Due to Technology 2's constant fire rate ((Removed in Repentance) and reduced damage), enemies are hit many more times than usual, resulting in a higher likelihood of coins dropping.
