Added in Repentance

Perfection is a trinket added in The Binding of Isaac: Repentance.


  • Gives +10 luck.
  • This trinket is destroyed if Isaac takes non-self damage while holding it (i.e getting hit by Monsters, walking on Spikes, getting hit by an explosion, etc.).
  • This trinket can only be obtained by clearing 3 consecutive floors without taking damage. It will drop upon the final boss room of said consecutive floors being cleared.
    • In Greed Mode, it will drop after defeating the first boss of the third floor (Depths Depths, or Necropolis Necropolis and Dank Depths Dank Depths in Repentance ).
    • While playing co-op, everyone needs to play without taking damage for the trinket to spawn.


  • Blood Donation Machines, Devil Beggars, Hell Games, Confessionals, Curse Rooms, Spiked Chests, Bad Trip pills, White Fire Places and the Mausoleum doors count as self-damage and won't destroy Perfection.
  • Every XL floor cleared counts as a single floor for the purposes of obtaining this trinket.
  • Perfection can intentionally be dropped if Isaac must take damage for whatever reason, allowing him to keep it.
  • Due to the unique method of obtaining it, Perfection can never naturally spawn as a Golden Trinket.
  • 10 Luck is coincidentally the highest amount of luck Isaac can have that would help with room clear rewards paying out.
  • If Isaac holds multiple copies of Perfection via 15►Mom's Purse Mom's Purse or 15►Belly Button Belly Button, upon taking a hit only one of them will get destroyed.
  • If Isaac gulps Perfection as he's taking damage (e.g. because of 15►Marbles Marbles), the trinket will stay in your inventory as a passive item until the next instance of taking damage.


  • 15►Blanket Blanket/Holy Card Holy Card/15►Holy Mantle Holy Mantle/Wooden Cross Wooden Cross/15►Dogma Dogma/The Lost The Lost/Soul of the Lost Soul of the Lost/White Fire Places: Losing the shield does not destroy Perfection.
  • 15►Dull Razor Dull Razor: Does not destroy Perfection.
  • 15►Sharp Plug Sharp Plug: Does not destroy Perfection.
  • 15►Rock Bottom Rock Bottom: The +10 luck persists after switching trinkets as stats are locked to their highest values ever reached after picking Rock Bottom up. However, after losing Perfection, additional luck-ups will have no effect until the luck bonus lost is made up. (The stats are still being calculated behind-the-scenes, but until it surpasses the run's post-rock-bottom luck record, the record will be used instead).
  • The Lost The Lost / Tainted Lost Tainted Lost: Since these characters are likely to die instantly after taking a single hit, Perfection is almost guaranteed to drop after the third floor boss room is cleared, and is also almost guaranteed to stay with them until their deaths.
    • This means getting luck based items at any point of the run, especially ones with luck scaling that that tops out at about 10 luck, is a very good idea.
    • The ability to Smelt/Gulp trinkets will also add to the synergy, as there are many luck based trinkets as well.


  • 15►Smelter Smelter/15►Marbles Marbles/Gulp!: The effect is still lost after taking damage.
  • 15►Blood Oath Blood Oath: The forced damage will not destroy the trinket, or prevent its acquisition.
