Cracked Crown

Cracked Crown is an unlockable trinket added in The Binding of Isaac: Afterbirth †.

Effects[]

-20% tear delay (increased rate of fire)
- Since this directly affects tear delay instead of changing the tears stat, it allows Isaac's rate of fire to go over the normal maximum rate.
- Tear delay decreases are more noticeable and are a greater increase to DPS when the tears stat is high.
Boosts speed, range, shot speed, tears and damage if they are above their base values.
- Affects stat bonuses from passive items, trinkets that are absorbed or in a second trinket slot, and permanent bonuses given by items such as Void.
- The extra stat upgrades are approximately 33% of the original.
  - The extra stat upgrades are approximately 20% of the original.

The trinket does nothing for the listed boostable stats if they are at or below the base value; the boost is calculated on the total bonus, not per item.
Luck is not affected by Cracked Crown.
For damage upgrades, the 20% bonus is given to the change to Isaac's actual damage, not the damage upgrade itself.
For tears upgrades, the 20% bonus is given to the change to Isaac's tears fired per second, not the tears upgrade itself. Items that boost tears fired per second directly are unaffected.

Mom's Box: The tear delay reduction rises to about 36%, and the stat boost is increased to about 77%.
- Golden Trinket / Mom's Box: Stat boost is increased to about 40%.

Bug!	As of update Repentance v4.0.4, this achievement and trinket will not unlock regardless of your daily challenge win streak, making it impossible to get this secret.
