Cracked Crown 
Effects
- (Removed in Repentance) -20% tear delay (increased rate of fire)
- (Removed in Repentance) 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.
- (Removed in Repentance) 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) Void.
- (Removed in Repentance) The extra stat upgrades are approximately 33% of the original.
- (Added in Repentance) The extra stat upgrades are approximately 20% of the original.
Notes
- 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.
- (Added in Repentance) For damage upgrades, the 20% bonus is given to the change to Isaac's actual damage, not the damage upgrade itself.
- (Added in Repentance) 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.
Synergies
- (Removed in Repentance) (Mom's Box) Mom's Box: The tear delay reduction rises to about 36%, and the stat boost is increased to about 77%.
