Bloody Lust

Bloody Lust is an unlockable passive item.

Effects

 * Damage increases as Isaac receives damage. The damage increase stays for the whole floor, but resets upon entering a new floor.
 * The first three times Isaac is hit, his damage is increased by 0.5.
 * The next three times Isaac is hit, his damage is increased by 33%.
 * Any damage taken past the sixth hit does not further increase damage.
 * Isaac becomes redder as his damage increases.

Synergies

 * Dull Razor - Safely provides the damage boost without needing to actually take damage.
 * IV Bag - Allows Isaac to increase his damage at any time at the cost of red hearts.
 * Libra - As Isaac's damage increases, the rest of his stats increase as well, though they will reset at the start of a new floor.
 * Placenta - Provides a 100% safe, albeit extremely time-consuming, method of maxing out the damage boost free of charge. Simply take the necessary hits and wait for Placenta to regenerate the lost health.

Trivia

 * In the original Binding of Isaac, Bloody Lust only lasted for one room and the damage increase was triggered by killing enemies.
 * Lusty Blood now has the effect of the original Bloody Lust.
 * On the character select screen, Samson's starting item is spelled as "Blood Lust".
