Effects[edit | edit source]

Notes[edit | edit source]

  • The balancing is based on Isaac as the character himself, and he gains no bonuses or penalties to any stat from simply having Libra on its own.
  • The balancing formula for Libra values damage a little lower than other stats. This means a standard damage up effect will actually grant less damage than a standard speed up or range up effect will.
  • Stats are capped before Libra's balancing is applied. This means that if speed is maxed out (2.0) already, a Speed Up effect will not increase any stats at all.
  • Since tear height is not involved in the calculations, items such as Mini Mush Mini MushMini Mush Icon.pngIncreases Speed and Shot Height and decreases Isaac's size, but lowers Range. or Added in AfterbirthKidney Stone Kidney StoneKidney Stone Icon.pngRandomly while firing tears, Isaac will stop firing and turn red, where he will charge and release a lot of 'tears' in one go. In the burst of tears is a kidney stone which deals a lot of damage. that increase tear height but lower range are mostly detrimental.

  • Added in AfterbirthD8 D8D8 Icon.png4 roomsRe-rolls Isaac's speed, range, tears, and damage.: D8's stat changes combine with Libra in a way that almost guarantees a slight to moderate overall boost.
  • The Inner Eye The Inner EyeThe Inner Eye Icon.pngGrants triple shot but decreases tears. / Mutant Spider Mutant SpiderMutant Spider Icon.pngGrants quadruple shot but decreases tears.: Fire rate increases, damage and speed decreases.
  • Ipecac IpecacIpecac Icon.pngReplaces tears with explosive and poisoning projectiles fired in an arc from the mouth.: Significantly reduces Isaac's damage while significantly increasing other stats.

  • Added in AfterbirthPurity PurityPurity Icon.pngThis item will boost one of Isaac's stats depending on the color of the aura around him. The aura will disappear upon taking damage and will reappear with a random color upon entering a new room. A red aura boosts damage, a blue aura boosts rate of fire, a yellow aura boosts speed, and an orange aura boosts range.: The random increase from Purity transfers to all stats accordingly. If a stat is already high when the bonus chooses it, the increase won't be as significant.
    • The best bonus will be the -4 Tear Delay; as it ignores the 'cap' value from regular Tear Ups, all stats are significantly increased.
  • Soy Milk Soy MilkSoy Milk Icon.pngTears shrink and do much less damage, but fire in very rapid succession.: Isaac's Tears will be reduced (still faster than the normal maximum without Soy Milk) and his other stats will be increased significantly.

If tear does more damage than an enemy's life, the tear continues to travel with the extra remaining damage. and speed will be maxed. Because of the Range increase, Isaac's tears fire at a height that lets them travel over obstacles like rocks or poops.

  • Taurus TaurusTaurus Rebirth Icon.pngSpeed down; gains speed while in a room with enemies until gaining My Little Unicorn effect for a few seconds.: Isaac will keep slowly gaining damage, tears, and range in addition to speed over time.
