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.

Interactions[edit | edit source]

  • Blood Clot Blood ClotBlood Clot Icon.pngIncreases damage by 1 and range by 5 for tears fired from the left eye. / Chemical Peel Chemical PeelChemical Peel Icon.pngTears fired from left eye do increased damage.: The stat rebalancing doesn't affect the modified tears.
  • Added in  AfterbirthD8 D8D8 Icon.png4 roomsRe-rolls Isaac's speed, range, tears, and damage.: D8's stat changes depend on which stats end up with which multipliers and their base values. Range has high weight and is uncapped, and thus can result in a massive boost if it scores a high multiplier. Damage is also uncapped but, on the other hand, has low weight.

Synergies[edit | edit source]

  • Added in  AfterbirthEpiphora EpiphoraEpiphora Icon.pngShooting in one direction increases Isaac's rate of fire until the cap is reached. As soon as Isaac changes direction or stops shooting, rate of fire is reset to its normal amount.: Damage, Speed, Range, tear weight, and Shot Speed will increase over time, up to a limit.
  • 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. Without other items, damage will be reduced to around 30% but tears will be doubled and speed maxed.
  • Added in  AfterbirthLusty Blood Lusty BloodLusty Blood Icon.pngEach time Isaac kills an enemy, Isaac's damage increases for the current room.: Slightly increases range, speed, tears, and damage per each enemy killed, up to a limit.
    • Samson's Lock Samson's LockSamson's Lock Icon.png1/15 chance to increase damage by 0.5 for the current room each time an enemy dies. has the same effect whenever it does trigger.
  • Monstro's Lung Monstro's LungMonstro's Lung Icon.pngIncreases damage and grants a charged shot that fires multiple tears in the same fashion as Monstro.: Charge time is drastically reduced, damage and speed are decreased.
  • 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. Range and damage have no cap, and range's effect via Libra is very high, whereas damage is not very impressive. Speed and tears have a hard cap which, if reached and the stat is chosen, results in no effect. Before reaching the cap, however, especially tears can provide a significant boost.
  • 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. Without other items, damage will be higher than Polyphemus PolyphemusPolyphemus Rebirth Icon.pngMakes Isaac shoot one huge tear. Also reduces Tears to minimum. Damage increased . 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.
  • Added in  AfterbirthTape Worm Tape WormTape Worm Icon.pngDoubles Isaac's range and halves his tear height.: The large Range Up from the trinket will be redistributed to the other stats and improve them.
  • 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.
    • Since Taurus TaurusTaurus Rebirth Icon.pngSpeed down; gains speed while in a room with enemies until gaining My Little Unicorn effect for a few seconds. increases Isaac's speed a set amount of times, these boost will stop after a certain amount of time spent in one room. If Isaac's speed isn't high enough, the secondary effect of Taurus won't activate itself.
    • Once a room is cleared, Isaac's stats go back to their previous values.
    • Combined with Soy Milk Soy MilkSoy Milk Icon.pngTears shrink and do much less damage, but fire in very rapid succession., Isaac will be invincible the instant he enters a room.
