Effects[edit | edit source]

Notes[edit | edit source]

  • The balancing is based on Isaac as the character himself; he gains no bonuses or penalties to any stats from simply having Libra on its own.
  • The game calculates Isaac's speed, range, tear delay, and damage before using them in Libra's balancing formula. This has the following notable effects:
    • If Isaac's Speed or Tear delay are already at their internal soft caps (2.00 and 5 respectively), items that increase them specifically will give no stats.
      • The only exception would be items that decrease tear delay, and then only if Isaac's tear delay isn't at the hard cap of 1.
    • Items that apply multipliers to Isaac's tear delay (15►Mutant Spider Mutant Spider, 15►Brimstone Brimstone, 15►Dr. Fetus Dr. Fetus, etc.) can be fired more rapidly with less damage.
    • Damage upgrades become less effective. In return, speed and range upgrades now increase damage and tears. Notably, 15►The Small Rock The Small Rock will give no stat changes at all.
    • Items that affect the stats of Isaac's tears after they're fired (15►A Lump of Coal A Lump of Coal, 15►Blood Clot Blood Clot, 15►Proptosis Proptosis, etc.) do not go through the balancing formula and work as normal.
  • Libra's balancing formula values tear delay higher than the other stats and damage less than the other stats. This makes standard tears ups give more stats than a standard range or speed up, and standard damage ups give less stats than a standard range or speed up.
  • Since tear height is not involved in the calculations, items such as 15►Mini Mush Mini Mush or Added in Afterbirth15►Kidney Stone Kidney Stone that increase tear height but lower range are mostly detrimental.

Synergies[edit | edit source]

  • Removed in Repentance15►Soy Milk Soy Milk: Greatly increases DPS.
    • Added in Repentance The combination on its own is almost neutral, very slightly above base level.
  • 15►Ipecac Ipecac: Can be rapidly fired with decreased damage.
  • 15►Taurus Taurus: Gradually increases all stats during a fight. Libra prevents Isaac from becoming invincible (unless with high stats), and stat increases will remain until the end of the fight. Amusingly, Isaac will continue to turn an even darker red after he stops gaining stats.
  • Added in AfterbirthTape Worm Tape Worm: Greatly increases DPS. Deadly with Added in Afterbirth15►Mom's Box Mom's Box.

Interactions[edit | edit source]

  • Added in Repentance15►Almond Milk Almond Milk: The combination on its own is almost neutral, very slightly above base level.
  • 15►Cricket's Body Cricket's Body: Due to how Libra values tear delay, Cricket's Body gives an overall stat downgrade or upgrade depending on Isaac's internal base tear delay: At 7 or less it increases stats, at 8 or more it decreases stats.
  • 15►Eve's Mascara Eve's Mascara: Gives an overall stat downgrade, due to tears being weighted heavier than damage.
  • 15►Experimental Treatment Experimental Treatment: The greater number of stat upgrades compared to stat downgrades results in an effectively guaranteed all stats up. Health, Shot Speed, and Luck are still subject to chance.
  • 15►Technology 2 Technology 2: Halved tear delay due to firing out of only one eye is unaffected by the balancing formula.
  • Added in Afterbirth15►D8 D8: D8's stat changes depend on which stats end up with which multipliers and their base values. Range has a 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 a low weight.
  • Added in Afterbirth15►Epiphora Epiphora: The stat bonus for continuously firing in one direction applies to all stats. The accuracy penalty is unaffected.
  • Added in Afterbirth15►Purity Purity: At base stats, the tear delay and damage aura give a greater stat bonus than the range or speed aura.

In-game Footage[edit | edit source]

Trivia[edit | edit source]

  • The symbol of the scales is based on the Scales of Justice held by Themis, the Greek personification of divine law and custom.
  • Libra gives 6 bombs, 6 keys, and 6 coins, a potential reference to the Number of the Beast (666).
