Libra

Libra is a passive Zodiac item.

Effects

 * Continually balances Isaac's primary attributes - damage, range, tears, and speed (has no effect on luck, tear height, or shot speed).
 * This effect is NOT one time only - Libra will rebalance Isaac's attributes whenever they are changed by an item, effect, etc. including temporary effects such as the.
 * Grants 6 coins, 6 bombs, and 6 keys.

Synergies

 * : Greatly increases DPS.
 * Slightly increases base damage.
 * : Can be rapidly fired with decreased damage.
 * : Gradually increases all stats in an incomplete room. Libra prevents Isaac from becoming invincible (unless with high stats), and stat increases will remain until the end of the fight.
 * tape worm: Greatly increases DPS. Synergyzes well with.
 * Tape Worm is a flat +3 range instead of x2.
 * : Stats will increase as a result of items, get locked at the highest point, and then be balanced out via Libra allowing items like Ipecac and Soy Milk to have higher damage/shot speed respectively.

Interactions

 * : The combination on its own is almost neutral, very slightly above base level.
 * : 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.
 * 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.
 * Libra is extremely detrimental to how Dark Arts works, and should not be used together: The speed boost during the invincibility phase is transferred into attack bonuses (Which are useless as tears cannot be used), and afterwards, the temporary damage boost is divided across all of Isaac's stats, resulting in very negligible stat boosts.
 * The stat bonus for continuously firing in one direction applies to all stats. The accuracy penalty is unaffected.
 * : Gives an overall stat downgrade, due to tears being weighted heavier than damage.
 * : 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.
 * At base stats, the tear delay and damage aura give a greater stat bonus than the range or speed aura.
 * When in the aura, affects re-balanced stats rather than just damage.
 * : Halved tear delay due to firing out of only one eye is unaffected by the balancing formula.

Trivia

 * 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).
