Libra is a passive Zodiac item.
Effects[edit | edit source]
- 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
The Book of Belial.
- 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.
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 (
Mutant Spider,
Brimstone,
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,
The Small Rock will give no stat changes at all.
- Items that affect the stats of Isaac's tears after they're fired (
A Lump of Coal,
Blood Clot,
Proptosis, etc.) do not go through the balancing formula and work as normal.
- 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.
- 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
Mini Mush or
Kidney Stone that increase tear height but lower range are mostly detrimental.
Synergies[edit | edit source]
Soy Milk: Greatly increases DPS.
The combination on its own is almost neutral, very slightly above base level.
Ipecac: Can be rapidly fired with decreased damage.
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.
Tape Worm: Greatly increases DPS. Deadly with
Mom's Box.
Interactions[edit | edit source]
Almond Milk: The combination on its own is almost neutral, very slightly above base level.
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.
Eve's Mascara: Gives an overall stat downgrade, due to tears being weighted heavier than damage.
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.
Technology 2: Halved tear delay due to firing out of only one eye is unaffected by the balancing formula.
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.
Epiphora: The stat bonus for continuously firing in one direction applies to all stats. The accuracy penalty is unaffected.
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).
