Libra

Libra, one of the 12 Zodiac armour pieces, is a legendary chestplate. It has often been used both in full out rainbow builds and all around builds, mainly because of the incredible versatility it adds to the mix with its massive Skill Point bonuses.

Lore
"Before the invention of magical weight detectors, there was a giant pair of public scales in Cinfras. Instead of being thrown away, they were reforged to be a formidable piece of armour."

Trivia

 * Libra was previously ideal for Low-HP tank builds, although Gravity may have proven to be better in some cases. However, with the exception of its low HP boost, Libra had far less drawbacks compared to Gravity. Now, with the relatively recent patch removing all of Libra's raw defenses, this statement has to be reevaluated.
