At a glance

Cest.

Why this tier: Libret is C because Flying Scale can strip your own buffs as easily as the enemy's. Stellalibra turns the same scale into triple power, so level toward it.

How to use Libret

Libret's Flying Scale flips a coin for 2 Energy: heads strips a stack from every enemy buff and stat boost, tails strips its own. Libra Gleam I shifts those odds, and Healing Light is already in its pool. 90 ATK and 90 DEF are weak past the early game. Stellalibra turns the same scale into triple power, so keep evolving.

Recommended build

The game's own in-client line-ups run Libret with Fortify equipped: 3 official setups below, plus the materials it levels, stars up and evolves with.

Each column is the species' own Min–Max range at its reference level — the exact spread the in-game Aptitude tab shows (an individual catch rolls somewhere inside it). See the Stat Rankings to sort the whole roster by any of these. Attack Speed is the Skill tab's Attack Interval: the seconds between automatic basic attacks, fixed per species, so lower is faster. Every basic attack deals the same damage per second, so a quicker one lands more hits rather than more damage, which is what on-hit effects care about. Each Swift stack speeds it up by 10% and each Paralysis stack slows it by 10%.
