Verdict

SkipDon't level it as a fighter. Rushalo, its evolution, is the one worth leveling.

Dest.

Why this tier: Buffalf ranks D since 75 ATK means it cannot threaten anything, however sturdy Water Barrier and 100 DEF make it. Rushalo, its evolution, is the version worth leveling.

Buffalf's skills

Fixed kit always on Buffalf, can't be swapped

Trait · passiveWater Barrier

While on the field, whenever it gains Wet it also gains the same number of DEF stages.

Signature skillCalf Splash

Hits the current enemy and gives every Lumi on your side of the field 1 Wet.

WaterCost 5Power 40

Basic attackBovine Horn Strike

Its automatic attack: a Water hit every 0.9s for 9 power. That is among the quickest on the roster, and since every basic attack in the game trades power for interval at the same rate, the short gap buys extra hits rather than extra damage — which is what per-hit effects key off.

How to use Buffalf

Buffalf's Water Barrier turns every Wet into a DEF stage, and Calf Splash gives your whole side a Wet, so it gets tougher with each cast. 100 DEF on top is sturdy. 75 ATK is among the lowest in the game, so it deals almost nothing. Rushalo keeps the trait with more DEF; evolve it rather than building here.

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%.
