How to use Umbralym
Umbralym poisons on its way out: Dark Gel poisons its final opponent twice on the knockout, and Poison Swamp or Toxic Spread add more before it goes. That feeds a Muskyx or Netherfang behind it. Detonating at high HP gives the biggest hit. Its stats stop at 85, which is weak. Muskyx is the real Dark carry.

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%.
