Lumi Master/Lumis

Royal Slime

Rating 88RoyalBattle

Verdict

SituationalOnly for slime teams. Outside one it is a plain body.

Why this tier: Slime teams end on Royal Slime, the S-rank closer, because King's Command gains 50% damage per fallen slime on your side. Outside one it is a plain 96-stat body.

How to use Royal Slime

Save Royal Slime for a slime team, where it closes, because it is a poor pick outside one. King's Command gains 50% damage for every slime on your side already knocked out, so it goes in last, after the Gels have spent themselves. King's Might adds Slime Power based on which slime types share its side.

A flat 96 in ATK, DEF and HP is fine but plain. Without fallen slimes the signature is an ordinary 80-power hit, so only build it once you have the slimes. Dark and Psychic hit it for double.

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%.
