On entering battle, lowers the current enemy's ATK by 2 stages.
Lumi Master/Lumis

Verdict
InvestA safe lead for almost any squad. Pair it with a damage dealer, since it stalls and heals rather than kills.
- Why this tier
As the safest lead in the game, Rainbowdeer holds its S rank on Fortune, a self-cleanse, 100 DEF and 100 HP. With 88 ATK it stalls and heals while a teammate does the damage.

Rainbowdeer's skills
Fixed kit always on Rainbowdeer, can't be swapped
Hits the current enemy with holy light and clears this Lumi's status effects and stat drops.
Its automatic attack: a Light hit every 1.2s for 12 power. That is slower than most, so anything that triggers per hit rather than per point of damage fires less often here.
Swappable skills choose which one to equip
Hits the current enemy and heals this Lumi for 20% of its max HP.
Hits the current enemy and switches out; the Lumi coming in gains +1 ATK stage.
Hits the current enemy with an orb of light and lowers its ATK by 2 stages.
Heals every Lumi in your squad for 15% of max HP and cures all their Poison.
Hits every enemy on the field with light. Costs 3 less Energy on Electric Field.
This Lumi is knocked out; every other Lumi in your squad is fully healed and cured of status effects.
Skills marked "Used in official line-ups" are the ones the game's own in-client line-ups equip on Rainbowdeer. See those line-ups.
How to use Rainbowdeer
Rainbowdeer leads the Fortify stall team in the Arena and holds the front for most other teams too. Fortune cuts the enemy's ATK 2 stages on entry, Purifying Judgment clears its own status and stat drops, and 100 DEF with 100 HP mean it rarely drops early. Run Healing Light for the squad or Radiant Blast to keep itself up.
88 ATK won't win a race, so it needs a carry such as Stellalibra behind it. Ground is its only weakness, and it stays worth building for the whole game.
Teams with Rainbowdeer
- Baton RelayPvP · Arena ladder



Three Lumi pass one growing pile of stages down the line. Rainbowdeer cuts the enemy's ATK by 2 on entry and hands over with Call for Help, so Meteofly - Variant arrives with an ATK stage. Meteofly falls asleep as it lands, and its signature wakes it with 2 more ATK and DEF. Baton Pass then carries every stage to MEGA TOMATO, which enters in Stealth and turns them into a cheap Focus Blast at 350% crit damage.
- Tomato Stealth CloserPvP · Arena ladder



Two sturdy Lumi clear the way for one entrance. MEGA TOMATO arrives in Stealth, which raises its crit rate until an enemy skill hits it, and TOMATO Laser pushes its crit damage to 350% while Stealth holds. Rainbowdeer opens by cutting the enemy's ATK 2 stages with Fortune and trades behind 100 DEF and 100 HP. Clionia banks a Wet through Stream every time an ally casts, then leaves on Water Retreat so MEGA TOMATO comes in carrying 1 Wet.
- Free-to-Play Dragon RagePvP · Arena ladder



None of these three is a limited or pass Lumi, and there is no roar to learn. Rainbowdeer enters and Fortune cuts the enemy's ATK 2 stages. Call for Help then sends Charigon in with an ATK stage, and Draconic Terror strips 2 DEF stages from whatever it faces as it lands. Dragon Rage costs 5, takes a third stage and gains 20% Pierce for every stage the target has lost. Psykat sits on the bench: the first time one of your Lumi drops below half, Dreamy heals it 30% and puts the enemy to sleep.
- Roar BreakerPvP · Arena ladder



A team for beating roar-and-trap squads. They win by dragging your Lumi across Poison Swamp and Earth Spike, so this one ends the fight before the traps add up. Zaphound paralyses the current enemy every time it enters and Lightning Raid gains 50% crit rate per stack, on 110 ATK. Bluesaur Goma brings your own 3-Energy roar, which pulls in the enemy's lowest-HP Lumi with a DEF stage already gone. Rainbowdeer leads, cuts ATK and cures Poison across the squad.
- Fortify StallPvP · Arena ladder



Rainbowdeer walls the front while Stellalibra stacks Fortify, and Psykat never has to come in at all. Fortune cuts the enemy's ATK 2 stages when Rainbowdeer enters and Healing Light tops the squad up 15%, which buys Stellalibra the turns to cast Fortify again and again; each cast adds a stage of ATK and DEF and banks a Star for Whirl of Judgment. Psykat waits on the bench as insurance.

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%.
