Ouchy

Ouchy is the first celestial slime, and the rarity is genuinely brutal at 1 in 4.39 billion. The payoff is a Tier S premier attacker for accounts that have effectively maxed their luck stack already, so reaching Ouchy at all is a flex, and equipping it means most documented content folds quickly to whoever is swinging it across a typical run.

Equip Ouchy as soon as it drops, because the rarity gap from the secret tier is large enough that holding it back makes no sense. The honest comparison is to Ember at roughly half the rarity — Ember covers most active damage cleanly, and Ouchy is the pull that proves your account is operating in a different rarity band entirely. After Ouchy lands, the active loadout finally includes celestial damage rather than secret-tier substitutes filling the slot.

Until your rebirth multiplier and luck stack are genuinely deep, chasing Ouchy is aspirational rather than active. By the time Sunny or Monke arrives, Ouchy has paid for its long luck-window cost in zone clears many times over. Treat it as a long-term ambition rather than a near-term target you can plan around the way you do for prismatic pulls.
