Lucky

Lucky is the first slime that changes how you play rather than how you fight. At 1 in 21,500 it is a real mythic chase, and its passive luck boost is why the tier list calls it essential for any luck build, since equipping Lucky makes every future roll cheaper across the entire account.

Its passive is a confirmed three-times luck multiplier, reconciled across three sources, so the payoff is verified rather than estimated. Pull Lucky early in your mythic hunt and the rest of your roster compounds on top of it: every divine, prismatic and transcendent slime you chase afterward arrives with better odds than they would have without Lucky in your active team.

This is the slime that breaks the rule that rarity tracks combat power, because Lucky is Tier A on utility alone with zero damage role to its name. By the time you are routing toward Aegis, Wicked or any divine, Lucky should already be parked in your loadout. Stop chasing higher-rarity slimes until Lucky is locked in, since every rebirth without it is a rebirth your account paid full price for and nothing else will recoup that cost.
