Monke

Monke is the celestial boss-killer at a staggering 1 in 15.3 billion, and a Tier S body to match. By this point in the rarity ladder slimes are separated by grind alone, and Monke is endgame power for accounts that have already pushed their multipliers and rebirth count toward the documented ceiling rather than treating either as a casual stat to tune.

Equip Monke for the hardest documented bosses, where nothing cheaper closes the fight on a reasonable timeline. The honest comparison is to Blackhole at roughly fifteen times more common — both are boss specialists, but Monke operates in a different rarity band and is the pick once celestial pulls are realistic for your stack. After Ouchy lands, Monke is the obvious next target for any account routing toward astral tiers.

Realistically Monke is a long-horizon goal, since reaching it says more about your luck stack and patience than any single strategy choice you can make. Until Waxie or Germy is in genuine reach, Monke represents the practical ceiling for boss damage. By the time Monke joins the loadout, the only remaining hunt is the astral band, and that is a different category of commitment entirely.
