The Overlord's Cradle is a Demon Unique staff with no boss attached: it drops in Adventure Mode once you are level 76 or higher, and keeps dropping there however far you go. Every copy is item level 81, and there 0.5% of what falls comes up Unique. It is built on Perfect Spiritcaller Staff — step 6 of the Spiritcaller Staff line, item level 80 and up.

It always rolls the same numbers: +96 Power, +15% Ultimate Generation, +16 Power, +60 Maximum Health, +10% Power, +51% Ultimate Generation and +27% Cooldown Recovery.

One Unique drop in 40 is a Mythical copy: the same item carrying 15–25% Mythical Energy that boosts every stat on it and can never be changed; the 15% floor is 10 times as common as the perfect 25%.

On top of that it carries The Overlord's Cradle — Your Main sustains 2 more summons and they last 50% longer, at -10% damage.

Wearing it hands you Spirit Seed and Grand Convergence.

“Grown from a seed the Overlord swallowed and could not keep.”
