The Spider King's Brood is a Mortal Unique staff, hunted from The Spider King once you are at Threat 20 or higher. It is one of four Exceptional drops on its list — 2.5% of the Uniques that boss gives up, about 1 in 40 — and every kill rolls the list twice. It is built on Perfect Firstseed Staff — step 6 of the Firstseed Staff line, item level 80 and up.
It always rolls the same numbers: +40 Power, +11% Ultimate Generation, +16% Power, +14% Poison Damage, +98% Power, +143% Poison Damage, +59% Attack Speed and +110% Ultimate Generation.
On top of that it carries The Spider King's Brood — Your Main is attuned to Poison and hatches 8 more wisps that Envenom and spread Contagion, but each lives 60% shorter.
It leans into Poison and Venom.
It is Mortal Arena loot.
Wearing it hands you Spirit Seed and Grand Convergence.
“The King never fights alone. He never counts, either.”
