Seeker Brood has 20 health and spawns in the Mistlands.
It resists blunt, slash and pierce; spirit does nothing to it at all.
It has one attack, 60 pierce.
Of everything craftable, 
Lightning Strike, 
Frostfire Crossbow and 
Frostfire Sledge put the most damage through what it resists.
Seeker Brood is the larval form of the 
seeker, 20 health, packed into nests inside Infested Mines and hatched in bulk by 
The Queen during her fight. It bites for 60 pierce in a 1.7 meter arc every 3 seconds, two thirds of an adult seeker's pincer damage from a creature with a tenth of the health. It carries the full adult resistance set, blunt, slash and pierce resisted and spirit ignored, so a swarm takes considerably longer to clear than 20 health apiece suggests. Half of them drop one 
Royal Jelly, and nothing else.

Each 64 m zone keeps its own timer per entry and rolls the chance once per interval while loaded; a zone never loaded before rolls the moment you arrive. The spawn lands 40 to 80 m from a player, never inside a base unless noted, and "max near you" counts the loaded area around that zone. Dungeon and camp spawners are separate and not counted here.
With devcommands enabled, this spawns Seeker Brood in front of you. The third number is the level: 3 spawns a 2-star.
