Ore Boost Summary Table

Spider Boss — The Broodmother

A massive spider-like creature found in the deepest boss rooms. Uses the Factorio spidertron base as a visual template but re-skinned as an organic horror.

Description

The Broodmother is a colossal arachnid that has made its nest in the deepest chamber of the mine. Its bloated abdomen pulses with bioluminescent fluid, casting eerie shadows across the cavern walls. Thick, armored legs span the entire boss room, and its mandibles drip with corrosive acid.

Abilities

• Brood Spawn — Every 15-20 seconds, spawns a wave of 4-8 small "Spiderlings" (fast, low-HP biters) from its abdomen
• Web Spit — Ranged acid attack that slows the player's movement speed by 40% for 5 seconds
• Tremor Stomp — AoE ground slam that damages all entities within 8 tiles and briefly stuns turrets
• Enrage Phase — Below 30% HP, movement speed doubles, spawn rate triples, and attacks deal +50% damage

Stats (scale with mine tier)

Loot

Defeating The Broodmother guarantees a boss chest containing rare items, modules, and unique crafting materials scaling with tier.
