Has a X% chance of birthing an Egg Sac each time it hits an enemy.

• Spider Queen's power scales directly with hit frequency — the more times it contacts enemies per run, the more Egg Sacs it generates. Prioritize high-bounce characters and passives (e.g., Rubber Headband, Wagon Wheel) to maximize proc count.
• The spawned Egg Sacs are additional projectiles that themselves can deal damage, creating a chain of secondary hits. In packed enemy formations the output can multiply quickly.
• Spider Queen works best when the spawning chance is boosted. If passives exist in your run that increase on-hit proc rates, stack them with Spider Queen for explosive Egg Sac generation.

• Works well with Brood Mother: both are spawner-type balls that place more projectiles on the field; the two together create a dense web of secondary attacks.
• Works well with Egg Sac / Voluptuous Egg Sac: the Egg Sacs birthed by Spider Queen function like the Egg Sac ball, so any passives that boost Egg Sac damage amplify Spider Queen's spawned output.
• Works well with area-control passives: spawned Egg Sacs cover zone space — combine with wide-scatter or explosion passives to maximize their impact radius.
