Greater Spider Satchel

The Verduran Forest’s tiny tent-trap spider lays her eggs in a pyramidal web, and her young hatch only in response to intense vibration, such as the struggles of an ensnared insect or even songbird. Sadistic alchemists gather and augment these eggs, packing them in silken satchels that disgorge thousands of biting spider babies on impact. Many types of spider satchel grant a bonus to attack rolls.
