Effects[edit | edit source]

  • Adds a chance to fire an egg sack which spawns slowing creep. If an egg sack hits an enemy, a blue fly or blue spider is spawned.
  • Egg sack tears have considerably higher tear height and consequently, range.

Notes[edit | edit source]

  • Egg sacks will also spawn blue flies or spiders if they hit fireplaces or invincible enemies like Death's Head and Stoney.
  • The chance to fire an egg sack is affected by luck. It is 15% at base luck (0) but cannot reach 100% at high luck.
