Thank you for the positive comments! I'd be happy to answer your questions:
 * 1) They have a shared duration, so if you apply a second or third egg, the duration for all egg stacks on your target refreshes to 10 seconds.
 * 2) The Spiderlings are designed to only be there for up-close damage, so no. If you move away, they will move around you so as to not block your movement (that's the idea anyway).
 * 3) I generally prefer to have cooldowns start the moment you activate an ability, so ideally the CD here should start immediately upon activation. The cooldown is high, but the effect is extremely powerful, and it's there alongside other hard CC abilities, so I want to make sure above all that you can't perma-CC your victim even with full cooldown reduction.

Thanks for the feedback so far! If there is anything I can clarify, explain or change, let me know.
