Adds Egg Darts, currently only for Wyverns and Leedsichthys (No Untameables) but Rock Drakes, Magmasaurs, and Deinonychus are planned for the future.
Egg Darts cause a creature to lay a wild egg when close enough to a nesting location (they will NOT spawn eggs in random places, only the specified areas eg. wyvern trench egg spots). Egg darts may only be used once per creature.
Tip: Kite the creature around the trench/etc area to encourage egg laying, as they prioritize the closest nesting spot (which may not be empty).
Only works on child classes of the vanilla wyvern (some modded wyverns will not work)
