Selt's Egg

It spawns an egg when the player enters an unexplored hostile room. After 3 seconds the egg hatches into a friendly Larva that has 5 HP. It shoots web balls that ensnare its target and inflict 10 points of damage. It immediately dies once the room is cleared of enemies. If the player is far enough from enemies they will target the Larva instead.

The Larva will not spawn if the egg is destroyed before it hatches. The player can destroy the egg themselves but is unable to hurt the Larva that spawns from it.

Its Blueprint are found after defeating Selt, Queen of Sand for the first time.
