Wild Pokémon Egg

A Wild Pokémon Egg is a type of Pokémon Egg that can be found in various locations in Altaris.

Mechanics

A Wild Pokémon Egg can be visibly seen in the overworld. If interacted with it when the player has room in their party, they can attempt to take it. If they do so, one of three things can happen:

The player is forced to have a battle with a wild Pokémon, presumably a parent Pokémon. The player must defeat the Pokémon they encounter in order to take the Egg. Attempts to capture the Pokémon will fail and use up the Poké Ball thrown. If the player chooses to run from the battle, the Pokémon will take the egg and run away. If the egg is taken by either the player or the Pokémon, it will respawn after a week. However, if the player blacks out as a result of the battle, they can go back to the egg for another attempt.

If the egg is taken by either the player or the Pokémon, it will respawn after a week. However, if the player blacks out as a result of the battle, they can go back to the egg for another attempt.
The player adds the egg to their party without incident. The egg will then respawn after a week.

The Pokémon Egg the player can get is determined randomly, with possible outcomes determined by the location the Egg is found in. The Egg determines the parent Pokémon that can attack player, if any at all. The Pokémon that attempts to steal the Egg is determined by the Egg's location.
