Obstacles:
* Blocked Paths: Rock Smash is essential for breaking rocks that block pathways in various areas, like the Ilex Forest, the entrance to the Radio Tower, and the route leading to the Ice Path. This would prevent you from reaching important locations and trainers.
* Hidden Items: Many valuable items, including TM's, Rare Candies, and evolution stones, are hidden behind rocks that can only be broken with Rock Smash. Missing these items would hinder your team's growth and progress.
* Evolution Requirements: Certain Pokémon, like Onix, require the use of Rock Smash to evolve. Losing the move would prevent you from utilizing these Pokémon to their full potential.
* Trainers: Some trainers, particularly in the Ilex Forest, have Pokémon that rely on Rock-type moves. Without Rock Smash, you'd be at a disadvantage against these trainers.
* Limited Access: The use of Rock Smash allows access to different areas, including caves and hidden routes. Losing this ability would limit your exploration and discovery of the world.
Potential Solutions:
* Trade: You could trade for a Pokémon that knows Rock Smash from another player.
* TM: If you find the Rock Smash TM, you can teach it to one of your Pokémon. However, these are rare items.
* Strength: You could utilize the move Strength to move boulders in certain areas. While not as versatile as Rock Smash, it can be helpful in some instances.
* Alternative Routes: If you are resourceful, you may find alternative paths or ways to navigate around areas requiring Rock Smash.
* Patience: You could level up your Pokémon and learn alternative moves to overcome the challenges presented by the lack of Rock Smash.
Overall: Losing Rock Smash in Pokémon Gold would be a significant inconvenience and a major challenge. It would require you to be more resourceful, utilize alternative strategies, and potentially rely on the kindness of other players to overcome the limitations it presents.
