Summarize the following:
This move is required to gain access to Regirock. Like the other Regis, Regirock is a level 40 Pokemon. Bring Water Pokémon to land effective hits. Bring along a Pokémon that can put Regirock to Sleep or Paralyze it, as well as a Pokémon that has False Swipes. Finally, make sure you're stocked up on Ultra Balls. You'll find the Desert Ruins on the east side of the Route. The Braille gives you instructions on waht you need to do to access Regirock.  Walk two steps to the right and then two steps down. Use Strength at this spot and the door will appear. You only get one shot at Regirock, so you'll definitely want to save before approaching it. This will allow you to quickly reload your game and try again if something goes wrong. Start the battle with Regirock. Use your Water-type Pokémon to take out big chunks of Regirock's health, and then use False Swipes to lower it as low as possible without knocking it out. Hit Regirock with Sleep or Paralyze, and then start throwing Ultra Balls at it.
Bring a Pokémon that knows Strength. Get ready to fight Regirock. Travel to Route 111. Read the inscription at the back of the cave. Save your game. Capture Regirock.
