If you’re neither a mountain/ rock climber but still know the answer, please help by answering this question!

What essentials would one need on an inclined (sloping) surface (ex. Mountain) that is not really required on a leveled surface (ex. Floor)? Please explain your answers!

This is a question the Holy Spirit deposited in my spirit during my personal morning prayer.Your answer will be an attempt to help yourself and others as you keep the essentials in mind and ponder over them, considering that your answer is correct. These essentials termed in biblical terminology and looking up scriptures on the subject will be of help to you and others in times of complexity if you allow it.
