Can I skip "down" here? Does it still make a sense without "down"?
Good question! Yes, you can omit "down" here. "Down" in this context is a preposition and makes the term "descend down" become a phrasal verb. However, to "descend" already implies a downward movement, and so the preposition "down" is not necessary here but can just be used to add emphasis.
