I was in a barn when I fell off the 2nd to bottom step and broke my legs. I used "v" (the vault/overstep) to get up the stairs because I could not crawl up the stairs. I continued to vault to the top where I vaulted of the ledge at the top of the stairs, I took no damage. I vaulted up the stairs and over the ledge once more for no falling damage again. I was able to crawl of the same ledge to commit suicide.
