lvl 3 SOLO Roshan with Ursa - DotA2

I did not use cheats, I farmed the items in lane, went back to the fountain to buy, and then went to Roshan (So with a courier I could probably get to it sooner). It seems close, but it must have had bad luck when I recorded it, the prior 5 tries were never that close. I never died to him on lvl 3 with Morbid Mask Stout shield.
