Dota level 1 roshan kill

Here's a short video of my friend and I killing Roshan at level 1. We searched for guides everywhere and eventually had to just figure it out on our own, so I made this video for others. Basically you take Ursa Warrior's Fury Swipes passive ability at level 1, which causes him to gain +15 damage on each consecutive attack on a single target. Combine this with Lone Druid's Summon Spirit Bear to tank roshan, buy some defensive items + healing salves, practice a little micro, and roshan is dead before creeps even spawn. It's a huge advantage to start the game at level 4, and have an aegis, not to mention your allies each get +200 gold.

The trick is to never have more than 2 heroes/units attacking Rosh in melee range at a time, else he has a chance to slam the ground causing aoe damage to everyone around him.
