Please bear in mind this only applies if you aren't being heavily pressured in lane, and your team is not super far behind. I will explain to you item builds and why you get them. In this video I got Treads at 6 minutes, BF at 12, Vanguard at 15 and Manta at 21. These timings could have been much faster which I explain later. In this video I got 0 kills but also 0 deaths. There were some times where I could have increased my efficiency (such as farming mid lane w/BF) however for the sake of science I did not do so. I tried to emulate an even game where neither side is very far behind, but also made several assumptions. My supports/mid need to farm the mid lane in order to catchup, therefore I end up jungling as it increases the farm the entire team gets. If I farmed the lane I would get a faster item timing, however it would leave my supports/mid super far behind (as supports are usually unable to jungle very fast) and result in me being the only farmed hero on the team. Looking back it is probably better to buy Yasha, then Vanguard before completing the Manta as Yasha greatly increases your farm rate. However Vanguard makes you close to impossible to kill and also gives you +12 hp/second w/BF which is amazing sustain. If you can get away with it, buy the Yasha however usually Vanguard will come first. The most important part of the video is the first 12 minutes up until I get BF. The rest is just to show you how fast you can get your Manta. PS This works on both Radiant and Dire, however is arguably slightly better on Radiant due to the ability to pull through the Medium Camp, whereas on Dire you must stack the small camp and then pull as you will want to be farming the large camp. This means on Radiant you can pull the wave back ~30 seconds earlier while maintaining the same farm speed..
