You definitely need drums. All that stats (more hellfire), and the speed. Fuck getting kited seriously. You need your male for damage, bm is cheap but not as good as mael so get it after. At that point of the game they can't focus you down anyway so bm is not very useful.
Blink is ok but they will just kite after, blink is for gank not teamfight. Plus it's VERY greedy spending 2k on an item only useful for ganking. I like to use the gold elsewhere.
