Bloodseeker is a mid ganking hero often outshined by some other heroes, but has a really fun aggressive playstyle that requires knowledge of enemy heroes to be effective! Ganking him on him is very common now due to the low cooldown of Rupture, and with a couple small damage items in his inventory, you can easily kill a support or two in teamfights, swinging them in your favor.

I recommend building utility items on Bloodseeker so that you can be a nuisance and useful all game, rather than carry items!
