Huskar is a ranged strength carry and ganker who is known for abilities which both cost his own health and which make him stronger as he loses health.
This makes him a very high risk, high reward hero, that can all-too often survive fierce engagements with just a slither of health remain, but on flip side can quickly be brought down and become food for the enemy team.
