Dota 2/Pugna the Oblivion

Pugna is a ranged intelligence hero who is usually played as a semi-carry and pusher. He is notable for having the highest intelligence growth in the game. He can spam his Nether Blast to rack up damage a lot of damage and even push down towers. He can use Decrepify to alter the state of an enemy, slowing them down and making them more vulnerable to magic. His Nether Ward will punish anyone who dares cast a spell by sending mana flares at them. If Pugna ever finds himself low on health, he can simply use Life Drain to sap an enemy's vitality for himself.
