Pugna

Pugna is a ranged Intelligence Hero who specializes in tormenting enemies with his spells, constantly spamming it until his foe withers and ceases of life. Pugna is one of the minority of Intelligence Heroes that can use his spell to take down Buildings can take on and counter almost any hero who relies on physical attacks, powerful spells, and high-health heroes. However, he is fragile and difficult to use effectively.

Basic Strategy

 * Make sure Nether Blast is always maxed first.
 * Nether Blast has a cast delay of 0.5 seconds. Note that during this delay you can press 's' to stop the spell and re-target it if needed.
 * Last hit the tower with Nether Blast if it's at risk of being denied.
 * ALWAYS use Nether Ward during team clashes. It costs a mere 80 mana and can often deal more damage than a Zeus ultimate during fights.
 * Pugna's HP and armor is amongst the lowest in Dota 2, so it is very important to buff him up a bit by buying a Mekansm or 2 Bracers.

Trivia

 * Pugna has the most intelligence gain (+4 intelligence per level).
 * According to Alchemist's voice lines, Pugna is largely phosphorus.
