Pugna

Pugna the Oblivion is a ranged intelligence hero who uses his powerful abilities to destroy the enemy team. He has an enormous Intelligence growth of 4.0 per level, and an abysmal Strength growth of 1.2 per level - so make sure you build items accordingly. Pugna is one of the minority of Heroes that can use his spells to take down Buildings. Able to humiliate other magic users with his Nether Ward, Pugna can also siphon the life from creeps or Heroes to replenish himself. He is a unique Hero that is highly rewarding to master. All of his spells can be combined in several ways and often have multiple uses. If the proper items are chosen to fill the holes left by his unique stat growth, he can be strong early game all the way into the far late game.

Tips

 * Make sure Nether Blast is always maxed first.
 * Nether Blast has a cast delay of 0.5 seconds.
 * 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. However, it is easily destroyed, so cast the ward in hard-to-spot places to avoid an early detection from the enemy focus fire.
 * Pugna's HP and armor is among the lowest in dota, so it is wise to buff him up a bit by buying a Mekansm or 2 Bracers.
 * In a tight spot, Pugna can cast Decrepify on himself and teleport back to base with a scroll. This trick works best when being chased by heroes that can't nuke you and are trying to auto-attack.
 * Decrepify protects against the following physical-damage abilities (provided the enemy has no magical orb effect item like Desolator, Mjollnir, or Maelstrom ). You can bait out these ultimates & stuns if you're in a 1v1 situation:
 * Juggernaut's Omnislash (ultimate)
 * Slardar's Slithereen Crush (AoE stun)
 * Razor's Eye of the Storm (ultimate)
 * Hitting a Nether Blast together with only Level 1 Decrepify may seem hard, so utilizing the delay of Nether Blast by first casting it and then Decrepify during the 0.5 second delay is a good way to combo the skills.
 * Building Refresher Orb on Pugna will let you place 2 Nether Wards at once. While the mana regeneration doesn't stack, a spell cast by the enemy will cause 2 bursts of damage provided both enemies are in range.

Trivia

 * Pugna has the most intelligence gain of all heroes (+4 intelligence per level).
 * According to Alchemist's voice lines, Pugna is composed largely of phosphorus.
 * Pugna's name may have derived from "pugnacious", which is an adjective that defines somebody who likes to fight and is eager to resolve conflicts with violence.
