Dota 2 - Omniknight Build Guide

BIO
Purist Thunderwrath was a hard-fighting, road-worn, deeply committed knight, sworn to the order in which he had grown up as squire to elder knights of great reputation. He had spent his entire life in the service of the Omniscience, the All Seeing One. Theirs was a holy struggle, and so embedded was he in his duty that he never questioned it so long as he had the strength to fight and the impetuous valor that comes with youth. But over the long years of the crusade, as his elders passed away and were buried in sorry graves at the side of muddy tracks, as his bond-brothers fell in battle to uncouth creatures that refused to bow to the Omniscience, as his own squires were chewed away by ambush and plague and bad water, he began to question the meaning of his vows--the meaning of the whole crusade. After deep meditation, he parted ways with his army and commenced a long trek back to the cave-riddled cliffs of Emauracus, and there he set a challenge to the priests of the Omniscience. No knight had ever questioned them before, and they tried to throw him into the pit of sacrifice, but Purist would not be moved. For as he faced them down, he began to glow with a holy light, and they saw that the Omniscience had chosen to reveal Itself to him. The Elder Hierophant led him on a journey of weeks down into the deepest chamber, the holy of holies, where waited not some abstract concept of wisdom and insight, not some carved relic requiring an injection of imagination to believe in, but the old one itself. It had not merely dwelt in those rocks for billions of aeons; no, It had created them. The Omniscience had formed the immense mineral shell of the planet around itself, as a defense against the numerous terrors of space. Thus the All Seeing One claimed to have created the world, and given the other truths revealed to Purist on that day, the knight had no reason to refute the story. Perhaps the Omniscience is a liar, deep in its prison of stone, and not the world's creator at all, but Omniknight never again questioned his faith. His campaign had meaning at last. And there can be no question that the glorious powers that imbue him, and give his companions such strength in battle, are real beyond any doubt.

Why Purification first?
For survivability from firstblood attempt for you and allies in early game.

Degen Aura should be maxed in mid game because in this state of the game it will be lots of ganking. This skill is absolutely needed for chasing and escaping. And Repel: a 1 level of Repel is enough to survive the early-mid game.

STRATEGY

Early Game
You are a support type hero, your job here is to support your carry player to farm as much as he can, you must make your carry safe from death, guard him, use your Purification. Save him although with your own life :)

Mid Game
Mid game is the ganking time! Everybody will roam around the map and find somebody to kill. It's your time to roam too. Don't forget to buy the Smoke of Deceit to hid from enemy's Observer Ward.

You have some ganking skill here. So if you want to initiate in a gank, what you need to do is:
1. Comunicate with your teammates about who should be ganked, you should focus fire on 1 hero in a gank, because if you don't communicate well you may attack the A person and your teammates attack the B person, and that is a bad gank and can lead to failure on getting the kill.
2. Prepare the items needed in the gank:
a. Use Smoke of Deceit
b. Prepare Dust, Sentry Wards, or Gem if you will gank an invisible hero like Rikimaru, Clinkz, or Nyx Assassin

Here your part is to support your carry in ganking or protect your carry on farming. You may use the Repel before the ganking starts. And if important, you will need the Guardian Angel to guard your team. Also don't forget to cast the Purification on low health ally.

Late Game

Late game is usually the time for a decisive teamfight. Your part here is to make sure your team is protected from any threat during teamfights. Use your ultimate Guardian Angel in the beginning of every teamfight, and use Repel for allies who doesn't have Black King Bar, and use Purification for every one who needs it, if you see the low Hp ally, use it on him. If you do your job correctly, victory is likely in the hand.

After your team won the teamfight, you have two options:
1. You can get the Aegis for your team's main hero or
2. Your team can push enemy base and destrouy their buildings. Choose wisely!

Slower Oriented build
Here I will provide a build that is oriented in making your opponent moving slower, so slow that you can chase them so easily or escape from them easily.

note: upgrade Orb of Venom into Skadi cause Orb of Venom and Skadi do not stack
All of the items above makes the differenece between your movement speed and your foe's movement speed become so imbalanced. That makes you chase or escape so easily and kill your foe's easily. remember that you already have slower aura, that makes the thing so imbalanced in terms of differentiate of your movement speed and your opponent's movement speed.

Bad Enemies

1. Silencer

If you are silenced, you become weak, you can't support your friends.

2. Lion 

Have 2 disables, 1 mana burner, 1 high-damage nuke.

3. Zeus

Have many nukes that makes your ultimate seems useless.

Best Friends

All carry heroes like;

1. Magina

High damage, fast, very good escaper

 2. Faceless Void

Have chrono, makes enemies can't move under his chrono, try to use your ulty just after the chrono ends, makes your opponent in a very hard position because they can't attack.

3. Luna

Squishy carry, if you can make her live longer, she can wipe out all enemies because her high damage. The aura, bouncing attack, and her ultimate is so deathly

4. All carry from a to z

You can support all type of carry.

Weakness:

1. Diffusal Blade (and other purge: Satyr or Shadow Demon)

Diffusal blade makes it holder can use purge which will remove Repel and Guardian Angel. This item is a perfect counter for Omniknight.
