Omniknight

Purist Thunderwrath the Omniknight is a versatile melee strength hero who can take on the role of a support or, occasionally, a semi-carry, depending on the player's play style. A holy and courageous Hero, Omniknight possesses abilities that excel at protecting and aiding friendly heroes. His heal doubles as a nuke and he can grant any friend Magic Immunity, as well as blessing allies with a physical invulnerability and regeneration. Few can escape the mighty and heavenly power of the Omniknight and he is a powerful ally in team fights. He is a mighty tank, and one of the most difficult heroes to kill.

Tips

 * Omniknight usually purchases a Mekansm and Arcane Boots to continually have heals during team fights and lane pushes.
 * Other slows are able to stack on top of your Degen Aura so it is fairly common to purchase a Shiva's Guard to be able to slow your opponents down even more than what you normally could.
 * If you are attempting to save an ally from death, use Purification before using Repel on them, because Repel will prevent you from using Purification on them.
 * You can use Purification to deal a lot of damage early on, or even causing first blood, especially at level 3 and 5.
 * Repel can be used on enemies, you could use this to great effect if you want to for example single out a priority target while your teams Naga Siren has used her Song of the Siren. (Keep in mind you must use repel before song, as all heroes are invulnerable to both buffs and debuffs while affected by the song.)
 * Repel can completely block the effects of some ultimates, an example being Tidehunter's Ravage.
 * Guardian Angel can turn the tide of many battles! Don't be too shy when deciding when to use it.
 * Attacking an enemy who is running from you can give them time to escape Degen Aura. To keep them slowed, run with them instead.  Try to get ahead of them if possible.  Then you can hit them or heal while blocking their path.
 * Omniknight's ultimate is very effective against any ability that deals physical damage; for example, it can be used to negate Juggernaut's Omnislash.
 * If you have to initiate, use Repel on the carry first, then activate your Guardian Angel. This will give your team the upper hand in a teamfight.

Trivia

 * Some parts of Omniknight's bio is a reference to the bible story of Daniel in the Lion's Pit. Daniel was thrown into the lion's den for praying to God and challenging Darius' command not to do so, but God prevented the lions from harming Daniel, saving his life. Similarly, Omniknight was to be thrown to the pit of sacrifice for challenging his priests but the Omniscience revealed itself, saving Purist.
 * His response I have gazed into the Omniscience, and it has gazed into me. is  a reference to German philosopher Nietzsche's quote “If you gaze long into an abyss, the abyss will gaze back into you”
 * His kill response You chose poorly. is a reference to the film Indiana Jones The Last Crusade.
