Omniknight

Purist Thunderwrath the Omniknight is a versatile melee strength hero who can take on the role of a support. 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 Spell Immunity, as well as blessing allies with physical invulnerability. 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's greatest strength is in protecting teammates from harm and preventing their deaths in dire situations. As such, he should be built for mobility and casting, as he requires good positioning and a sustainable mana supply in order to perform at his best.
 * Due to his tanky nature, Omniknight is a good hero to build aura and teamfight items on, as he is less likely to die before casting his spells and is his team is more likely to benefit from the auras for an extended duration. Aura items such as Drum of Endurance and Vladmir's Offering can benefit the team for longer, and active items such as Mekansm, Pipe of Insight and Crimson Guard are more likely to have their abilities used before Omniknight dies.
 * Silences are one of Omniknight's greatest weaknesses, as most of his spells are active abilities that must be cast. It is recommended to either pre-emptively cast Repel on yourself to prevent yourself from being disabled at the start of a teamfight, remain behind teammates so that you do not get initiated on, or build an item that allows you to remove silences from yourself.
 * is a very strong damage nuke and heal, capable of healing an ally for 360 HP and dealing the same amount in Pure damage to all nearby enemies. Casting the spell on an ally who is engaging an enemy at melee range will cause a 720 HP difference shift between the two, often enough to completely change the situation in favor of your team.
 * Keep in mind, at low levels Purification will not heal very much and costs a moderate amount of mana. Therefore it is not recommended to use it solely for topping up a teammate during the laning phase after taking damage from enemy harass, but rather when you are aiming to use it both as a damage nuke and heal at the same time.
 * If you are attempting to save an ally from death, use Purification before using Repel on them, as Purification cannot be cast through spell immunity.
 * is a very powerful spell in that it can be cast on allies in the early game, when nobody on either team has enough gold to purchase a . Use this to your advantage to get off early ganks and win early teamfights by giving your teammates an advantage that they normally would not have.
 * At maximum level, Repel lasts for 12 seconds and has a 14 second cooldown, meaning that you can give a teammate spell immunity more than 85% of the time. This can be useful in the late game when a Black King Bar will most likely only last for 5 seconds, and any s that the enemy has purchased to counter you are out of charges.
 * Keep in mind that unlike other types of spell immunity, Repel will not remove buffs placed by allies (runes will still be dispelled). Therefore, if a teammate has a castable buff that can be removed by spell immunity, it is possible to cast Repel on them so that they have spell immunity and retain their buff.
 * Remember that Repel can be cast on enemies, and will remove purgable buffs from them, so you can use it creatively. For example, it can be cast to remove a buff placed by an enemy Dark Seer, or to prevent an enemy from being affected by an ally's Naga Siren's  so that you can focus them down while the rest of their team is disabled.
 * retains its debuff on enemies up to 2 seconds after they leave its aura radius. Therefore, it is possible to spread the debuff to multiple enemies in a teamfight at the same time by walking near them.
 * Other slows are able to stack on top of your Degen Aura, so it is fairly common to purchase a Shiva's Guard or Orb of Venom to be able to slow your opponents down even more than what you normally could.
 * When chasing an enemy with Degen Aura, the most efficient way to slow them down is to get close enough to apply the debuff to them, and then walk ahead of them to body-block their path and apply any attack modifiers that may slow them further.
 * can turn the tide of many battles. However, it also has a very long cooldown, so be sure to reserve it for the right occasion.
 * Omniknight's ultimate is very effective against any ability that deals physical damage; for example, it can be used to negate Juggernaut's or Death Prophet's.
 * Remember that even though Repel does not remove ally-placed buffs, other sources of spell immunity will. However, the buff can be applied through spell immunity, so if your team's carry has a Black King Bar, be sure to cast Guardian Angel after they activate it.
 * Omniknight has many good items he can build besides those recommended by Valve.
 * is a useful early-game item to buy, as its slow stacks with that of Degen Aura, slowing a single target's movement speed by up to 46%.
 * is a useful item on any support hero, and is no exception in Omniknight's case. Being able to reposition quickly can allow you to use your spells to greater effect, as you can get within range for casting Purification to deal 360 Pure damage to enemies, or instantly apply Degen Aura to a fleeing enemy. The extra Intelligence is also useful for increasing the size of your mana pool.
 * provides many of the same positioning benefits as Force Staff, but has a greater range that allows for far easier initiations and escapes.
 * is a good cheap support item that provides many uses. The extra Intelligence and mana regen ensure that Omniknight will almost always have the mana he needs to cast his spells, while the extra movement speed allows him to capitalize on Degen Aura more easily. The active ability can be used to disable an enemy and then get within range to cast Purification to deal damage to them, or can be cast on yourself to purge debuffs from yourself (such as silences which may be preventing you from casting your spells).
 * provides Omniknight with many benefits and adds to his pushing and teamfight contribution. The bonus Strength and Intelligence increase his HP and mana, making him more resilient and able to cast his spells, while the active ability can summon Necronomicon Warriors to further debilitate the enemy.
 * is useful for increasing Omniknight's survivability against spells in a teamfight, thus ensuring that he can cast his spells to their utmost and apply Degen Aura to the enemy for longer. The active ability also synergizes with his ability to protect his teammates from harm.
 * is a good pickup for giving Omniknight more resistance against physical damage, as he is a melee hero who must get close to the enemy to apply Degen Aura's debuff to them. However, its main use is in the active, Guard, which gives damage block and armor to all nearby teammates, very useful if you need to give them survivability against physical damage but your ultimate is either on cooldown or is being saved for later.
 * can be useful to build once you have all of your core items, as it can be completed for 3100 gold (1100 for the Vitality Booster, 1200 for the Point Booster, and 800 for the recipe) from your already-purchased Soul Ring and disassembling your Arcane Boots for the Energy Booster. It drastically increases Omniknight's HP and mana pool, while giving him almost everlasting mana regeneration. This allows players to place themselves in the center of teamfights and use their spells and item abilities to their utmost. As a last resort, the item's active ability Pocket Suicide can be used both to deny a kill to the enemy and to heal all nearby teammates one last time.
