Omniknight

Purist Thunderwrath the Omniknight is a melee strength hero who is renowned for his ability to protect his allies, preventing the enemy from easily killing them. A holy and courageous hero, Omniknight is an adept support whose powerful spells give his team strong early-game survivability. He possesses a strong healing ability in Purification, which can instantly heal the targeted ally and, if there are nearby enemies, deal pure damage in the same amount, allowing it to be used as a nuke. He is also capable of providing spell immunity to allies in the form of Repel, a basic ability that prevents himself or allies from being affected by most enemy spells. His passive ability, Degen Aura, can greatly slow the movement and attack speed of enemies, preventing them from easily using their physical attacks to deal damage. And finally, his ultimate, Guardian Angel, can provide complete immunity against physical damage to all nearby allies, completely nullifying the damage output of most carries for a short time. 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.

Recommended items
Starting items:
 * and Tangoes are necessary for giving yourself flexibility when healing from enemy harass. Since Purification is so inefficient at low levels, you need a way to regenerate health without sacrificing your mana pool.
 * potions greatly help you to maintain lane presence due to Omniknight's small mana pool and costly, spammable spells.
 * es should be taken to fill out any remaining inventory slots. Purchasing two of them allows you to either build a Magic Wand, or complete the two Mekansm components more readily.
 * can be helpful in making Omniknight even more durable in-lane by giving him even more armor. It can also be used to complete a Ring of Basilius by purchasing a from the side shop.

Early game:
 * are important on Omniknight as he can use them to take advantage of to slow enemies down, whether while pursuing during a gank or body-blocking chasing enemies attempting to kill your carry. As all of Omniknight's spells are very position-dependent, increasing his movement speed should be a major priority.
 * is very useful on Omniknight due to his small mana pool. Having the ability to give yourself 150 mana can easily be the difference between being able to cast your spells or not.
 * provides mana regeneration and armor to the lane, making things safer for Omniknight and his carry. The mana regen is especially useful as Omniknight's mana pool is particularly small in the laning stage. It can also be disassembled later on and the Sage's Mask recycled to build a Soul Ring.
 * is a situationally useful laning item to purchase on Omniknight, as his mana pool is very limited before he can purchase items to allow him to cast his spells. The passive HP regen gives him a measure of health sustain, and consuming it can give him enough mana to cast any of his spells at least one more time in a fight or gank if he runs out of mana.
 * 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 powerful support item that enhances Omniknight's ability to heal teammates and inflict pure damage. The item grants more strength, increasing Omniknight's HP and base damage, and some mana regen to help him manage his mana pool more efficiently. The active allows Omniknight to utilize yet another heal, or deal more pure damage in fights on top of Purification.

Core items:
 * should be the first major item that Omniknight purchases, as its active ability is what allows him to cast more than once every few minutes. By alleviating his mana dependencies, Omniknight can become much more active in teamfights and ganks.
 * is necessary to increase size of Omniknight's small mana pool, allowing him more frequent use of his mana-costly abilities. As well, the active ability allows him to replenish his and his team's mana pools, an essential duty for a support hero.
 * gives Omniknight more stats for little gold, and allows him to replenish 255 health and mana instantly, enough to cast any his spells.
 * s are a general requirement on support heroes, as map vision is a basic key to victory.
 * s are necessary on Omniknight, as being able to teleport in to save a teammate from a gank with your spells is a major advantage that Omniknight can capitalize on greatly.

Situational items:
 * provides Omniknight with a second source of healing, one that affects allies around him, and through spell immunity as well. Its all-around stats and bonus armor also help to increase Omniknight's tankiness, but make sure that your mana pool is large enough to support the use of Mekansm, as it is extremely costly in mana to use.
 * gives Omniknight nearly infinite mana regeneration and a hard disable, greatly increasing his teamfight contribution and his ability to gank targets.
 * provides Omniknight with a great amount of armor for durability, and intelligence for increasing the size of his mana pool. Both the active and passive abilities stack with Degen Aura, allowing him to drastically impede enemies' attempts to attack and move around in teamfights.
 * is a useful all-around utility aura item to purchase. The armor, HP regen and mana regen aura benefit your team, and the lifesteal and attack damage bonus give them an extra edge.
 * , besides giving all-around stats, further speeds Omniknight and his allies' movement and attack speed. The active charges can be used in conjunction with Degen Aura to further create a disparity in movement and attack speed between the respective teams.
 * is not a typical item to pick up on Omniknight, however, it does provide some strong benefits. The bonus strength and agility give Omniknight more HP and armor, and the bonus movement speed gives him more mobility, which can allow him to get in position to cast spells or apply Degen Aura to enemies. As well, the Greater Maim, which has a greater proc chance due to the extra attack speed that the item gives to Omniknight, allows him to slow enemies down even further with his attacks.
 * is an expensive luxury item, but can allow Omniknight to wade into the center of battles and cast spells to great effect. As Omniknight is already one of the most durable heroes in the game, increasing the size of his HP pool can make killing him a tremendous chore by the enemy team.
 * is a strong pickup as it can allow Omniknight to cast twice, as well as use Purification and Repel in quick succession. However, refreshing your cooldowns is very costly in mana, so it is highly recommended to increase the size of your mana pool first if you intend on building this.
 * is very hard to build, but can allow Omniknight to greatly hinder the enemy for as long as he remains alive in teamfights. As he can slow enemies down greatly with Degen Aura and is already quite hard to kill in fights, adding burn damage and more damaging right-clicks can turn him into a damage threat and not simply an inconvenience that prevents his teammates from falling in battle. As well, the burn aura induces a miss chance on all nearby enemies, reducing their ability to inflict physical damage even more.
 * are a very strong item to purchase on Omniknight in the late game, as he often builds a Mekansm and Arcane Boots already. Combining the two items into one inventory slot frees up space for more items in the late game, eliminates Mekansm's mana cost and strengthens its aura even further. As well, the self-dispel can allow Omniknight to instantly remove debuffs from himself that may be preventing him from contributing effectively in teamfights.
 * is a useful item on any support hero, and is no exception on Omniknight. Being able to re-position 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. As well, it can be cast on fleeing allies to save them from chasing enemies, further augmenting Omniknight's ability to save teammates who are in trouble. The extra intelligence is also useful for increasing the size of your mana pool.
 * is a useful mid-game utility item that can give Omniknight more initiation, utility and protection capability, once he has mitigated his mana deficiency issues. Using the active on an ally can allow them to initiate or gank an enemy, as well as letting them get right next to an enemy to hit them with Purification. If a teammate is initiated on by the enemy, using the active on them can give them extra magic resistance and give them temporary invisibility. Finally, Repel can be used as a last-ditch measure to remove debuffs from an invisible ally, such as.
 * is a strong utility item that boosts Omniknight's casting capabilities, and can be assembled more quickly by using the Energy Booster from a disassembled Arcane Boots. It provides HP regen that aids in Omniknight's survivability, and the increased cast range allows him to use Purification and Repel on allies from farther away, greatly increasing the survivability of his teammates.
 * is a good cheap support item that provides many uses. The extra intelligence and mana regeneration ensure that Omniknight almost always has 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 hard-disable an enemy, something that Omniknight otherwise lacks, and then get within range to cast Purification to deal damage to them, or can be cast on yourself to dispel 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 health and mana, making him more resilient and able to cast his spells, while the active ability allows him to contribute more strongly in teamfights, or provide True Sight once it is fully upgraded.
 * is a situationally useful utility item on many support heroes, and synergizes with Omniknight's abilities as well. It gives scaling mana regen, more armor and evasion, greatly increasing Omniknight's survivability against physical damage. The active can transfer the armor and evasion bonuses to a teammate, protecting them even more on top of Purification and Repel, or used on an enemy to inflict them with reduced armor and a miss chance that stacks alongside Degen Aura to greatly reduce their ability to inflict physical damage.
 * is useful for protecting Omniknight and his team against magical damage 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 strong utility item that allows Omniknight to greatly hinder enemies' attempts to focus down him or a teammate. The item's bonuses give Omniknight more armor and mana regen, increasing his durability and letting him cast his spells more frequently. Using Echo Shell on himself or a teammate in a fight allows him to use his enemies' disables and magic nukes against themselves, slowing the pace of a battle down and giving him more time to use his defensive spells.
 * 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 while your ultimate is on cooldown or you want to save it for more important situations.
