Omniknight is a hero in Dota 2, a popular multiplayer online battle arena (MOBA) game developed and published by Valve Corporation. Omniknight is a support hero that excels at healing and protecting his allies, as well as providing crowd control and damage mitigation.
Omniknight's first ability is Purification, which damages enemies in an area and heals allies, making it a versatile ability for both offense and defense. His second ability is Heavenly Grace, which provides a targeted ally with increased status resistance and movement speed, making them more difficult to kill and more mobile. Omniknight's third ability is Degen Aura, which reduces the movement and attack speed of enemies around him, making it easier for his allies to catch and kill them.
Omniknight's ultimate ability is Guardian Angel, which provides all allied heroes with a large amount of physical and magical damage resistance for a short duration. This ability can turn the tide of team fights and make it very difficult for the enemy team to kill Omniknight's allies.
Omniknight is typically played as a support hero, staying near his allies and using his abilities to keep them alive and protected. He is particularly strong when paired with melee carries who can benefit from his Degen Aura and Heavenly Grace abilities, and when facing teams with a lot of physical damage. However, he can struggle against heroes with long-range abilities and magic damage, which can bypass his damage mitigation abilities.
