Dragon Knight

Davion the Dragon Knight is a very tough melee strength hero with a relatively versatile skill set. Dragon Knight has a nuke and a stun, giving him an advantage in ganks. Dragon Knight has no real escape ability, though his Dragon Blood ability and armor make him capable of withstanding strong hits and recovering quickly. He is still very vulnerable in the early game, however, and needs to farm and stay alive in order to be effective in later stages. If he has enough levels and farm, Dragon Knight is very formidable late game due to his strong ultimate, transforming into a legendary dragon, turning him into one of the most dangerous beasts in late game, capable of eliminating multiple enemies at once.

Tips

 * is one of the few heroes with no cast-time on his abilities, so spells can be cast in between attacks on the backswing animation.
 * is a powerful ability to have and should be taken before other abilities, but it levels poorly. Some players even choose to take Attribute Bonus over further levels in it.
 * Many guides recommend not leveling at level 11, but those guides are outdated. Prior to version 6.78, the Red Dragon did not carry over the corrosive effect from the Green Dragon, which made it inferior at pushing down towers. It is no longer necessary to skip leveling the ultimate at level 11. As of version 6.31, the corrosive effect also carry over to the Blue Dragon.
 * The splash attack from Red and Blue Dragon form is useful for clearing ancient creep stacks which can provide Dragon Knight a large gold boost. With a Dragon Knight can even stack the ancient creep camps with lane creeps by himself.
 * is a useful item on Dragon Knight, as it allows him to farm using Breathe Fire constantly, and the extra regeneration from Soul Ring and Dragon Blood offsets the health loss.
 * changes Dragon Knight attack from melee to ranged, keep this in mind when building items as it will also change the effect of items like damage block, bash chance or cleave.
 * Frost Breath and Corrosive Breath are not unique attack modifiers as such they will stack with items granting unique attack modifiers.
 * Lifesteal is a good UAM to have when using a, however does not benefit from Corrosive Breath because it is not physical damage.
 * is an interesting item to build on Dragon Knight as it provides another slow that stacks with Frost Breath and also pierces spell immunity. This will reduce an enemy's damage output significantly and make it hard for enemy heroes to disengage from a fight once they are attacked by Dragon Knight. It also provides a huge HP boost rivaling and can be considered a replacement.
 * improves Dragon Knight's tower pushing and increases his damage quite a bit.
 * A or a  will solve Dragon Knight's mobility problem and will allow him to initiate with Dragon Tail.
 * Dragon Knight has a high Effective HP against physical damage due to his armor even at the early stages of the match, however he is still vulnerable to nukes and disables as with most heroes. A will solve this problem and will grant a bit of damage and HP.

Trivia

 * In DotA, Dragon Knight's fun name was Trogdor, the playable character of a mini game from the Homestar Runner universe.
 * He also has an alternate name when he transforms with his ultimate in DotA, in which he is named "Arc Honist". This has been removed in Dota 2.
 * Dragon Tail is the longest (guaranteed) level 1 stun in the game. Mirana's  can stun up to 5 seconds at level 1, but must travel at least 1500 units and as such is difficult to hit with.
