Puck

Puck the Faerie Dragon is a highly mobile ranged intelligence hero best known for being an extremely unpredictable and slippery target. Puck is commonly played as an initiator and ganker, with spells that are equally useful for super-aggressive maneuvers as well as daring escapes. Expert use of Puck's abilities will let you appear out of nowhere, suddenly leave your enemies crippled and disadvantaged, and get away in the blink of an eye - but mess up your timing or misjudge the situation, and there is little left to save this fragile Hero from death.

Tips

 * Puck needs a solo lane in order to capitalize on its powerful abilities, and can easily play alone even against a dual lane because of Ethereal Jaunt and Illusory Orb.
 * When escaping from danger, always Phase Shift after you use Illusory Orb. This way, you can sit invulnerable and wait for the orb to travel before you slip away.
 * The Blink Dagger is the perfect item to get on Puck, as it helps with initiating and escaping in addition to the many escape methods that Puck has.
 * Puck is probably the hero with most escape/survival methods. This makes for a good solo laner against a multi hero lane.
 * With a Level 4 Phase Shift and Blink Dagger, Puck can escape almost any dangerous situation with quick hands or queuing up spells. It is important to note, however, that Puck must still turn to cast abilities while phase shifted. Blinking out, for instance, can be very difficult if you wish to escape in the opposite direction, particularly if damage over time effects are active.
 * Phase Shift can even be used to avoid physical effects like Pudge's Hook.
 * Puck is great for playing mind games with your opponents. For example, instead of just using Illusory Orb to blink to safety, cast it and run in another direction! The opposing player will have to chase either you or the Orb, while you can choose whether to teleport... or not!
 * Mix Puck with a hero like Chen and you can use an Illusory Orb, then have Chen teleport you back to base to refill your bottle without leaving lane. Use Ethereal Jaunt to the orb before it disappears. (Showcased by Na'Vi in TI2)
 * Should you have a blink dagger, the ideal initiation combo is to blink in a group of enemies, Waning Rift, Dream Coil, shoot an Illusory Orb through as many enemies as possible but in a safe direction, Phase Shift, then use Ethereal Jaunt to teleport to the Orb. The silence from Waning Rift is more than long enough to execute this combination.

Trivia

 * Puck's alternate name was Kupu-Kupu, which means "butterfly" in the Indonesian language.
 * Puck was introduced in v6.48 as result of a hero creation contest for the Warcraft III: Frozen Throne fairy dragon model held by the dota-allstars.com forums.
 * Puck pays homage to a character of the same name from Shakespeare's A Midsummer Night's Dream; aside for Puck's playful attitude, its line "A midsummer nightmare" is also an allusion to the play.
