Morphling

Morphling is a ranged agility hero that has many flexible skills and item builds and is skilled as a very strong hard carry. He relies strongly on his attributes, and is an effective ganker. Unlike other agility carries who rely on physical attacks, he relies on his powerful abilities to initiate and shift into a state from which he can make a kill. Waveform lets him surge directly forward to a location, damaging enemies on his path, working both as a nuke or an escape. Adaptive Strike is an interesting scaling skill that blasts enemies with magical water while also stunning, knocking back, and dealing damage. Its power is based on either Agility or Strength. Morph allows him to edit his physical being, switching it from Agility or Strength, transforming him into a strong damage dealer or a tank. His ultimate, Replicate, creates a copy of either an ally or an enemy. At will, he can take on the place of that Replicate and instantly surprise enemies.

Tips

 * Boots of Travel is a commonly built item on Morphling. By using Replicate, then teleporting back to base, you can then instantly return to where you were with Morph Replicate. This strategy can also be used with Town Portal Scrolls.
 * Ethereal Blade is the most common and recommended item for burst damage on Morphling. By Morphing points into agility, he can cause massive damage with Ether Blast, and then use the amplified magic damage to finish an enemy off with Waveform and Adaptive Strike. This is sometimes referred to as the "Shotgun combo". However, do not build ethereal blade if Morphling lacks farm, as this item is most effective midgame, building it too late would not be useful.
 * Sometimes deciding which hero to choose for Replicate can be difficult, however potential candidates for this spell include: a hero with high DPS, those with favorable passives (such as Axe's Counter Helix) or even an enemy hero who has a Radiance or some other aura, which allows you to take advantage of receiving its effects for free.
 * It can be difficult to determine whether a Morphling illusion is real because it does not take any bonus damage unlike every other illusion in the game. You can use this to try and fool opponents into blowing long cooldowns.
 * A good Combo utilizing all skills would be Morph Agility Gain into Waveform into Adaptive Strike. Morph Strength Gain if things go badly. If the enemy retreats use Replicate then take the place of the replicate Or possibly waveform.
