Dota 2/Lyralei the Windranger

Windrunner is a ranged intelligence hero who is usually played as a support or a semi-carry. Her namesake, Windrun, gives her incredible survivability. Her Powershot is strong and reliable, letting her do damage to enemies in a line and sometimes snipe heroes down. A well-positioned Shackleshot can be very powerful if she catches multiple heroes with it. With Focus Fire, she can overwhelm heroes and towers with a huge burst of attacks.

Shackleshot
Shackleshot sends out an arrow which will do a mere mini-stun and no damage to the target if there's nothing behind it. However, if the targeted unit has a tree or another hostile unit behind it, it will bound the two objects together, stunning any enemy unit including the target tied by it. It can be a bit difficult to land, but if you do land a full shackleshot, especially on 2 enemy heroes, then your team has an all but guaranteed kill.

Powershot
Powershot has a 1-second channeling time, after which you will launch a powerful arrow in the direction of the targeted area, hitting enemies in its path and destroying trees. Every time it passes through a target its damage will be reduced by 10%. The arrow is still released of manually canceled before it finishes channeling, though the damage is lesser. This spell is a very effective damaging skillshot, being able to wound mulitple heroes in one shot. It is also useful for scouting, since it grants vision around it. You can even use to snipe down enemies in the trees or in the fog-of-war.

Windrun
Windrun gives you increased move speed as well as 100% evasion against physical attacks while slowing the movement of nearby enemies. This is why Windrunner is considered one of the most-survivable intelligence heroes in the game. The speed boost and evasion can let her get away from a dangerous situation. the speed bonus is also useful for positioning yourself to land an effective Shackleshot or Powershot.

Focus Fire
Focus Fire gives you maximum attack speed on the targeted enemy unit or building for 20 seconds, though your damage will be reduced, including the effects from Unique Attack Modifiers and items. The speed will be lost when you switch targets. This ability isn't used very often, since Windrunner is more of a spellcaster than a dps dealer. It is a useful spell for pushing down towers, and is often used for that purpose.

 * Damage Reduction: 50% / 40% / 30%
 * Mana Cost: 200 / 300 / 400

Aghanim's Scepter can be bought by Windrunner and will decrease Focus Fire's cooldown and removes the damage reduction for unique attack modifiers and items.
