Dota 2/Traxex the Drow Ranger

Drow Ranger is a ranged agility hero that is played as a hard carry. Her skill with the bow is quite amazing, giving her a great attack range. She can slow enemies down with her deadly Frost Arrows and buff her teammates with her Precision Aura. If she's up against any spellcasters, her Silence will render them helpless. Her great Marksmanship lets her achieve the high damage output of other hard carries earlier. While unremarkable at the start of the game, she can become an absolute terror once she's farmed up.

Frost Arrows
Frost Arrows is a toggled ability that makes you attacks slow enemy hero for 1.5 seconds and slow enemy creeps by 7seconds. Using Frost Arrows on a single enemy will not cause the slow to stack, but merely resets it, It is a Unique Attack Modifier, and thus cannot stack with other Unique Attack Modifiers. While you can auto-cast it to apply the effects to every attack as long as you have the mana, it is not recommended since you can manage your mana more effectively and won't draw enemy creeps to attack you. An 11% slow at level 1 is already much higher that what the Orb of Venom grants, and at level 4 it becomes a ridiculous 50% slow. A great harassment tool to scare your enemies off as well as a deadly slow that can prevent wounded enemies from escaping.
 * Ability: Auto-Cast, Target Unit
 * Affects: Enemy Heroes
 * Move Slow: 11% / 24% / 37% / 50%
 * Mana Cost: 12

Silence
Silence simply renders any enemy in the targeted area to lose the ability to cast spells for a certain period. While an ability like this might seem odd for a hard carry, it helps you deal with pesky disablers who loves to stun you as well as any powerful nukers trying to burst you down. The duration is actually longer than most other silences, letting you annoy enemy spellcasters to no end.
 * Ability: Target Point
 * Radius: 300
 * Duration: 3 / 4 / 5 / 6
 * Mana Cost: 90
 * Cooldown: 15

Precision Aura
Precision Aura increases the physical damage of you and all ranged allies nearby. A damage boost is always welcome, especially since ranged heroes will usually have less base damage than melee heroes.
 * Ability: Passive, Aura
 * Affects: Allies
 * Radius: 900
 * Ranged Damage Bonus: 7% / 14% / 21% / 28%

Marksmanship
Marksmanship gives you more agility. While it doesn't sound very remarkable, when you do the math you will gain about 6.3 armor, 45 IAS and 45 damage by level 3. With this ability, you can match the dps of other hard carries without needing to buy all the usual hard carry items.
 * Ability: Passive
 * Bonus Agility: 15 / 30 / 45
