Passive: Bounty: Cara receives an additional 1 gold whenever she kills a minion.  Additionally, whenever Cara kills an enemy champion, she'll receive a bonus 20 gold (half if she gets an assist).

Recommended Summoner Spells:
-Clarivoyence: So that Locust Beam will never miss!
-Ignite: The extra damage will help her kill enemies.
-Exhaust: An obvious choice.
-Cleanse: Cara is an AD carry, so Cleanse might be needed if she gets stunned, blinded, etc.
-Ghost: Not only for escaping & ganking, Cara can use this ability to position herself for her ultimate.

Tips:
For using Cara:
-Use Hextech Blossom to snare enemies so that your Hextech Grenade won't miss.
-Remember to position yourself so that your Locust Beam will hit the target!  i.e., don't use it if an enemy tank is in front of the target.
-Use Adrenaline Rush to help position yourself for Locust Beam.
-Use Clarivoyence when the enemy is right about to enter the fog of war!  Once the enemy enters it, Cara will just shoot in a straight line.  Using Clarivoyence AFTER the enemy enters the fog of war won't cause Cara is re-target the enemy.

When playing against Cara:
-When you see a green light pointing at an ally, try to get in front of it so that Cara's Locust Beam will hit you instead.
-When Cara uses Adrenaline Rush, wait to use your CCs after it is finished.
