A New Rengar Mechanic
If Rengar kills an enemy champion or assists in the death of one, the enemy champion will drop a Trophy, which Rengar can collect by approaching it. Once acquired, the* Trophy* will count towards Bonetooth Necklace's unique passive, Mementos of the Hunt. Uncollected Trophies will disappear if Rengar moves than 1000 units away for longer than 8 seconds.
"Don't let your pursuit of trinkets cloud your reality. Remember what I taught you, Hunter. If you are to succeed in combat against the best of the Valoran, you must have fear, surprise, and intimidation on your side. But if any one element is lacking, it would be best for you to retreat. You must break them before you engage them. Only then will you ensure victory and have your trophy."
