Rengar

Counter Tips
Avoid dueling a Rengar when his resource bar is near full, as his skills will become empowered.
Buying an Oracle's Elixir or planting a couple pink wards at key pathways will deny the Rengar from roaming and assassinating your allies.
It's generally not a good idea to fight a Rengar near brushes, as he is able to leap onto any targets inside a brush.
