I almost always win lane with her but I just can't seem to really impact teamfights later. I generally use the standard slightly tanky AP items and masteries, anything specifically core on her to have a meaningful late game?
Or is it possible that I am affecting things but it's hard to really notice just how much damage I'm doing when half of her abilities hit 3 different targets rather than stacking? --- If Pluto is not a planet Europe is just West Asia.
She's not a lategame powerhouse. You do have the ability to constantly be spreading Liandry's around onto most of the enemy team, so that can help you out a bit. --- http://gamercards.exophase.com/204819.png http://raptr.com/badge/Mistilteinn/fs_lastplayed.png
Other than being able to chase down low health enemies with her ult, she barely has any teamfight presence lategame. Her true damage is mostly a gimmick, it only constitutes a small part of her overall burst. It's nowhere near as scary as Darius, Irelia, or Olaf's true damage. She's kind of like Elise late game where she has to spend most of her time poking enemies with her skill shots, and once the enemies are low on health, finish them off with ult as they try to run away.
