Tanky and do a lot of dmg with flinged, People u need to learn to use flinged and w not just running, You do the most dmg with flinged against squishy. As singed you need to out lvl other people, teleport to where minion is and push, let your team come to you. you can get away easy with ghost and R and W.

PRO: A lot of ap dmg to squishy with no Magic Resist half health gone with one flinged.
Good against AP users, if they got a lot of ad change force of nature to angel or frozen heart.
3k hp at late game with no health item. Great dmg.
Help ur team escape with posion q and slow w
must solo top.
Cons: Not as fast, not good against people who has lots of magic resist.

Go in with R and ghost and flinged. Just use finged and run ahead of your enemy or squishy, and flinged again and he is dead. Reason why i think boot of swift sucks is because you do a lot less dmg and you run so fast that your team can't catch up which is bad. And sometimes u want them to think u are slow so they will chase u. if they caught up just throw a w and u can still get away or just keep running. With this build I win 90% of the times no joke.
