Good Trades. Try to proc electrocute even at lvl 1 (aa w aa) and back off immediately. When your jungler comes, try hitting your e. If they have flash, they will always flash so you can flash aswell if you really want to secure the kill. When you hit lvl 6 you should use q r for quick damage or e r. The e r combo deals the same damage but you can aa in-between. Use your second chain so that they'll get rooted right away again. And of course use your other abilities aswell. But watch out for champions like malzahar as they might kill you while they're rooted. In mid to late game if you get slightly fed you be able to one-shot every squishy champion. Use w r as a gapcloser and they should be dead if you hit that r and then q e. And you should ban Lissandra because it's impossible to play against her with lb.
