2 things,if its a heavy poke lane and you know you cant get it, go dorans shield. NEVER ever go dorans blade. its trash on talon. if you are against a squishy mage,go corrupting potion. you are gonna all in @ level 3, 2 points in your q and 1 in your w. pop corrupting before you all in him. use w to slow or you can flash w to cancel the cast animation to get him off guard. REMEMBER to pop corrupting,proc your passive and then ignite.

you can subsitute eletrocute for predator as well if you know you are gonna roam a lot to get a lead and snowball other lanes
