Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Ok so this is my first time actually building this through non=game so if it doesn't work for you, sorry. Basically this is a complete attack speed/attack build with a bit of lifesteal for survival reasons. Personally, I like going middle lane in. Starting out with the poison really helps because the Damage over Time surprises alot of players. with the ignite, it almost guarantees the first blood. I do not have any runes because i am not level 30 yet but i would go for attack speed, attack and life or defense.
Beginning of game: Level(1-6)
If you are soloing mid buy: the Vampiric Scepter and just harass and if the enemy gets close and is beginning to wear down, use your ignite, it should be able to finish the player off.
If you are not soloing: Buy the Long Sword with one health potion. skills are the same order.
Mid Game: Level(7-13)
By now you should have malady and last whisper or boots by now. With these you can either keep laning and farm or you can lane and watch the minimap for small battles. If you see the enemy is turret hugging, check if they are low health. If the enemy is partially squishy then try to go through the jungle and finish them off with your ignite and poison. Try to not go against tank unless you are sure they will fall.
Late Game: Level (14-18)
Now is when you are having either the most fun killing off the team or having the least fun feeding. By now you should have either another last whisper or a blood thirster, depending on how you like to play, AS or AtD. You should try to keep you MQ on at all times and ghost at ready in case you are stunned or slowed.
I know this guide is not thorough but this build has been working for me. Hope you all like it
