Try and invade if you can if not take your red side then your blue side then try and gank cause u have lvl 3 and your ganks are now pretty safe and then just rinse and repeat until you have your first 2 items

Just be roaming around and try and make a lot of jungle pressure by pushing up bot or top with your laners and hopefully get the turrets

That’s it your fed you have most of your items and you win no one can stop you at this point
