lvl 1 even if the champions has a stronger level 1 like darius but make sure to always keep your distance. You can play aggressive against champs like renekton, darius if he goes q or w first, illaoi and fiora but always look out for her vitals. Your level 2 is quite strong but only if you take ignite many people underestimate flash [q auto ignite combo] and can be caught out for first blood. You can put points in w second if you know there are not many abilities that you can blind and you know you will need to kite. Harass your laner as much as you can but be careful for ganks as you most likely to be shoved in under their tower.

After 6 you want to be putting mushrooms down nearly every time you have it on the entrance to lane so junglers can't gank you and you need to escape from your top laner you can run through river. Also place them on the corners of the wall and make sure to sit near them when harrasin so champions like sylas, shen, trynd who have a gap closer get hit by it and slowed and you can w away. Make sure to always poke the laner if they are just walking away from a failed engage.

This is mostly all about shroom placement. Always have shrooms placed around an objective and keep putting them down because their cooldown is really short. Also try get your hands on a blue buff so you can just have a plantation of shrooms. In team fights make sure to blind the most fed person so they become useless especially if its and adc

If you do all this you will become the little devil of summoners rift. You may be arrested for psychological warfare and mental torture tactics. Your prison sentence will double if you duo q with a little devil fizz and you become the little devil duo.
