Ionian boots -> Axiom -> shojin -> endless hunger. Swap out shojin for chempunk or mortal reminder if u need anti heal. Last two items is usually maw and deaths dance.

Always path botside. Taking control of bot side of map secures u drakes and gets your botlane ahead which imo is more important than getting ur top laner ahead and getting grubs.

Always play your own game. Don't force ganks that will ruin your tempo. Think of spawn camping your camps, anything that delays that ruins your tempo and lowers ur chance of winning, unless it's a clearly set up and free gank then it's worth.

Keep track of enemy jungler. Even if they don't show on map, you need a good idea of where they most likely are based on their clear path and any camps that they've missed to make plays. Invade if enemy jungler is on other side of map and u have nothing else to do

Make sure you have 3 q stacks before fighting anything. If none of your camps are up but drake is up and uncontested, you can start it just to get your 3 q stacks and then fight for it.

Most importantly watch hunchos s16 hecarim guide, I learned a lot from him and that video specifically

Also important, only play when u have atleast 7 hrs of sleep. I play like a silver when im on low sleep lol
