Game Start:
When the game starts and you want to skill W. With this you have many options early you can try getting vision on the enemy buff and steal it. Or you try a blind steal it.
When the minions pass the Inner turret try getting vision of you enemy laner and hit him with your W. Here aswell you can predict where he would wait under his turret and get a blind W in.

Early Laning:
Try farming saftly and hit your opponent with your W when he walks out of the minions. You can clear the minions with your Q and follow up with W if he hides behind them.
When you need to back buy Ludens components or and Darkseal. Or after you collected 2500 Gold you should definitly back to buy LOST CHAPTER, BLASTING WAND, DARK SEAL this will put you at exactly 105 Bonus Ap including DORAN'S RING. With this you can evolve your W and you get you first Powerspike.
Asoon you can finish LUDEN'S ECHO you should back and get it. This is your second Powerspike and you should do alot of Damage now.

Mid Game:
With the first two Powerspikes you can roam Bot or Top and getting some kills. Use your R more for defensive playes or repositioning. With the shild of your R and Barrier you can get a very high shiled to survive alot of Burst damage, and kill your opponent.

Team Fight:
Try staying far behind your team you can spamm you W aslong you hit enemy champions. If somehow an enemy come onto you hit him with your w and use your R to reposition before he touches you. If possible go near your team so they can cc him and keep him from you. If you close to enemys eiter back off and make some distance or go in and help your damage with auto attacks to proc you passiv.
