sion is good early game and is even beter late game
so the way i start a game is get a vamp scepter and get enrage first and keep it up at all times so you get the max amount of health as Possible and once you and your teammate engage you can deal a lot of damage quick because the extra damage from enrage and the amour pen on your masteries and runes next get your cryptic gaze and stun when they push out a way and thats when you engage then you get your death cer*** then you try to max your enrage but when your level 6 get your ult and when you go to take down turents without minions use your ult to hit minions t heal and to hit faster sion is also very good for back dooring

when ever you get a chance to farm do it you will need it because it will give you extra health and the way i have him set up he is verry fast and has crit damage
