He isn't usually a mid, but i was messing around and played him mid, and now he is one of my favorite mid champs because he doesn't need kills to snowball.

Pros - He does massive amounts of damage late game

Cons - Is killed easily, so you might need one health or armour item

His gap closer makes it easy to initiate then walk away while they are rooted. If you start off by Hooking them, then riptide, then Titan's wrath before you auto to stun (so combo is Q,E,W, then auto), then you can get in and do that combo and walk away while they are rooted.

His farming early is pretty straight forward just use passive to get last hits. Mid to Late game using E will kill caster minions in one hit and then make the melee minions one hits with your passive
