Erg, The Earth Shaper

Passive - Living Wall: Erg has an extra-wide hit box and is treated as terrain

Q - Ravine: Erg channels for .5 sec before slamming the ground with his fists, creating two parallel walls that last for 4/4.5/5/5.5/6 secs

W- Raze: Erg charges in a target direction for 1/1.2/1.4/1.6/2 sec pushing minions,monsters, and champs along that he comes in contact with. If Erg hits terrain while charging he does a percent of his targets max health in magic damage. reactivate to stop where you are at and gain a shield

E - Monolith: After a short delay Erg creates a pillar at the target location that deals magic damage and knocks enemies aside that are caught under it. Monoliths last three hits and only only two Monoliths can exist at a time.

R- Masterpiece: Erg can instantly cast another ability for no mana cost and becomes 20/30/40% resistant to damage

Erg is a tank/support who peels for carries by changing the landscape around him. he is really tanky and and his abilities do average damage if they hit but all of his abilities telegraph his intentions very clearly, so he gets countered by high mobility champs. He could also be a malphite rework.
