(Rework Concept) Malphite, The living mountain

The land around Runeterra holds many mysteries, but none so as the tale of the living earth. Some say that its hard to make maps of a certain area outside the reaches of Damacia, as the mountains are never in the same place as they have been seen last. Whatever causes this abnormality, its a wonder how it came to exist, and if there are other like it.

Passive: The Mountain Man Malphites body interrupts all Projectiles. (think of this like a Braum shield), his body of which grows in size scaling with his armor.

Q: Seismic Shock Malphite slams his arm on the ground, doing aoe damage

W: Magnitude 10 Malphite stomps on the ground, disorienting any enemies standing in the radius. They lose 50% attack speed and are slowed by 70% percent

E: Deadly force Passive: Malphites punches use the force of a whole mountain, doing aoe physical damage Active: Malphites next auto attack is empowered, dealing additional magic damage scaling off his armor)

R: unstoppable force Malphite charges in a direction, knocking up any enemies in a radius where his ult ends. Additionally, he destroys any terrain along the way for 10 seconds. Allies and enemies alike can travel through destroyed terrain.

This is kind of a quick concept i thought of, and i wanted to put it out before i forgot it. I would love to hear suggestions and feedback, as im not very good at balancing.
