Idea for new champion

New champion idea! Meet Amodaan. A black panther kinda shaped like Nasus but bulkier. He would have big rought stoney dark like armor. He would be half shadow, kinda like Nocturne, half animal. He would have a large rough stoney dark mallet. Face would be half/half shadow animal, and have glowing eyes.

Shadow Shield (Passive): Amodaan has a small shield that will slowly regenerate after being struck by damage og spells. Mallet Quake (Q): Amodaan smashes his hammer into the ground he knocks up enemies in front of him. (Like Aatrox's but shorter range) Dark Energy (W): Amodaan puts dark energy into his mallet increasing the next three basic attacks damage. Primal Leap (E): Amodaan leaps to the targeted enemy and slows them. Dark Rampage (R): Amodaan goes on a rampage increasing his attack damage, attack speed, and goes on all four increasing his movement speed.
