New champ idea. Help me improve this.

Name: Clay

Race: Orc

Lore: Tunnels extend beneath Runeterra, a subterranean fortress lies at the heart of these tunnels called Underholme, a haven for a passive race know as orcs. Spiritual inclined beings, the orcs are drawn to the magics deep within the earth and rocks trace elemental powers left over from the rune wars. Some orcs harness these powers calling themselves Shaman. Though normally a peaceful race, the shaman were founded in case of dire times, to protect the orcs from the terrors that lie deep within the winding tunnels. The most prominent of these shaman is without little debate an orc known as Clay. Clay first rose to fame among his people when he defeated a cavern worm, a fearsome beast that slaughtered several of his orcish kin. This was no mere task as the worms were strong, with appetites larger than their length that usually stretched vast distances unknown even to those who wandered along their bodies, never to return. The battle between Clay and the great worm took 3 days and 2 nights, but eventually clay stood victorious. Many feats of strength followed this and clay became a great hero. Now an elderly shaman, his power and knowledge is vast, and he will do anything it takes to protect his beloved people, no matter the cost.

Appearance: Clay and his kin are greyish red in skin color, their mouths sport large tusks, and they have great physical strength from centuries of digging tunnels and building homes.

Clay's kit:

Passive: Totem Affinity-Clay gets 7% attack speed for each totem he has placed on the map. Additionally, Clay gains Elemental Power while moving or attacking, that is used to cast his ability's. Max 50 Elemental Power.

W:Totem of Rapid Water-Clay sets a totem down that heals him and his allies (Ap scaling here)+(base here) every 3.5 seconds. The heal proc rate is reduced to 1.7 seconds if Clay has 2 or more totems. 18 Elemental Power

E:Totem of Molten Flame- Clay sets down a totem that ignites enemies that are hit by Clay's basic attacks, causing (ap ratio here)+(Base ratio here) additional magic damage. 18 Elemental Power

R:Elemental Fury- For 8 seconds, Clay's auto attacks deal increased damage and double the effects of on-hit effects. 0 Elemental Power

Recommended items:

To Clarify a few things, The totems stay around until killed or Clay summons another of the same type, they provide vision, and their ability's only take effect if the target is within range of the totem(range to be determined). They can be placed anywhere and stay no matter where Clay is, unless killed or replaced. I intend Clay to be played Jungle or top Lane, as an auto attacking bully, using totems as supportive tools to secure the kill. The Elemental Power replaces the mana bar.
