MATH FOR ABILITIES
Items: 
Runes: link
Masteries: link
Health: 4157 Armor: 365 -- 381 Magic Resist: 119 -- 137 Attack damage: 204 Movement speed: 400 Attack speed: 1,329 -- 1,877
I will do calculations on assumption that he have more armor than enemy.
Q damage: 373 physical damage. W damage: 272 (+50% of enemy's armor) physical damage. E bonus damage: from 76,7 to 79 bonus physical damage every second attack; on average about 39 bonus damage per attack. R passive damage: 219 -- 228,6 (+60% of enemy's armor) per basic attack.
Average estimated damage per 5v5 fight: 2294 physical damage + 340% of enemy's armor as physical damage + 160% of enemies armor as true damage; So, if enemy have around 140 armor: 2770 physical damage + 224 true damage. Maximum estimated damage per 5v5 fight: 3800 physical damage + 460% of enemy's armor as physical damage + 240% of enemies armor as true damage; So, if enemy have around 140 armor: 4444 physical damage + 336 true damage.
His damage is somewhere between AP+ARMOR 
and AD+HP 
His tankiness is somewhere between HP+ARMOR and HP+ARMOR 
LORE
There is a world of perfect harmony, where all are part of the whole. The Monolith is the essence of all creation, and its denizens are but singular pieces of it. It is beautiful in its symmetry, and in its almost complete lack of uncertainty. The rocky beings that live there know their place and work to fulfill their duties to the fullest extent, functioning almost as a superorganism or hive. Being part of this world Jeremnium also was mindless part of that world. However, something changed within him and he slowly become more and more violent, more and more chaotic. Bringing havoc and chaos through out the Monolith he become hated and despised, so he was retrained and banished into a dimensional rift between worlds. Flying aimlessly in the space between dimensions he had glimpses into many different world and finally ended up in the Void. There he had to fight to survive against countless number of voidborns. Battle after battle he felt more alive and filled with joy, and rage. Lust for fights materialize withing him causing his rocky core become hot and boiling. Once made out of rock, he become hulking juggernaut of hardest minerals and lava. But alas, no one managed to quench his thirst for battle, or his need for progressing world. He sometimes even let his enemies to strike a first blow or sometimes fight only using one hard so that fights would last longer, however it is all in vain, because as fight goes on Jeremnium becomes more and more enraged abandoning everything just to win a fight. However, besides his HOT temper, he have intelligence well beyond of normal person. When new dimensional rift opened he jumper into it in hopes of finding a world more suited for him and and ended up in Runeterra.
~~ ~~
He fell out of dimensional rift to a place nearby Bandle City and first living person he met was a little yordle. Yordle: Whoogh, are you alright? You just felt out of the sky. Jeremnium: ohhhh, my body... What is this world... You there, are you good fighter? Yordle: who, me? Nahh, i am just collecting flowers around here. Who are you, mister? Jeremnium: i am... (he looks around). This world is... What is that? (he shows at grass) Yordle: this? Chi chi, don't be silly. This is grass. Jeremnium: grass... It is so... I never seen this color. What is that color? Yordle: that is green. You never seen green color? Jeremnium: that's what i said. (he stands up and looks around). So colorful, so bright. Why? Yordle: why is what, silly? Jeremnium: why is this world so peaceful?
~~ ~~
Little yordle told him everything about Valoran and what people live there. About war between Demacia and Noxus, about humans, yordle and other races, all history little yordle knew. Learning it all, Jeremnium was intrigued. Number of opponents to fight, number of places to visit. Yordle: you really love fighting, don't you, mister lavaman? Jeremnium: well, fightin' keeps me alive, but it is not the fights i love. You see, in the world i come from there were only peace, stagnation and boredom. A little chaos what every world needs. Yordle: sooooo, you want to destroy stuff? Jeremnium: no, it's no the destruction. You see, every world need evolution. Nothin' happens in the world of peace or in the world of chaos. For world to evolve it needs those who brings chaos and those who brings balance. I want evolution, progression. Somethin' is created when there is problem to solve. Everythin' need changes, everythin' need a light and a dark side. It just happens to be that i am on the side of chaos. Yordle: do you any friends, mister? Jeremnium: who are those friends you speak about? Yordle: it's people who you pick flowers with, play games with, sings songs with. Jeremnium: no, i don't have any friends.
~~ ~~
On his way to Noxus Jeremnium was spotted nearby the Institute of War. Several warriors were send to stop him in his tracks and bring him in. After 6 hours of fighting he was finally suppressed and taken into Institute.
