[Champion Concept] Kor'Viak, The Ravenous Hunter
Champion Concept: Kor'Viak is a melee champion meant to either play the role of fighter or assassin ideally in top lane or jungle. It relys heavily on its ability to kill enemys within one burst as using its skills leaves it open for a length of time. It can be built with either straight ad with crit or attack speed or be built tankier to allow it a longer lifespan in teamfights. It's abilities, while useful, have longer than average cooldowns making kills more meaningful and focusing on killing a single target i.e. Main enemy threat or stragglers much more rewarding.
Appearance: Kor'Viak is a symbiotic moss-like organism that lives on the back of a creature from the Kumungu Jungle, normally taking the form of a fur-like substance but spiking or raising on ends when the creature it's attached to is enraged or on the defense.The creature it's attached to is a quadrapedal beast with dark brown fur and black smear patterns along his side. The beast's maw is somewhat canine in nature with a large lower jaw. It's claws are slightly retracted normally, pointing out at the tips but can be released to show sharp black claws. It's underbelly is a lighter shade of brown with a single black smear across it.
Lore: Within the Kumungu Jungle lives a myriad of dangerous and deadly creatures, from carniverous plants to vicious beasts. Among these beasts is a creature thatt some who have scouted the jungle from the Institute of War say dates back to times before the Rune Wars. Others say it was a beast born from the magic scattered across the land after said wars. The truth of it's origin is a mystery, but all the reports repeat the same. A large and brutal creature that attacked from great lengths and quickly disfigured and devoured several on site scouts, the remaining being heavily injured or mortally wounded. After much time, the Institute, unable to identify the creature, had Champions escort a group of scouts into the jungle to atleast gain an idea of what this creature could be. It did not take long to find it. After finding and sedating the creature with as much magic as they could, losing nearly half the crew, they were able to bring the creature to the Institute of War. Upon closer inspection, the creature seemed to be a normal beast found in the jungle, but the moss-like substance on it's back was not normal. After much experimentation and many lost scholars, the moss was identified to have properties similar to the creatures that had left the Void. After the final tests, the Institute named the moss-like substance and the creature it was attached to Kor'Viak, and with no other use for it, sent it to the League of Legends as both an executioner and an experiment to see what further information it could offer.
