Fenrir gains efficiency as he attacks. Every hit from a Basic Attack activates 1 Rune, up to a max. of 5. Each of Fenrir's abilities gain an additional benefit when used at maximum Runes and the Runes are consumed. Enemy gods that Fenrir kills will fully activate all of his Runes.
Fenrir leaps forward, dealing damage to all enemies when he lands. At full Runes, the leap Stuns the enemies hit. If the leap hits a god, the Cooldown is halved.
Fenrir rears back and howls, inspiring himself with a Physical Power and Lifesteal Buff. At full Runes, the Buff is increased by 50%.
Fenrir pounces to his ground target location. If there was an enemy in the radius, he strikes them 4 times, dealing damage with each strike while being immune to knockups. At full Runes, each strike deals 75% damage to nearby enemies.
Upon Ragnarok, Fenrir grows massive in size, becoming immune to CC while moving faster. Fenrir bites enemy gods, dealing Physical damage and carrying them away. Biting a CC immune target deals the damage but ends his Ultimate. At full Runes, his Protections double.
