Lore: Hammer securities' ace pilot, Cain survives a life of military accomplishment and casual fame. But such trivial hallmarks to fortune are but a small drop in his delusions of grandeur. He wants more than this.

Cain is a semi-carry lane bully who does best solo mid, or with someone who can help him get more consecutive attacks off on the same target. He has trouble actually carrying due to how slow he is, but does serve as a tanky secondary dps. Max E first - note that the max attack speed stays for up to 15 seconds, which is more then the cooldown of the skill, allowing back-to-back E if you wait a bit. Run 1/2/3 talents, taking weapon damage, health, armor, cooldown reduction, energy regen, and movement speed.
