All of you guys say you want to a champ that works with a pet or ally. My champion concept that I posted revolves completely around that concept. http://boards.na.leagueoflegends.com/en/c/skin-champion-concepts/eeTGjrhl-champion-concept-cervius-the-puppet-master
My champion concept is about a man named Cervius: The Puppet Master. He has a marionette named Sylvia that he fights with. He has two ability sets. One when Sylvia is active and a personal ability set if Sylvia were to get shut down. Cervius and Sylvia have separate health bars, so Sylvia's abilities will be active when she is along side Cervius. When she runs out of health, she will shut down and enter self repair mode, leaving Cervius to fend for himself, which he is fully capable of to an extent. If Cervius dies when Sylvia is active, she will make her way back to base but will be completely vulnerable since there is no one to control her. Once she is fully repaired, Cervius' passive, Vivace, will activate, teleporting Sylvia right to him, allowing you to make some dastardly plays since Sylvia is coming out of nowhere. With Cervius' abilities, he has more control over the field, but with Sylvia's abilities, you can make devastating combo attacks and really keep your enemy at bay while Cervius stays far out of harm's reach. If Sylvia is active and you choose a target to basic attack, Sylvia will attack it first, allowing Cervius to attack the same or separate targets.
That was only a brief description about the teamwork capabilities between the champion and his ally. Check out the page to read about everything there is to know about Cervius. The lore is long but really descriptive and is a very interesting story. His abilities are described in full detail, along with his fighting style, and game play, and even things you would hear him say in the game. If you skip the lore and go straight to everything else, some of it may not make sense at first. The lore literally explains EVERYTHING. If you like the concept, be sure to give the post an upvote and comment your thoughts.
