Corynthus, the Magical Adapter is a custom champion designed for League of Legends.

Corynthus is a twenty-three year old Piltover citizen with a clean-shaven face. He wears simple clothing aside from a purple hooded cloak, to which he keeps the cloak up. His hair is rather lengthy, the brown strands flowing over his shoulders to continue down a short way. On his hip he carries his invention, the Hextech Magic Battery, a hextech device that slowly produces and stores magical power that can be harnessed by anyone who knows how.

The Hextech Magic Battery resembles a trio of boxes, lined up face to face and then turned away from eachother slightly, with pipes connecting the centers of the box faces. It converts and stores the latent magic in the air into a form usable by anyone, with each box containing a different step of the process. It was created after years of studying Ionian mages, and trial and error. The current Hextech Magic Battery is model 7, with the last six having all exploded upon attempted use.

Corynthus was born to a marginally more wealthy than average family in Piltover, so while he had a lot of what he could have wanted, he didn't have everything. From the moment he saw the abilities of hextech, he aspired to learn its wonders and make his own hextech devices. By the time he was moving on to higher education, he'd learned the basics, aspiring to major in Hextech Engineering and become an inventor.

After succeeding with his education, managing to place in the exact middle of the passing students, he moved into his own home and spent day and night researching and building experimental devices. Very few of them ever worked, and even then not for long. He eventually decided to set out on a journey around the world to observe different kinds of magic, hoping that it would help further his understanding of hextech, as part of it was magical, which he possessed no latent ability for.

Such a search led him to Ionia, where he discovered a pair of mages practicing day after day, to further their skills. Every day for the next three weeks, he'd hide and watch them, noting every little thing that they might have done. After those three weeks, he returned home and tried again, this time with a set goal: To create a way for anyone to use magic.

The Hextech Magic Battery was what he'd call it, as it would store magic that anyone could use, and in the end this is indeed what he managed to create. He moved from house to house often, as each time his next invention failed, it caused an explosion that ruined the building. Eventually he got it right, and has settled with the Hextech Magic Battery version 7, which he uses to this day as he wanders the world in search of ways to test out his newfound magic power, alongside his hextech engineering.

Hello again everyone, it's LancettaBreeze here. I got a really silly idea in my head and it slowly started to turn into its own champion design, so I decided to take it with open arms and turn it into a fully-fledged custom champion! His passive and each of his basic abilities have effects depending on the different roles of allied or enemy champions, meaning that he, the Magical Adapter, well - adapts to the situation!

I know, I know, that's a really basic concept, and that's really all I have to say after the fact, but I hope that this design came out balanced enough for all you custom champ critics. I'd love to see if I can't get this sort of thing noticed by Riot and maybe turned into a champion but I doubt that'd happen anyway, given where this is. Regardless of that though, I put quite a bit of time into this, so please give any sort of constructive criticism you may have!
