A Champion Who Can Passively See The Invisible
"Shadow Isles Medium"
No but seriously, I think that would be a pretty unique champion, an oracle of some sort. You can definitely see where they would excel, and who against. But if your passive only allows you to see invisible units (for the time being let's exclude wards and focus on invisible champs), that has some drawbacks against people who clearly don't go clear (pun intended).
I'm too lazy to come up with an actual champion concept, the last one I put work into never got noticed. But do you think this would be a cool champion idea? At least the passive? Or do you think it would be too OP?
teacher perhaps.
They all offer stealth detecting fields and trap detection. Could easy be tuned for SR.
