Hax abilities in-lore

So what are the abilities in-lore of champions that could be called haxs? Some example I thought of would be telekinessis (many champs have this but the most common example is , wither which is basically an undodgable instakill unless you can't age (*laughs in , and *), Rune Prison and Teleport (Unless you know how to disspell it you can't get out and it can't be dodged, and even when you know how to it's very hard, as knew how to disspell 's wards and he couldn't get out of it), True Ice (can't be melted and you need huge amounts of power to crack it), Blood Magic (if you don't know how to defend against it and you have blood, you are basically drained of all your blood in a second, or your blood boils up inside you, or you get an internal hemoragy in your brain and other things like that). Which other champions would have abilities that would be considered haxs in your opinions?
