What skills/items can you make OP?

Can you get to level 6 in time though? VS. all of these other skills >:)

The question's in the title, but let me explain the rules:

You cannot change the damage/range, but instead change a feature of the skill, say.. cm's ultimate changes from channeled to not channeled and follows her around like razor ult.

I don't mean simply buffing the damage or duration, but add in an additional effect, Laguna Blade now jumps to multiple targets etc.

Be as creative and crazy as you want, remember, the point of this is to change the skill/item to make it as OP as you can WITHOUT changing damage/duration/stats etc.

Have fun, and I will add an OP rating list and we'll see who wins >:) (no prize included, colours and contents may vary from illustrations)

<<<<WINNER

I really enjoyed making this little fun contest thread thing, and will do more when I have thought of different topics!

What, so banishing someone forever with Astral Imprisonment isn't OP?

It's annoying, but it doesn't result in them dying quickly (or at all for that matter) amirite?

It's basically disconnecting them.
