How to Super Leash Report

I call it a super leash, I don't know what other people call it. Most people don't know you can do this. It gives your jungler a huge advantage and you only miss 1 creep (you usually miss 1 when you leash anyway).

It's pretty situational, but really helps / shines when your jungler takes a different ability in order to invade with, and ends up being unable to kill blue after without help. You can super leash instead of having your team sit there helping with blue.
