Cloning

You can use one action to make an identical clone of yourself in any unoccupied space in 60 feet of you which you can see. It cannot be identified by nonmagical ways. The clone has everything you have, the same weapons, proficiencies, armor class... with one change, your clone has one hit point, which doesn't change. The minds of you and your clone are synchronized, so you think the same things. This means that you can communicate even when one of you can't talk and/or is deafened. You can use your clone's senses as well, as if they were yours. You can act with both characters as if they were different characters. At any given time, you can both use one action to swap places. 
When the clone dies, everything that was summoned with it, disappears together with it.
