T5 revenant swapping?

[Flamez5304]

How do people do the thing where one person spawns t5 rev then they keep on swapping bosses and so on? I'm guessing its only during aatrox and with wolf pet maybe? Just wanted to know the official name because i didnt know what is was called and would be nice if someone told me how to do it too
