They could add usage or "Med kit" to revive as an option.
As well, allow to use items like food, draught or perfume category items, so you don't need to be forced to continue attempt buffless after dying and revival, or be forced to restart entire attempt just to buff up again.

You can choose more revive but it's useless because you can't use any elix or parfum so better restart everything if anyone die in the first phase
