[SOLVED][spell] Ritual of Doom

Hi guys, anyone know, what sacrifice when used http://dbwotlk.com/?spell=18540 ?
some video showed “kill” but other videos say that damage is only applied to 10% of max hp and guys can save mate.
Can’t understand what the dmg should be?

older wow versions killed one member, 3.3.5a damaged 90% of hp.
