You will have to clik while spamming the macro the divine interventions once to keep it active durring the whole curse of the battle.
I haven't included the Sacred shield for 2 reasons, first cause you might have a paladin in your group healling and you dont wanna mess up macros before each boss fight, second cause i like to clik sacred myself when the time requires it.
I will include one macro with divine and sacred but later

"I don't want to kill you, but if you advance, I will have no choice. Then I will kill the kindness in my own heart, and fully embrace death. Then there will be no mercy, no turning back. This bridge will be the battle field where our dreams collide, now I must fight for my dream, just as you fight for yours. Please do not blame me. I fight for someone who is precious to me. I live for him, and I'd face death for him, so that his dream will become reality. That is my dream, and for the sack of that dream, if I must, I will act a beast, and take your lives"
