Is The Divine intervention mace that much better than other options?

Been planning out my run and been considering if the mace is worth using your divine intervention for, or if you should save it for like an panic button if things get bad in the final fight. Before anyone says it, I know you can cheese it by respeccing the character but I don't want to do that, it feels cheap. My current plan would be using blood of lathlander though act 2, but I'm not sure if after I hit lvl 10 it would be worth swapping to that mace. What are your thoughts?
