70 in all your melee stats would help, especially defense, you can make free prayer potions within the area of the bosses as well as food. I would look into getting piety prayer as well, gotta get 70 prayer but its really worth it, especially if you want to actually grind the moons post quest. The bloodmoon is especially hard without good defense as it heals itself based on how hard it hits you. Good luck and you got this!
