Having pet heal at 90% is dangerous in most bosses with potion cool down as because every hit will activate the potion cool down and you will find yourself dying because you can't heal when you need it. 50-60% is more reasonable when fighting with a potion cool down.
Although having auto potion in the higher difficulty of magnus is not optimal due to potion only healing 10% outside the blue barrier. (In easy mode, potion only heal 50% outside the blue barrier if you are not zombified).
Staying out of range of Magnus spin attack is your first priority.
Dodge any attack that take Magnus 4 seconds to charge up, they hurt alot (straight up kills you at normal/hard)
Dodge the meteor if it is humanly possible.
Magnus (and most bosses) is at their most dangerous when they are walking toward you because they can attack anytime and you can't dodge if you are in an attack animation. It is safest to attack the boss during their attack animation.
Standing in range of Magnus spin attack with a meteor behind you is suicide.
Pay attention to Magnus web debuff, it does no damage but it web debuff slow you and prevent you from using any mobility skill.
Anima Hero's Will will cure zombify and web, but knowing when to use is a difference of 1-2 life on average.
