Skeletron Prime
well, all bosses except twins have relatively stationary periods: destroyer's body can be continuously hit without taking much melee damage(though you might take projectile damage, which is minimalistic anyways), Skeletron prime's head is slow and easily targeted when spinning, golem is self-explanatory, duke is pretty stationary when changing phrases and the fetid is enough to skip its third phase if timed right, cultist doesn't move much at all despite being somewhat hard to hit, and moon lord deals no contact damage.you can't win a boss fight if you take too much damage and die
in fact, the fetid is one of the best weapons for melee moon lord.
also, with enough skill, it is possible to use this efficiently without taking crap tons of damage.
