eh u call the troll a overpowered absurdity? but that has nothing do to with spells
then u name a ghost which can go out of control so the ghost is absurd too?
spells make the game easier or at least doable in some cases
try using boss fights without spells or rage
gl with that
and as a side note of all this
you don't have to use those spells
or go for a no loss
