This is what my endgame concept solves, it’s a great equalizer in term of damage type
Then once you kill baal, games you create have a new mechanic.
The more monsters you kill the harder the remaining ones get
+life, +damage ,+ resistance(including magic)
No more immunities, monsters are capped at 95. Resistances above 95 are added back as extra life
No more magic damage OPness since monsters gain resistance to it
