Instead of just making it so you have to beat something x times make it so you have to beat something without taking damage/ healing off all taken damage without potions (with badaid up) 3 times to auto battle, why 3? Cause for most people 1 or 2 coincidenses happen where you beat something without damage, but if you beat it 3 times then you probably have a consistent enough strategy that you can beat it without taking damage forever.
